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 https://duet3d.dozuki.com/Wiki/Gcode says this: M575: Set serial comms parameters ... Snnn Mode: 0 (default in RRF 3 for Duet 3) = disabled; 1 (default for Duet 2) = PanelDue mode, checksum required; 2= raw mode (supported only in RRF 3.0beta13 and later) This is incorrect? Yes it's incorrect. I have updated it. It will probably be one of the first things to be implemented in the 3by dc42 - Duet
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. Quoteosterac If raw mode is supported in 3.02, does that mean I can use a beta firmware to turn on raw mode? 3.02 isn't in beta yet, we're currently finishing off 3.01.by dc42 - Duet
Quotedlc60 Can the Duet Maestro controller hardware/software, level a bed by moving each stepper (side) independently to its respective zero end-stop? Yes, using either separate endstops or alternatively just the Z probe.by dc42 - CoreXY Machines
I found that the secret of printing PLA on bare glass is to wash it initially in hot soapy water, rinse, dry it with a paper towel only, then avoid finger marking it. Before each print, wipe it with a little distilled malt vinegar. Do not use isopropanol, acetone or other organic solvents.by dc42 - Printing
If you really are running version 1.10 firmware, that's several years old. If you want to upgrade it, I suggest you seek advice at for a faster response. I think changing the bed heater to PID control may solve the problem.by dc42 - Printing
I guess it's possible that you fried the port, although IMO it is unlikely. Does the USB power LED light up when you apply USB power? Are you sure you have connected the Data+ and Data- wires the right way round? Currently the PanelDue port always uses PanelDue protocol, which means that responses are returned inside the JSON response to M308. So it would need a firmware change to return the resby dc42 - Duet
What M305 commands do you have in config.g ?by dc42 - Ormerod
QuoteStuartMoorhouse Could this be something to do with both the extruder and bed being at higher temperatures and each time the bed kicks in we see a change in power to the extruder heater? Yes, that's one mechanism that causes extrusion to depend on whether the bed is on or off, although in RepRapFirmware that is compensated if the extruder heater has been tuned. The other mechanism is bucklinby dc42 - Printing
On my Ormerod I used to print PLA at 195C for the first layer, 190C for subsequent layers, and 60 or 65C indicated bed temperature. Retraction was 4mm.by dc42 - Printing
Are the side-to-side undulations on the left hand edge in phase with those on the right hand edge (i.e. layers are shifting sideways and back again), or out of phase (i.e. layers are expanding and contracting)? If layers are expanding and contracting, check the following: - Layer height is a whole number of full steps of the stepper motors - Bed heat is using PID, not bang-bangby dc42 - Printing
The easiest option is probably to cut the end off a micro USB cable and solder the wire ends directly to the correct points on the Duet. It doesn't matter if the USB connector pads are gone because there are other points you can solder them to. Someone reported doing this successfully recently on the Duet3D forum.by dc42 - Duet
Use M563 to create a single tool that uses both heaters and both extruders. That way you don't need to switch tools.by dc42 - Firmware - mainstream and related support
Yes, you can create a single tool that uses both heaters and both extruders (same as when ditto or mirror prints on an IDEX printer) and send a single GCode line to drive both of them.by dc42 - Firmware - mainstream and related support
We tried a laser sensor too, but there are some filaments that it just doesn't work with. We found it more reliable to use the filament to turn a shaft and measure the motion magnetically, so we made this . As with the laser monitor, the firmware correlates measured extrusion with commanded extrusion so it doesn't only detect complete jams.by dc42 - General
I don't think that would be possible to implement without a severe impact on print quality, because of the shared Y axis. It would also need a very clever slicer to generate GCode to print two objects with a shared Y axis. RepRapFirmware supports multiple Y axes as well as multiple X axes (that is, IDEXY as well as IDEX) and at least one user is running such a machine on Duet electronics. With iby dc42 - Firmware - mainstream and related support
If your printer is running RepRapFirmware, test that the motor for that tower works in both directions. See . If it will go down but not up then only one of the phases of that motor is being energised. Likely causes are a bad crimp connection between the wire and the connector, or a failed driver.by dc42 - Delta Machines
Which Duet is is it? Duet WiFi/Ethernet revision 1.03 and later have a 1A blade fuse for the fan supply.by dc42 - Delta Machines

QuotePower3DPrinting Also hi DC42, still selling those IR sensors? Really cool to still see you on the forums. Thanks! I recently handed over production of IR sensors and PanelDue to Duet3D Limited. I don't have time to do production management and testing any more because of all the work I do on RepRapFirmware and new hardware development these days.by dc42 - General
Those motors need more than 12V to get good performance out of them. Either upgrade your machine to 24V power (which isn't straightforward with RAMPS) or replace the motors. The axis motors may have the same issue.by dc42 - General
