@T3P3Tony I will recheck if G10 works on tuesday.
Its a error beeing generated by the Silyer (SuperSlicer) and it shows on a new opened error window on trying to slice.
I guess its a problem on using the "[next_extruder]" varialbe on a print that uses just one tool (and there is no "next extruder".
I didnt cross check it, but I think that also Slic3r and PrusaSlicer will have the same problem.
Knowing the inductance of the motor won't help making it faster.
I'll soon test external TMC2225 drivers which are suitable for 36V and 1.4A. Just right for those geared extruder motors (or my hitchhiker IDEX motor)
Most external driver boards have 35V capacitors and separate Vin...
So just to confirm I need to take the updated firmware files from one of the two links you just sent me (really not sure which - hope you will clarify that) - the updated versions of those you show I need in the /firmware folder from this pic in your previous post:
Also please NB your instructions to install 3HC first differ from before. Can I confirm that’t the way I should do it from DWC?
Check with M115 from that. It should be version 3.3. If its not the send M997 to up grade the firmware on the mainboard
Once the mainboard is reporting version 3.3 then send M115 B1 to find out what firmware is on the expansion board. It should also be 3.3 but may not be. Send M997 B1 to upgrade it to 3.3. Once both the main board and expansion board have 3.3 firmware on them (verify by using M115 and M115 B1) we can move to the next step.
SerialTools is a bit finicky about input; you have to get the command right, without pressing delete or cursor keys. I think it sends each character to the Duet as you type them, rather than when you press return. If you navigate away from SerialTools to another application, and then back, in the middle of writing the command, it won't work. You should get an 'ok' when a command goes through correctly.
Also, make sure you're using straight quotes, eg " rather than curly quotes, eg ”
@palmhoej it si worth checking the wiring bit I don't think its a totally failed wire as there is more movement than i would expect if a phase was completely disconnected. Are you getting any warnings in DWC console when you move the motors.
Swap the two Z motor connectors to see if the problem follows the motor/wiring or the dirver.
@medicusdkfz if possible can you upload a (short) print example where you got the issues with relative E distances and that then is fixed with absolute? In general the normal advice is to use relative extrusion not absolute extrusion because it prevents a build up of errors in rounding, however this will help my investigation into what's happening.
