Duet2wifi RepRap CNC (7 replies)

MARCENEIRO JOVEM — Fri, 28 Nov 2025 09:02:00 -0500

Hello everyone.
I’m asking for help because I have already exhausted research and assistance from Artificial Intelligence Gemini and CoPilot. The problem: I have an operational CNC machine and decided to upgrade to a Duet2 Wifi controller. Everything worked except the Z-axis movement. It always moves 1/5 of the requested distance. For example, if I request a movement (positive or negative) via Web Control of 25 mm, it only moves 5 mm. If I change steps per mm M92, it produces almost no change. I have checked the Z-axis hardware and everything seems ok. Homing is OK. I have no idea what to do.
My setup: Duet2 Wifi controller, RepRapFirmware for Duet 2 WiFi/Ethernet version 3.6.1., Z axis Threaded Rod Stainless Steel M8x2mm Nema 23 motors (AK23/15F6FN1.8 model). Power supply 12v/ 30A), mechanical endstop switch.

Attached Config.g e Diagnostics.

I appreciate any help because I really don't know what to do.

CNC SCYLLA REVAMP (no replies)

Scylla CNC Build — Wed, 26 Feb 2025 08:08:33 -0500

So a few teething issues as follows any help would be much appreciated please.

I apologise if my terminology is poor this side of machine building is definately not my forte but willing to learn !

Im wanting to home both X and Y axis at MINIMA or front left as i keep calling it

Is my config in the correct order ?

Im using a Millenium Milo file as my basis to get started

[github.com]

So have done a fresh flash and onto my wifi network all good
Z axis direction is good and homes at top of travel and the Maxima travel downwards direction is spot on and stops at 350

The X axis on X homing travels in the wrong direction X+ in movements of 5mm everytime the home X button is pressed ?

The Y axis on Y homing travels in the wrong direction Y+ and the additional stepper (A) on the Y axis moves further than the Y stepper by double the amount at a rough guess maybe microstepping need a definition for the A drive ?

Once the second ( slow home ) home on the Z drive is done it needs to move further away from the limit stop as its still resting on it if this is an issue ? This maybe the case for all 3 axis (edited)

Mks gen L V2 Timeout error (1 reply)

RobinBonl — Tue, 26 Nov 2024 17:51:12 -0500

Dear all,

I'm trying to upload a simple arduino sketch to my mks gen L V2 board. When the compiling is done I get an error after a while. I do not know what is causing this issue. I have checked a few things:
- correct cable
- update CH340 drivers
- correct COM port (it disappears after unplugging)
- Arduino Mega board and processor selected
- hold reset button when uploading or pressing it once

Are there other things that could cause this error?
Greetings, Robin

Inquiry Regarding Marlin Firmware and Custom Stepper Motor Configuration for Circular Motion (1 reply)

hajiarab — Wed, 06 Dec 2023 14:25:23 -0500

I trust this email finds you well. My name is Mahdi, and I'm currently using the Marlin firmware for my CNC setup. I am reaching out to seek guidance on a specific aspect of stepper motor configuration within the Marlin firmware.

To provide more context, I have recently configured the Marlin firmware with five axes and four servo motors. Notably, I have two stepper motors positioned along the X-axis, designated as X and U, respectively.

My current objective is to implement circular motion on the XY plane, with the added requirement of being able to choose between stepper X and stepper U for contributing to the circular path. In practical terms, I aim to draw circles using either stepper Y and X or stepper Y and U.

I am aware of the capabilities of G-code in supporting conditional statements, but I am uncertain about the precise implementation within the Marlin firmware for this specific use case. Could you kindly provide more detailed guidance on how to achieve the desired flexibility in stepper motor selection for circular motion?

If there are specific examples, code snippets, or detailed documentation available, I would greatly appreciate being directed to those resources. Additionally, any insights or best practices related to this customization would be immensely helpful.

Thank you for your time and assistance. I look forward to your prompt response and appreciate your support in navigating this matter.

Best regards,

If statement for macro trigger in RRF (1 reply)

daninet — Sat, 18 Nov 2023 02:01:20 -0500

Hello,
I need help with syntax. I have duet 2 board with RRF.
I have a button that calls trigger2.g
So far this is ok.

I have a filament runout sensor switch connected to zstop.
Depending on the state of the sensor I either want to start filament loading or filament unloading.
So if it is triggered unload the filament, if not triggered start loading the filament. The sensor is right at the extruder so it is a good indication of which gcode to start upon button press.

How is my if statement will look like?
if sensors.???.triggered
;unload gcode
else
;load gcode
endif

Thank you

Request for Assistance: Adding 2 New Axes and Replacing Extruder Ports E0 and E1 in Marlin for a 5-Axis CNC (8 replies)

hajiarab — Thu, 12 Oct 2023 21:01:54 -0400

Subject: Request for Assistance: Adding 2 New Axes and Replacing Extruder Ports E0 and E1 in Marlin for a 5-Axis CNC

Dear Marlin Development Team,

I hope this message finds you well. I am writing to seek your guidance and support in a project I'm working on that involves customizing Marlin firmware.

I have a specific requirement to add 2 new axes to my 5-axis CNC setup and replace the extruder ports E0 and E1 on the RAMPS board. My hardware configuration consists of an Arduino Mega 2560 and a RAMPS 1.4 board.

Here are the key changes I aim to make:

1. Add 2 New Axes for a 5-Axis CNC:
- Configure Marlin to recognize and control a linear axis connected to port E0 using a TB6600 driver.
- Configure Marlin to recognize and control a rotary axis connected to port E1 using another TB6600 driver.

2. Replace Extruder Ports E0 and E1:
- Replace the existing extruder ports E0 and E1 with the newly added linear and rotary axes on the RAMPS board.

I want to emphasize that I do not intend to create a 3D printer; therefore, I do not require the extruder ports. The personal device I am creating is a 5-axis CNC machine.

I understand that this customization involves changes to the Marlin firmware, and I am eager to learn how to implement these modifications correctly.

Your expertise and guidance on how to configure Marlin for these changes would be greatly appreciated. Additionally, if there are any best practices or considerations I should be aware of while making these alterations, please do share them.

Thank you for your time and support. I look forward to your valuable insights and assistance.

Best regards,

Mahdi

Klipper Without Wifi and Changing Config Files Without Wifi (1 reply)

Westley Roberts — Sat, 26 Aug 2023 05:30:30 -0400

I just bought my first 3d printer. I'm happy I bought it, got a great bargain. The guy I bought it from was super cool. But now I need to get it working. It was working when I bought it, he was running a sample print to show me it works.

The printer is a CR-10 V3 with an skr3 board and a raspberry pi 4b 4g running klipper. Also TMC 2209's, 24V power supply, a separate power supply for the PI, a revo hotend, an upgraded extruder, and PEI flex sheet. Great starter printer for a great price, sold to me by a great guy, couldn't be happier.

But

He was using klipper via wifi. So now I must either start from scratch and reflash everything and commit to using wifi like he did, or figure out how to use it without. He gave me the config files so starting from scratch isn't horrible. BUT I'm just not OK with being forced to use wifi. I want to take my printer with me, to the cottage, to a friend's house, whatever, without needing an auxiliary computer or worrying about setting up a new network or whatever. Also I consider controlling any CNC machine via wifi to be unsafe and kinda dumb. So please don't reply with, oh, just use the wifi, I like it, it's great. If push comes to shove I will use an old laptop to run klipper, sell the PI, or smash it with a hammer out of vengeance, and then I won't need to use 2 computers, a PI, AND a PC. Sorry I'm coming across a bit hostile, LOL, I already hashed this out with some people on discord. Who, BTW did give me some advice to generally steer me in the right direction, but it was also kinda frustrating. I'm definitely not knocking the people who did their best to give me free advice though. It's all appreciated.

