Re: Mini differential IR height sensor board - 23 days ago
Yes, if you add an external resistor.by dc42 - For Sale
Re: Mini differential IR height sensor board - 24 days ago
You can tell whether the sensor has started up in analog or digital mode by counting the number of LED flashes after power up. See the instructions at .by dc42 - For Sale
Re: Mini differential IR height sensor board - 24 days ago
If the sensor doesn't detect a pullup resistor to +3.3V or +5V then it operates in pseudo-analog mode, outputting 4 different voltages depending on whether it is a long way from the bed, close to the bed but not quite triggered, close enough to be triggered, or overloaded with ambient light. If the board it is connected to treats the input as digital then it might see the "close to the bed but noby dc42 - For Sale
Re: Help with Config Upgrade 1.21 -> 3.3 
- 7 weeks ago
Hi @qunie, for faster response I suggest you start a thread at where the RepRapFirmware community and our support engineers will be please to help you. I took a quick look at your config files. For the BLTouch you used to have this M558 line: M558 P9 H5 F120 T6000 ; Set Z probe type to bltouch and the dive height + speeds You now have this one: M558 P1 C"zprobe.in" H5 F1by dc42 - General
Re: How to set custom home position and drive directions - 8 weeks ago
Please post the whole config.g file, in particular we need to see the M574 commands that configure the endstops. You can test the endstops, either by enabling and opening the Object Model Browser in the Web interface and expanding the "sensors" key, or using the M119 command.

Re: How to set custom home position and drive directions - 8 weeks ago
@oBezruki when you say RepRap do you mean you are running RepRapFirmware, or are you actually running Marlin? If you are running RepRapFirmware then please post your config.g and homing files.by dc42 - Reprappers
Re: best post processing method to get smooth prints - 2 months ago
Likely out of your price range, but the E3D tool changer has an option called ASMBL which uses a small milling tool to do the finishing of the print.by dc42 - General

Have you seen the Smart Effector? It uses a built-in strain gauge to detect nozzle contact.by dc42 - Tech-Talk
Re: Help with Simple Triggers for Switches - 3 months ago
Hi Techman2930, please post on where our support staff and the RepRapFirmware community will be pleased to help you. It may help if you post a M122 diagnostic report taken after the fault has occurred and before you power down or otherwise reset the Duet.by dc42 - Firmware - mainstream and related support
Re: Delta calibration point triggering (way) before reaching the bed - 3 months ago
I agree with your diagnosis. What sort of rod end joints are you using? Perhaps one of the joints between the effector and the Z tower rods is hitting its limit and stressing the effector and then the piezo module.by dc42 - Delta Machines
Re: What to Build Next - 3 months ago
Vorons are also built with Duet electronics and RepRapFirmware. No need for a Raspberry Pi.by dc42 - General
Re: Core ZXZY Build Log - 4 months ago
Looks interesting! As the kinematics is linear, RepRapFirmware supports it already, without even having to recompile.by dc42 - Reprappers
Re: Kossel, Z-Height if Calibration Cube is way too small - 4 months ago
Rod length only scales X and Y. Z scale is determined by the steps/mm setting of the tower motor drivers. Get the Z scaling right before you adjust the XY scaling.by dc42 - Delta Machines

Re: Establish a "Firmware - Klipper" folder in "Firmware Folder" - 6 months ago
If a Klipper firmware folder is added then a RepRapFirmware folder should be added too. However, most Klipper support seems to happen on Discord, and most RRF support happens on the Duet 3D forum for Duet boards, and on the same forum or on Discord for STM boards.by dc42 - General
Re: FEED HOLD - 6 months ago
You can get a reasonable approximation of feed hold by enabling segmentation in RepRapFirmware using the M669 command. True feed hold on planned for version 3.5 of RRF.by dc42 - General New Machines Topics
Re: Duet2 WiFi V1.04 - 6 months ago
The board will only connect to Bossa if you first erase the firmware, by placing a jumper across the Erase pins. Remove the jumper before you use Bossa to program the board. The command M552 S0 does not connect to WiFi, it merely puts the WiFi module in Idle mode. You can then use M557 to program the SSID and password. See .

Re: Duet2 WiFi V1.04 - 6 months ago
This page describes the structure and files you need on the SD card. You can get the firmware and network files from the latest release in and you can generate the configuration files for your machine using the configuration tool at . If the firmware has been erased then you can reinstall it using Bossa, see . HTH Davidby dc42 - Duet
Re: reprap full discount graphics controller gets garbled sollution ? - 6 months ago
It's well known that attaching a graphical LCD overloads the 5V regulator on the Arduino, causing it to overheat, reduce its output voltage, and often fail. Connecting USB provides an alternative source of 5V power. 12864 display modules vary in the back-light current they draw. Some have a zero ohm back-light resistor fitted.by dc42 - General
Re: Elephant Foot on slic3r ?? - 6 months ago
It's likely that your Z homing isn't quite right or your Z probe trigger height is configured too high, so that the nozzle is a little too low when the first layer is printed. It could also be that you are Z homing and probing correctly but doing it when the bed and hot end are cold, and when they have heated up the distance between the nozzle and the bed decreases because of thermal expansion.by dc42 - Slic3r

Re: Edit Marlin for Polar Coordinates - 7 months ago
Marlin is not the only firmware. RepRapFirmware supports polar printers natively. You don't even need to recompile it. It runs on 32-bit boards such as a Duet and good STM-based boards.by dc42 - Developers
Re: Maybe the World's Lightest Extruder - 8 months ago
Quotearsi But the main problem, which appears with all knife shapes, I have not yet managed to eliminate. The pressure on the filament from the hotend, causes a change in the thread pitch at different speeds of extrusion and therefore the number of steps per millimeter. According to this video, I'm not alone This is why RepRapFirmware supports nonlinear extrusion, to allow for the extruder steby dc42 - Tech-Talk
Re: Ender 6 COREXY issue in Marlin - 9 months ago
Glad to help. This is a fairly common issue with CoreXY machines. With the motor connections one way round you can only get left hand coordinate systems, and with them swapped over you get right hand coordinate systems. Changing the direction of one or both motors does not change the handedness.by dc42 - CoreXY Machines
Re: Ender 6 COREXY issue in Marlin - 9 months ago
Swap the X and Y (or A and B if that's what you call them on your machine) motor connections. Then adjust motor directions as needed.by dc42 - CoreXY Machines

Re: Extending cable for paneldue - 10 months ago
You can use a 4 wire cables up to at least 2m long with PanelDue. If you really do have comms with both PanelDue and Arduino working off the same port, you could connect both cables to the 4-pin connector.by dc42 - Duet
Re: Extending cable for paneldue - 10 months ago
The 4-pin connector and the ribbon cable connector use the same transmit and receive signals. So you can't use both connectors for different communication. You may be able to pass the PanelDue signals through the Arduino, as we do when connecting a CNC pendant. Alternatively, can you use I2C to communicate with the Arduino instead?

Re: DUET2 WIFI AND REVO VORON - 10 months ago
