Re: Is it possible to enable notification after each movement of steppers? - 3 years ago
I'm not an authority on Marlin because I don't use it; however, from the source code file it looks to me that if you enable NANODLP_Z_SYNC and NANODLP_ALL_AXIS in config.h then the standard Marlin source code provides this feature.by dc42 - Firmware - Marlin
Re: PID Tuning Fails - "bad curve fit" - 3 years ago
I have replied to your similar question on the Duet3D forum. Basically, RRF has measured your heater parameters, estimated that the hot end would reach nearly 1600C if run at full power, and treated that as not reasonable. I think you will find that your manually-constructed M307 command is being rejected and RRF is using default hot end parameters for that heater, hence the severe overshoot.by dc42 - General
Re: Dual Z Issues for Ender 3 w/ Duet 2 Wifi - 3 years ago
Perhaps the two Z motors are trying to move in opposite directions, and getting stuck as a result? It will be easier for us to check your settings if you post the config.g file, homeall.g file and homez.g file. For faster responses to your questions, post at .by dc42 - Duet
Re: Is it possible to enable notification after each movement of steppers? - 3 years ago
The Marlin build for nanoDLP does that, it returns "z move compl" after each move. I'm not sure whether this is an option in the standard Marlin source code or only in a fork.by dc42 - Firmware - Marlin
Re: NEMA17 stepper motor guesses? - 3 years ago
It looks like you have an un-geared extruder. Your extruder steps/mm is probably low, maybe 100. If that's the case, upgrading the extruder motor to 0.9deg may give you more even extrusion. However, un-geared extruders need to use motors with lots of torque; and 0.9deg motors usually have somewhat lower torque than similarly-sized 1.8deg motors. My preference is to use an extruder with about 3:1by dc42 - General
Re: Ormerod 1 firmware 1.09 can't select tool - 3 years ago
You will need to either use mesh bed levelling instead (perhaps with just 4 points), or set up a bed.g file and use G32.by dc42 - Ormerod
Re: Delta Printer building - 3 years ago
PT100 needs a board, see . PT1000 doesn't.by dc42 - Delta Machines
Re: Delta Printer building - 3 years ago
See for how to connect a thermocouple to a Duet. However, unless you want to print at very high temperatures, I recommend using a PT100, PT1000 or thermistor instead.by dc42 - Delta Machines
Re: Nozzle Scraping during Travel Moves - 3 years ago
Maybe it's just slight over-extrusion then? On a delta printer Z motion is fast, so there's no real disadvantage to using Z hop.by dc42 - Delta Machines
Re: Weird problem with idler pulley - 3 years ago
Yes, the screw turns with the pulley. See section Upper Triangle at .by dc42 - Delta Machines
Re: Weird problem with idler pulley - 3 years ago
I too use idler pulleys mounted on M3 screws. However, in my case the entire screw is free to rotate, with bearings at either end. This has been working well for several years.by dc42 - Delta Machines
Re: Nozzle Scraping during Travel Moves - 3 years ago
QuoteDaHai8 However, another issue persists: On travel moves, the nozzle often scrapes the infill on travel moves. I assume that you get a good first layer, so it isn't that the delta radius is wrong. Does the problem get worse the higher the print goes? If so, one possible cause is that the towers are not exactly parallel, so that the printing plane is flat close to the bed but less flat as yby dc42 - Delta Machines
Re: Is my SSR dead? - 3 years ago
Yes it's dead. The cheap DC-DC SSRs that you find on eBay are mostly fakes. Get a genuine Auberin Instruments one, .by dc42 - Controllers
Re: Kinematic solution for belt path - 3 years ago
This and every other kinematics for which the motion of each axis is a linear combination of the movement of the motors is supported in RepRapFirmware. You can generalise it to multiple X and Y axes too.by dc42 - General
Re: Ormerod 1 firmware 1.09 can't select tool - 3 years ago
It's the RepRapFirmware.bin file at . You will need to make some changes to your config.g file, for example to add M574 commands to configure the endstop switches.by dc42 - Ormerod
Re: Deut3 Cerberus with Hermera Hot end & supervolcano upgrade - 3 years ago
You can use 12V fans or 24V fans if you power the Duet 3 with 24V. The MB6HC has six low current outputs suitable for fans. Each bank of three can be set to 12V or VIN.by dc42 - General
Re: RepRapFirmware for Duet Ethernet Frequent Disconnects of DWC - 3 years ago
Firmware 1.18.1 is quite old and normally I would recommend upgrading to either RRF 2.05.1 or RRF 3.2.2. However, Fusion 3 uses their own fork of RRF and I don't know what consequences might follow from changing to a standard build of RRF. You might be able to find someone else who has tried this if you ask on the forum at . Are you using a password on the machine? I can't think of any reason foby dc42 - Duet
Re: Deut3 Cerberus with Hermera Hot end & supervolcano upgrade - 3 years ago
The Duet 3 MB6HC has a 12V 0.8A regulator on board intended for powering fans.by dc42 - General
Re: Cracked PLA parts on Ormerod - 3 years ago
Yes, that looks like the one that I used.by dc42 - Ormerod
Re: Cracked PLA parts on Ormerod - 3 years ago
The Z motor mount crack is fairly common. There is a beefed-up design to replace it, on Thingiverse AFAIR.by dc42 - Ormerod
Re: RepRapFirmware 2.04 and 3.0beta12 released - 3 years ago
RRF 2.05 beta is very old, and beta releases are unsupported. Use 2.05.1 or 3.2.2.by dc42 - Firmware - mainstream and related support
Re: Does marlin have a function to do this? - 3 years ago
The corresponding arrangement where X needs to be compensated for movement in Y is commonly called MarkForged kinematics.by dc42 - Firmware - Marlin
Re: Does marlin have a function to do this? - 3 years ago
This sounds rather like the CoreXZ printer developed by Nicholas Seward several years ago, except that with CoreXZ the X and Z motors both affect both X and Z axes. I don't know what firmware he used but it was likely Marlin.by dc42 - Firmware - Marlin
Re: RepRap Firmware GRBL compatibility or laser optimized mode ? - 3 years ago
The standard builds of RepRapFirmware have supported laser mode for years. Use the M452 command (https://duet3d.dozuki.com/Wiki/Gcode#Section_M452_Select_Laser_DeviceMode) in config.g to switch the firmware into laser mode. Have Lightburn generate GCode that uses the S parameter of the G1 command to set the laser power.by dc42 - Firmware - mainstream and related support
Re: Scara Firmware Setup Confusion - 3 years ago
I just found a schematic of the SKR Mini and it showed a STM32F103 processor. That processor does not have hardware floating point, so it would be slow at doing the trigonometric calculations needed to run a SCARA. Have you seen the Duet 3 Mini? It costs less than our Duet 2 boards and probably has everything you need. Availability is limited at present but should get better in a couple of weekby dc42 - Polar Machines, SCARA, Robot Arms

Re: Duet wifi Vssa fuse short? - 3 years ago
When using thermistors, it's more usual to get readings of -273C on all thermistor inputs if there is a short between VSSA and one of the power rails. You would get a reading of 2000C if you configured the input for a PT1000 instead of a thermistor. More Duet help available at .by dc42 - Duet
Re: configuring smoothie firmware - 3 years ago
Quotecatmandu I have been on this project for some time now and , if I remember correctly the RepRap firmware is limited in its sizing (using a calibration tool similar to repetiers) and so was not suitable I can't think where you got that idea from. The size limits in RRF are of the order of kilometres, and always have been. BTW did you do a search to see if anyone has done a Smootheware forkby dc42 - Smoothie