First off I want to attach a screen. The guy who sold it to me included a couple of Creality 12864 screens with the rotating click knob. We tried for a bit to get it to work but weren't able to, TBH I don't think we used the right configs. I know from my research that people use these with klipper, TBH I'll probably upgrade this in the future, but for now, I'd like to see what it's like to use one. Someone in the klipper discord mentioned to me that there is a 2nd partition on the micro SD cards that is formatted for linux so you can't see it in windows. Oh, and there were 2 micro SD cards, one in the PI and one in the skr3.

Also currently I can't access the printer because it's set up for his wifi network.

Question #1

Is there some kind of utility program that I can use to view and edit the linux partitions on the micro sd cards using a windows pc? As in via a plugged in USB adapter NOT wifi. My goal is to edit the config file on the micro sd(s) to use the creality 12864 screen via the exp1 and / or exp2 slots on the SKR 3.

Also potentially to edit the wifi login to my my home network solely for the purposes of trouble shooting and setup. I heard I could change this by editing the wpa_supplicant.conf file.

Question #2

The PI I have has 2 usb slots. One is used up to connect to the printer. One is free. Also the micro sd slot for the SKR 3 is accessible from the outside of the electronics bay but I'd rather use a USB. The micro SD for the PI is somewhat hidden in the bay. Does anyone have any experience or advice for how to load gcode via the USB or a micro sd slot not using wifi for a setup like this?

If I can solve #1 and #2 easily enough by accessing the linux partitions and editing the files with a text editor, then that's the best, problem solved and I never have to worry about it again. Fingers crossed!

Question #3

If anyone has any advice or experience using something other than a PI to run klipper without needing to use wifi, please free free to make a suggestion. Like an old laptop, or tiny computer, or one of the new tablets, etc.

Sorry about the rant and any help is appreciated!

How can I force an out of range move in klipper? (no replies)

leadinglights — Thu, 03 Aug 2023 11:14:06 -0400

I am not sure where this query fits in the RepRap forum, but perhaps here works. I have tried on the Klipper forum but with no luck so I am trying anywhere else that I may find Klipper-knowledgeable people.

Does anybody have any idea how to get the effector on a Delta printer to move to an area outside the printing volume? Specifically, the printing volume is a cylinder of 110mm radius by 280mm tall. I wish to be able to move the effector to X=100mm, Y=100mm, and Z about 230mm. This position seems to be achievable without overextending the delta arms but I have not found any way to do it in Klipper although I remember doing it in Repetier.

The reason I need to do this is to fit a dockable probe and have the parking dock for the sled out of the way of the printing and the delta mechanism.

Suggestions I have had, such as FORCE_MOVE only work with Cartesian printers.

Klipper on Cramps2.2: no /tmp/printer and klippy.log (1 reply)

SM180 — Fri, 21 Jul 2023 06:14:11 -0400

Hello!
I configure my Cramps2.2 with Beaglebone using this guide:
[github.com]

I used Debian 10.13 and I modified the "install-debian.sh" file adding a comment for all the lines in "step2 selection" (I attach the file).
I know Klipper has to create /tmp/printer, but it is not generate (and klippy.log is not present!)... no error during installation (I was able to flash mcu), but perhaps klipper has a problem that I can't understand....
Thanks

Issue with Eclipse build for RRF2.05.1 (no replies)

RL_berk — Tue, 06 Jun 2023 16:12:19 -0400

I am attempting to build RRF2.05.1 from Duet3D. I downloaded from the duet3 github, imported to eclipse (version 2018-09) and had some errors, worked through most of them but am stuck on one in particular. The error is line 353 of RRFLibraries/src/RTOSIface/RTOSIface.h which is the following:

static_assert(std::atomic_uint8_t::is_always_lock_free);

error is:
'is_always_lock_free' is not a member of 'std::atomic_uint8_t {aka std::atomic}'

I looked up the error and the function exists for c++17 and newer, I tried adding -std=c++17, -std=c++11, and -std=c++20 to the Cross GCC Compiler/Miscellaneous/Other flags and to Cross G++ Compiler/Miscellaneous/Other flags found in Properties/C/C++ Build/Settings/Tool Settings. I also tried freshening and rebuilding the eclipse index, and restarting. There are other errors present, but they are all make errors or recipe for target failed, and I am assuming they are because of the above described error. Thanks in advance for help.

