Can this be fixed ?

droftarts

it might be a hardware isssue

It hasn't been so far! How are you trying to test the motor? Are the Extrude and Retract buttons greyed out on DWC? The tool needs to be active, and the hot end has to be up to temperature. You can 'cold extrude' (ie test without filament) by sending M302 P1 (see https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m302-allow-cold-extrudes)

If that doesn't work, check the wiring of the stepper motor to the connector. Check the motor phases are in pairs, and that the pairs are next to each other when the connect to the toolboard, see https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting

@droftarts thanks ian , i can turn heater on , and im using dwc extrude . button , no signs of life , i have the wires connected correct and test phase pairs . i dont know if theres a way of get info from the driver to see if thats damaged .
or i might just have to run a wire back to the mini 5

ive been at it for 20 hours now . lol

@Richard-F Your extruder config:

; Extruders
...
M566 E2000; set maximum instantaneous speed changes (mm/min)
M203 E2000; set maximum speeds (mm/min)
M201 E1500; set accelerations (mm/s^2)

I have a Hemera (with V6, not Revo) and my extruder settings are very different. I think M566 E2000 is way too fast, and could be causing the motor to stall before it even gets a chance to move. M201 acceleration is rather high too. Have you used these values before?

Here's mine, which has been printing fine recently, albeit not very fast (mostly up to 60mm/s):

; Extruders
...
M566 E300   ; set maximum instantaneous speed changes (mm/min)
M203 E3600  ; set maximum speeds (mm/min)
M201 E600   ; set accelerations (mm/s^2)

@droftarts thanks ian , I've used your values , yes it was working fine from the mainboard , i guess the lower values give the gears less stress

droftarts

@Richard-F So it's working now?

Ian

Richard F

@droftarts no , i can put my ear next to the motor and nothing . if my gcode looks good , next ill solder stepper wires onto the tool board , no luck there ill just have to use the driver from the main board . Maybe one of the duet guys knows of a command to check driver for errors .. anyway im of to bed, I've been up all night .. Just when you think it will be a simple job lol

thanks for your help Ian

@Richard-F Check the firmware version on the mainboard and toolboard, they need to be the same. Send M122 and M122 B20 and post the responses.

Duet TOOL1LC firmware version 3.3RC2 (2021-05-11 14:59:50)

That'll be it! Upload the 1LC firmware from the 3.5.0-rc3 release. Or the zip package rc4 release to update everything to that: https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.0-rc.4

Edit: Strange that it has a later bootloader version than firmware version:
