It's very rare for the heater mosfets to fail, so I suspect a firmware or configuration issue. Try reinstalling firmware using Bossa. You might like to try more recent firmware. The latest firmware for your board is version 1.26. If you do upgrade the firmware, you will also need to update the web files on the SD card, and make some changes to your config.g file.by dc42 - Ormerod
I agree, the most likely explanation is a bad connection somewhere. Most likely a crimp connection, but I once saw and instance of one of the pins of the motor connector not being properly soldered to the PCB. Also possible, but unlikely, is a bad solder joint between the driver chip and the PCB. Are you using all 5 drivers? If not then you could rule out the driver by reassigning that motor toby dc42 - CoreXY Machines
Have you lubricated the magnetic joints? I use a little silicone grease.by dc42 - Delta Machines
QuoteDust neopixel's are the absolute worst when it comes to 3d printers A 3d printer requires very precise timing in order to print nicely without 'zits' blogs etc. Neopixles also require very precise timing. If you add to many Neopixel it will interfere with 3d printing. That's true if you bit-bang them. On Duet 3 we use an SPI peripheral and DMA to drive them without interfering with the prby dc42 - Firmware - Marlin
You can add WiFi using a nano router such as the TP-Link WR802. Although Duet Web Control doesn't currently display the duration of the last print, if running firmware 3.1.1 you can retrieve it from the object model. It's called "job.lastDuration". So you can send: echo job.lastDuration and the time in seconds will be echoed to the command line. A slightly more sophisticated way is to put theby dc42 - Duet
It's a question of whether you prefer mechanical complexity or electrical complexity. If you are more comfortable with mechanics, you will prefer a single Z motor driving all 3 leadscrews with a closed loop belt, and bed levelling screws to get the bed level. If the frame is sturdy and rigid enough, once levelled it should stay levelled. OTOH if you are more comfortable with electrical complexityby dc42 - CoreXY Machines

Quotejbernardis I was planning on swapping out the fans and the extruder heat cartridge for 24 volt versions, and the bed has an alternate connection configuration for 24 volts. At first glance, this would tell me that the 15 amp 24v PSU is fine, except that I would guess that the bed draw does not halve. It probably will continue to draw 11 amps at 24 volts which won't leave enough for the othby dc42 - Smoothie
Yes you can run a 12V 40W heater from an extruder heater output on the Maestro. Use the screw terminal connector which is rated at 5A, not the 2-pin Molex connector which is rated at 2A.by dc42 - Duet
I think there is a mechanical problem with one of the arm joints, most likely an arm on the right hand side of the height map; or with a bed probing contact on the left hand side.by dc42 - Fisher

QuoteChemaFuji Hi all again! I have a mystery on my setup, from installing the v3.1.0 the machine is not able to make the height map file. I run the G32 correctly, then try the G29 and it goes to everyone point to measure, but when it finishes, no heightmap.csv file nowhere... Initially, my mind was the file is corrupted or read-only or... so I deleted it, no luck. The strange thing is that afteby dc42 - Firmware - experimental, borrowed, and future
Thanks for pointing out the error in my post, which I have now corrected. It's actually the other way round: the specification says M203 takes mm/min (like the F parameter in G1 commands) but PrusaSlicer generates mm/sec.by dc42 - Ormerod
Most likely the wire between OUT on the IR sensor and the IN pin on the Duet Z probe connector has broken.by dc42 - CoreXY Machines
If you set the profile in PrusaSlicer to RepRapFirmware then I think it should be OK. Otherwise, PrusaSlicer tends to put M203 commands in the generated GCode file. Even though M203 has be defined to expect values in mm/min for the last six years, Prusa Slicer puts mm/sec values in the M203 commands that it generates. Hence the very slow movements.by dc42 - Ormerod
QuotePeterSimpson The presence of the G92 Z0 in my homez.g file was wrong in that it was setting the position after leaving the G30 command (i.e. the trigger height + 5mm) as Z=0! After removing the G90 Z0 command it now works as it should, and G1 Z0 moves the head to just touching the bed. That's exactly right. I'm glad you sorted it.by dc42 - Ormerod
Yes you can keep your existing stepper motors. All 3D printer control boards use constant current drivers.by dc42 - General
Quotejay_s There was someone that DC42 knows who was supposed to be working on just that. Not heard anything about it for a few months though. @DC42 any update on the STM32 port? I've seen nothing since this [3dtoday.ru].by dc42 - Firmware - experimental, borrowed, and future
There was a version 1.24 update to PanelDue firmware recently, but it's only needed for systems using an attached SBC. It surprised me that quite a few users with Duet 3 + SBC want to connect a PanelDue too.by dc42 - Firmware - experimental, borrowed, and future
It's unlikely that the mosfet has failed unless there has been a short circuit. Most likely it's a bad crimp connection or a failed connector. Unplug both ends of the heater wires in the hot end cable, also the heater where it plugs into the hot end board, and look for signs of burning or bad connections.by dc42 - Ormerod
Why can't you use the online configurator? To reflash the firmware, see .by dc42 - Ormerod
The latest firmware for your Duet 0.6 board is version 1.26.1 available at . You will need to make some changes to your config.g file when you upgrade, otherwise homing switches may not work and the X axis may move the wrong way. You can use the online configurator at reprapfirmware.org to generate new config.g and homing files.by dc42 - Ormerod
Quotesdavi For those waiting for the non-paneldue UART mode in RRF3 to use TFT32, ESP3D, etc etc, these should hopefully be working again as of 3.01-RC11 as DC42 has just implemented UART "raw" mode. I've just done some testing with 3.01RC11 on the LPC port and is working well for me. This replaces the need for the old "lpc.uartPanelDueMode" board.txt setting that was used in LPC-RRF2.

Have you tried pressure advance? It's normal to get under-extrusion immediately after a travel move and over-extrusion immediately before one unless you take precautions to avoid it, of which pressure advance is usually the most effective.by dc42 - Printing
Extrusion in RRF is always relative, apart from the "Virtual extruder position" which is used to handle GCode files sliced in absolute extrusion mode. So I think you need to accumulate the extrusion done on each print, and reset the accumulator when you reset the syringe. However, the "rawExtruderPosition" doesn't take account of changes to the extrusion factor using M221. For faster response, Iby dc42 - General

Quoteosterac I haven't been able to get the USB LED to light up. That implies that you haven't soldered either the ground or the +5V wire of the USB cable to the correct place.