EDIT: Uninstalled and Reinstalled. Worked fine after that.

LCD Garbage Display. (no replies)

Jarhead — Mon, 20 Mar 2023 14:39:59 -0400

Yup, another one of these....

This one is driving me crazy.
I lost my arduino, replaced with a newly flashed one, same firmware as the last, and now my LCD shows junk.
It's not interference as far as I can tell. Shielded cable, not very long and if I flash with stock 1.1.9.1 it works fine.
Once I make my changes and flash it goes nuts.
I've been through the config files over and over and can't come up with the cause.
So other than making one change and flashing, one change and flash etc, can anyone give some tips as to what changes can effect the LCD?
I can post files here if anyone will take a look at them.
Thanks.

Help with Simple Triggers for Switches (1 reply)

Techman2930 — Sun, 26 Feb 2023 13:15:17 -0500

Edi's Locker Bot Auto Mode Issue

Hi all, I need HELP!, we have a few three axes robots with a gripper that is used to move small parts to and fro.
I'm using triggers to check for switch closure. If you have an easier way of dealing with Inputs, I would be grateful.
Trigger issue, with a robot repeating a task over and over.

Duet 2 WiFi
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet
FIRMWARE_VERSION: 3.4.0
ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2022-03-15 18:58:33

See
Attached "config.g"
Attached "Edis Locker Module 1 Template 4-29-2022 Edis.g"
Trigger3.g ; set global.Auto = true
Trigger4.g ; set global.Auto = false
Trigger5.g ; Start Button RUN global.filename

While in auto mode, "global.TAuto = True", Trigger input pin Exp. Pin 9 Active Low

Auto Mode: At the end of a cycle through the G code (Edis Locker Module 1 Template 4-29-2022 Edis.g) the G code is executed again if

global.TAuto = True.
(see below)

Single Cycle: is one pass through the G Code. global.TAuto = False, Trigger input pin Exp. Pin 9 pulled high via 27K I believe.

Recently after having performed a few hundred thousand cycles across many resets, months and different parts, this robot has

decided (when in auto mode) at random times, it will stop executing G code at the end of the current cycle.

when stopped, Status is: Variable, global. TAuto = false (indicates that the Auto switch is open when it has been verified closed.)

This condition has been observed with pin nine of the expansion port connected directly to ground.

Also on a few occasions when the auto switch was turned to the single position from the auto position, the robot would continue

running from one to a few cycles of the code and then stopping without operator intervention.

This by all accounts is a random occurrence, it might stop after 10,000 pcs or 3.
Could it be that the trigger inputs are being ignored?

Am I missing something about triggers?
I observed both (Start & Auto) switch inputs with a DOscope out to 2ns/div @ 50mv/div, Not enough noise to mention.
And this condition has been observed with pin nine of the expansion port connected directly to ground.
When in Auto Mode, The Trigger input pin Exp. Pin 9 pulled down.

Nothing was changed on two robots that have this issue. :))
This issue has manifested over time which leads me toward a bad connection.
I have performed many electrical tests including changing the connector for the expansion port.

I have placed at the beginning and at the end of "Edis Locker Module 1 Template 4-29-2022 Edis.g" echo global.TAuto as well as

inserted the echo in the trigger files.
global.TAuto always tracks the switch and is very responsive to changes in the switch position.
Someone is changing the value of global.TAuto.

I placed the following at the start of "Edis Locker Module 1 Template 4-29-2022 Edis.g" thinking the M582 would check the switch just

prior to making the decision to run again.

