I think it is related to this thread:

thanks for this exquisit thread, helped me fix this shit, too.

I thank all of you for your answers.

Wouldn't it be better to define the motor current per driver for future firmware versions?

@dhusolo I have 4 z steppers on the duet 3, due to the lack of a 7th driver, I wired one motor to driver 4, one to driver 5 and two to driver 3.

I am searching a way to define different currents for one axis in M906.

Thanks for the reply

@Phaedrux hi,

I am running a Duet 3 with two z motors on driver 3. One motor on driver 4 and one on driver 5. I tried to set different motor currrents, since driver 3 has to drive two motors. I stumbled upon the fact that the M906 sets motor current per axis instead of per driver, what would make way more sense to me. Is there a way to set different currents for one driver?

Thanks by the way.

Hi, today I ran into the issue, maybe it's a non-issue, maybe it's real.

I tried a setup where I have three drivers for a z axis. One has the glorious job to drive two drivers, the other two drivers wotk single motors.

My question is about defining M906 so I can have different currents for these different drivers?

Second, why is M906 based on axis instead of being driver based? If I missed something, it's ok to tell me, too.

e than one fan output isn't working, either the fuse ble

Thanks man.

@appjaws I have an Anycubic Predator here it uses a combined positive wire for both part cooling and hot end fan and it uses separate negative wires, so "furtuanitly"/s two of my three ports have been fried. My guess, since it happened midprint is, that the hotend fan is shorted. Thanks

@dc42 Thanks for the reply. Is there more information on the repair part (changing the mosfet, not the fuse, this exchange I am able to perform). Is there an e3d repair service for these cases?

Today I came to my printer (Duet 2 Wifi controlled) and it had it's Bowden-Tube popped out.

Trying to start the print again after poking the nozzle, made me realise the hotend fan was not spinning.
I tried another fan directly plugged in to the board and it didn't spin, either.
So I figured (BIG MISTAKE) pop in my experimental board and try this one.
Plugged everything in, tried the before mentioned fan, everything was working.
I switched to the hotend fan (BIG MISTAKE) and switched the machine on and I heard a sparking sound.

TL:DR I had a bad fan kill two of my boards,
I want protection against something like that in the future.

Thanks and press 'F' for two dead loved ones.

@deckingman just checked the gcode since I changed to reprap in my slicer, the M203 Z420 replaced the M203 Z7 that was previously inserted.

Awesome support.

@deckingman since 4.1 Cura came with the option to set "maximum z speed" by default it's 0 and it causes a lot of pausing while z hopping and stuff.

So again it's my fault for not changing from marlin to reprap after switching from the crappy anycubic firmware to the duet board.

Thanks a lot for making this clear to me. Sorry.

@deckingman i think than I will have to change thus cura as well, might be the problem, since cura sets M203 Z7, which would result in a problem.

@deckingman thanks again, I thought, that the both had better interchangeablility.

@phaedrux thanks man, it's a delta.

@deckingman Thanks man, I went with M203 X5000 Y5000 Z5000 and G1 Z5 F5000. Now I can live with the speed. I am not sure what's causing this, cause I read on the marlin website, that M203 is in units/second underneath the description there, the example said mm/s.

Changing G1 Z5 Fnn didn't gave any result.

For now I will keep it that way.

Thanks again.

@deckingman Thanks for your response.

But even if I add M203 Z50 and
G1 Z5 F600 the movement speed remains at 1mm/s and I have no idea where this is coming from.

Hi,

when I pause a print, the z speed turns to 1 mm/s, can't find anyplace this is taken from.

; pause.g
; called when a print from SD card is paused

M83 ; relative extruder moves
G1 E-10 F3600 ; retract 10mm of filament
G91 ; relative positioning
G1 Z5 ; lift Z by 5mm
G90 ; absolute positioning
G1 X0 Y0 ; go to X=0 Y=0

This is my pause.g

; stop.g
; called when a print is cancelled after a pause.
M104 S0 ; cool down nozzle
M140 S0 ; cool down bed
;G28 ; home all
M107 ; turn off fan

This is my cancel.g

Thanks
