@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.

@fcwilt
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...

@wurth51 if you get a short between Vssa and a higher voltage then you should get a message on the DWC console warning you of the short.

@jrdm I designed and printed one. Works surprisingly well.

@t3p3tony Sorry it took so long to reply to you Tony, yes that worked for manually moving all of the axis to the endstop but now none of them move at all when being homed in DWC

@T3P3Tony

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.

@t3p3tony
Yes it gets really hot via USB and it looks like only the cpu is getting hot.

@dan1990 thanks for confirming what the issue was.

@themonet Looks like you used M552 SO, with an upper case 'o' not '0' ie zero.

See this thread about someone having issues with SerialTools: https://forum.duet3d.com/topic/23545/mini5-wifi-set-up

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 ”

@t3p3tony
Fantastic : ) thanks for clarifying that! I misunderstood the instructions and thought everything out of the toolboard was at 12v, unless the jumper was used to select 24v.

@t3p3tony I try that Monday, and yes the command to move the bl don't work after print

@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.

I've now got it working straight to the laptop via ethernet.

I think it might be some settings in my router causing the connection issue

@jay_s_uk So, everything above 100000Ω I guess? Anyway, thanks for the quick answer.

@t3p3tony Thank you. Just emailed them with a link to this thread. Thank you for responding so promptly. Larry

@jay_s_uk said in Cannot get hot end heater to work after change to RR3:

M950 H1 C"e0heat" T1

You bloody star - excellent. That worked.

Thank you.

@droftarts ok thanks for the help.

@j3dk the crimp tool I recommend for these is the Engineer PA21.

@dhusolo as @jay_s_uk says thats not possible those IOs work at 5V and can only source/sink a few mA.

There should be no issue running both part cooling fans from out 1 or out 2 at 24V in parallel (obviously with the jumper set for VIN and 24V supplied to the toolboard)