At the end of running "Edis Locker Module 1 Template 4-29-2022 Edis.g" .

; Wait for motion to complete
M400

; Check for Auto mode.
M582 T3

; If global.Auto is true (Pin = LOW) then Run the pgm. again.
if global.TAuto = true
M32 {global.PartFilename}

Perhaps I don't understand Triggers.

Marlin 2.1 and SKR3 - will not run past heatup (1 reply)

Candidquality — Sun, 23 Oct 2022 14:02:37 -0400

Have finally passed my z issue for homing(big thanks for the help), and now have another issue.

Completely unable to run past the heatup stage.
Have my bed set to 85 to start, gets to 84.83 or some other random number just below, then sits and fails to send updates on temp to Cura. Does not run any of the startup code. Will stay hot and running even overnight, so not waiting on something slow to process. New pid tuning seems to work perfectly instead of bang bang if watching the output from Pronterface on just a heat command.

Wondering if something in the original Anycubic Mega Pro with Trigorilla 0.0.3, is no longer compatible with the new Big Tree Tech SKR3 and TMC2209 steppers?

Even when shutting off Cura and opening Pronterface, when I connect it will just keep repeating:
echo:busy: paused for user

A few caveats to mention:

No lcd yet connected(not sure of support for anycubic blue/yellow LCD) so waiting.

Stepper for the extruder not working? might be my issue if there is some kind of test.

Have made an adjustment to get rid of a m122 stepper error by including newer version of files to the stm32H7.ini file:
# ///corrected platform per issue "SKR3 EZ + TMC2209 #13" here: https://github.com/bigtreetech/SKR-3/issues/13
was; # platform = ststm32@~14.1.0
is; platform = ststm32@~15.4.1
was; # platform_packages = framework-arduinoststm32@[github.com]
is; platform_packages = framework-arduinoststm32@4.20200.220530

f_cpu is set to 400000000L in Marlin/buildroot/share/PlatformIO/boards/marlin_STM32H743Vx.json. have corrected that typo to match the cpu at "480000000L"

Anything I have changed from normal is easy to search as I have added a third /// to every section. Have attached my configs

Current startup code from my cura profile, which i have sent individually in pronterface with no issues other than my extruder not working yet. which should tell me it's working right, but unable to run a program from pronterface either. same issue, heats, then stops reporting to the interface:

Hello!
I have a generic question I don't understand. I'm building a corexy machine with duet board and rrf. The machine motion in xy direction is around 400x400mm but the bed is only 300x300. My homing is in one of the corner at 0,0. How do I define the bed (work) area? My bed starts around 50,50 and ends around 350,350. I was, ok maybe it is in the slicer, not in the printer config but I don't see such option in cura either?

Issues with custom delta printer / RRF 2.05.01 (1 reply)

Dev00 — Wed, 08 Jun 2022 14:54:06 -0400

I am experiencing very strange issue with one delta printer – based on Kossel design. It was working fine with RRF 2.05, until the bearings of the belt idler wheels got damaged. I changed the wheels as well as updated the firmware to RRF 2.05.1, but the calibration currently provides not repeatable results. It seems the diagonal length with every calibration increases ?

GTR Marlin Problems (7 replies)

Joe_E — Sat, 02 Jul 2022 22:58:35 -0400

This is my first post so I apologize if this is not the place for this or rules not followed correctly etc.

I have had trouble setting up firmware for my 3d printer with a new Bigtreetech GTR motherboard and I was hoping someone here could see what I am doing wrong. It has a 400x400x235 build volume, dual z axis (g34 enabled), all TMC2209 drivers with x/y using sensorless homing, dual extruder with mixing hotend, TFT35 E3 V3.0 touch display, bltouch (UBL 15 grid), and I plan to use a raspberry pi with octoprint through usb. I think I have these settings set up properly but I've only configured marlin for more common boards that have more help online (SKR 1.4 Turbo and a Creality Ender 3 V2 board).

It might just be that I'm doing something wrong with the display settings. From what I've seen I need ports 0 and -1 enabled for the TFT display (I don't need the marlin mode for what I want for what thats worth), but when I enable them both I get errors when compiling;

"error: 'MYSERIAL1' was not declared in this scope; did you mean 'MYSERIAL1'?"
"error: 'MYSERIAL1' was not declared in this scope; did you mean 'MYSERIAL2'?"
"error: request for member 'write' in 'multiSerial', which is of non-class type 'SerialOutputT' {aka 'int'}"

and others similar along with a bunch of yellow prompts that fail the compile. If I just have the first port as -1 it will "successfully" compile without those errors, and definitely loads A firmware onto the motherboard (sd card changes file to firmware.cur instead of bin after trying), but the display never "finds" the printer attached. So I'm hoping its just the display options I have screwed up and someone here can see the issue and set me straight quickly.

If I need to provide any further information or anything like that just let me know and I greatly appreciate any assistance.
Thanks!

Hi I'm trying to upgrade my ender6 with my coreXY kinematic, the z-stop switch is not working for me. I've rung it with a multimeter - it's set to normally closed and rings when it's not closed, and doesn't ring when it's closed, as it should, so the switch circuit isn't the problem. I have already configured the firmware via [teamgloomy.github.io] , where I set the z-switch, and disabled the bl-touch. M119 gives the same result for the z axis - that I pressed the sensor, that I did not press it - that it does not work, while the x and y axes work normally. Well, apart from the fact that I have the z-axis reversed and the table moves up instead of going down, but now I at least need to adjust this switch.

Ender 5 pro Serial communication (no replies)

miladhyt — Tue, 26 Apr 2022 08:21:39 -0400

Hello,
I have been working on Ender 5 pro where I send G-code via Serial communication also I have a dispenser where I wanna use at the desired coordination, The problem is that I do not know How I can sync these two parts, how I can get feedback from board? for example after the movement is completed the Rpi board should send a signal to the relay module which s connected to the dispenser, if I just put commands related to GPIO after G-code, since it sends codes line by line, the relay module will be turned on synced with G-code. I would be thankful to get your solution.

RepRapFirmware 3.4 with Input Shaping released (no replies)

dc42 — Fri, 01 Apr 2022 03:25:27 -0400

We recently released RepRapFirmware 3.4.0 with many new features, including these:

- Input shaping, which reduces the resonances that cause ghosting on prints, allowing better print quality at high print speeds
- Heater feedforward based on extrusion rate, which helps maintain extruder temperature when using high flow rate extruders
- The file listing in the web interface and in the file information page of PanelDue now display thumbnail images of the print (requires compatible slicer)

There are many other feature improvements, including improvements to conditional GCode expressions, the ability to use multiple outputs to control a single logical heater, and support for the EXP1HCL closed loop stepper board.

Where to get it:

- For Duet boards: [github.com]
- For SKR-based boards: [github.com]

trigorilla 2560 fan2 port does not work, fan0 and fan1 ports do work, but fans are always at 100% and the printer's display wrongly report them at 0% (2 replies)

Li — Mon, 24 Jan 2022 10:21:58 -0500

trigorilla 2560 fan2 does not work, fan0 and fan1 ports do work, but fans are always at 100% and the printer's display wrongly report them at 0%, changing them up to 100% does not set them to 0, but in the way of going up to 100, it seems that they are changing speed, so somewhat it is doing, but I'm not quite sure of what it is doing

the pin declaration to me do seem alright, I'm using the marlin 2.0 nightly bugfix version

here you can find the root of marlin under the 7zip file

Fly RRF E3 TMC2209 UART Z axis only goes up (7 replies)

Bermit — Tue, 18 Jan 2022 15:14:16 -0500

Hi,
I was testing my new own made 3D printer and I came across this weird issue. When I try to home (I'm using bltouch) or move z axis, it only goes up. I looked up related cases with same problems, but every one of them is just badly plugged cable or not having inverted the motor. I've tried everything and still no luck. Does somebody have an idea what could possibly be wrong? I've also attached my config.g file, so you can view it and see if something is wrong.

Thanks in advance.

Tevo Tornado (MKS SGEN-L V1.0) unresponsive after firmware flash. (1 reply)

tornadoproblem — Wed, 17 Nov 2021 22:18:39 -0500

I've been trying to add a Geeetech 3D Touch to my Tevo Tornado.
I flashed the printer with bugfix-2.0.x and everything went unresponsive, meaning I am no longer able to control the printer via the control box. Instructions regarding the tornado mostly cover MKS GEN-L, but not MKS SGEN-L and there isn't an example for it in the firmware. My current configuration is using #define CONFIG_EXAMPLES_DIR "Tevo/Tornado/V2 (MKS GEN-L)" and #define MOTHERBOARD BOARD_MKS_SGEN_L. (contradictory?)

Here's my current firmware: [attachment 118877 Configuration.h] & [attachment 118878 Configuration_adv.h]

I'm a complete newbie in configuring the firmware and have no idea how to proceed or what the true reason for my issue is.
My guess is that there some essential settings with the MKS GEN-L that are just wrong for the printer with an MKS SGEN-L board.

How would I go about fixing this issue?

RRF 2.x debug procedure ? (4 replies)

Dev00 — Thu, 28 Oct 2021 03:37:25 -0400

Having some issues with RRF 2.0 2.05RC1R (2019-13-03b1) for SAM4S WiFi. The firmware arbitrarily gets Emergency stop and restarts. A file simulation passes with no issues, but when begin to print, it prints few layers and Emergency stop appears.

Is there are any guide how to use the debug functionally and tackle such issues ? Any recommendations ?

Wierd issues (3 replies)

AsarianOG — Fri, 15 Oct 2021 10:17:17 -0400

So I am very new to 3d printers and like the idiot I am i purchased a used one to start with. I have a Tronxy X5SA 330x330x400 with the CXY-V6-191017 motherboard running Marlin 2.0.
Issues I have are:
1. machine only recognizes 1/4 of the printing bed. I have checked the firmware config and it is set at 330x330x400 so I am not sure why this problem is occurring.
2. while printing, in the small area it allows me too, the z axis does not seem to function properly. I start out at -5.5 and within 30 min I am back to 0 and have to end the print because it is failing. The nozzle gets completely embedding into the project at times almost as if the z axis isn't dropping quick enough. I have no clue what this could be.
Any help is appreciated or if anyone has working firmware for this machine they would share with me that would be awesome as well.

RepRap Firmware on Prusa MINI+ (1 reply)

jreinke10 — Wed, 18 Aug 2021 01:53:43 -0400

Hello,

I was wondering if anyone knows if RepRap firmware supports the dynamics of a Prusa MINI+? I have a heavily modified Prusa MINI+ that I will be putting a Duet 2 Wifi in and hope to use Reprap firmware on, but I'm unsure if it supports the mechanical configuration of the MINI (ie: I dont think its corexy, corezy, etc"). Hopefully the question makes sense!

Cheers,
JR

Fly RRF e3 Ender6 (2 replies)

crankyev — Mon, 07 Jun 2021 17:32:35 -0400

Hello, im new to 3d printing. Know nothing on g codes/firmware. issue i have just fitted a fly rrf e3 board to my ender 6, due to a damaged creality 4.3.7 board. (creality dont sell new ones, only 4.2.7, not suitable for the 6). set up with reprap firmware via their rrf config page. fitted to printer and go to home motors, get Z axis correct, press the Y axis and moves the X axis, press the X axis and moves the Y axis in the wrong direction. No matter what i do, change the motor direction in the firmware, change the wires around change the end stop homing. doesnt change anything. Do I have to add extra commands in the G code or add something to macros?.
