Stepper motors and thermistors not working
-
I recently just bought the Duet Wifi 2 and seem to running into issues. On all of my drive motors, I am getting an error when I try to home any of my axes.
Warning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2I have checked to make sure the motors are wired correctly using a multi meter and I am reasonably sure the crimps are good.
Along with that all of my thermistors say they are at 2000C. The thermistors are from E3D so firmwaire configuration should have been simple, and I am reasonably sure they are plugged into the right spots with good connections.
Any ideas?

@Pslayback update your firmware. You’re running firmware 2.03, but your config is for firmware 3. You need to update to 3.0 first, then 3.1.1, which is the latest.
The driver reporting the error is the Z axis. You may be getting this error because your Z steps per mm are 4000, and you’re trying to move the motor too fast. I suspect 4000 is the wrong value for your Z. What is the pitch of your Z leadscrew?

From the web interface, upload the following zip files to the /sys folder. This should trigger a firmware update and update the DWC files as well.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip
Once you've updated all 3 you should send M115 to verify that you're on 3.1.1. Then send M98 P"config.g" to see if any errors are generated from your config.g and report them here for further troubleshooting.
-
Thank you both! The firmware seems to have fixed the Thermistors, but not the steppers. The leadscrew is M5 and I think it is .8mm pitch. I am not certain though, is there an easy way to tell?
Also the M98 command returned this
M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C -
@Pslayback said in Stepper motors and thermistors not working:
The leadscrew is M5 and I think it is .8mm pitch.
In that case 4000 would actually be correct.
That M98 command shows no config syntax errors so that's good.
Are you using dual Z motors or just a single? If just a single, do you have the jumpers installed on the unused z motor pins?
If you're sure the motor phases are correct you can try to remap the Z driver to another driver to see if the error follows to the new driver. Vice versa you can try a different motor on that driver to see if you get the same errors. This will let us determine if the problem is a failed driver chip.
Also you can post a close up well lit photo of the drive chip.
-
Currently none of the motors (x,y nor z) are working. I am using just one motor on the Z axis, and i have not put the jumpers on.
-
That would likely be the problem then. Install the jumpers on the second z motor connector.
-
I attached the jumpers, then tried homing the X axis, which then the z axis moved (yes I double checked wiring). Then the board stopped doing anything. It will not even power on.....I think I tripped a breaker???
-
Please post your homing files.
Z movement when homing the other axis is normal because there is likely a small z movement to lift the head out of the way for X Y movement.
Check for shorts.

-
Yes there is a Z move at the start of your homing files

Are you getting any lights on the board at all now?

-
Ok, that makes sense. If plug in an external power supply the red lights come on, but not the green ones. I disconnected end stops, but still nothing, any ideas?
-
Disconnect everything and take the board out if you haven't already and post some close up well lit shots of the board so we can maybe spot any damaged components.
Then move on to connecting it to a PC via USB to see if it shows up as a bossa port
-
The board is showing up to the computer correctly and here are some pictures
-
Ok, turned out it was a power supply issue and was able to fix that. Now the problem is only the z axis will move, still no x or y movement.
-
Not much to see except maybe this
The 3.3v led is lit, but maybe you could measure the voltage of a 3.3v pin just to check its all good?
-
Can you get a better photo of U2?
Also it appears you have a clone Duet.
For X and Y, how are you trying to move them? Do you get any error messages? Are you sure you've wired the motor phases correctly? If you move the Z motor to the X or Y driver does it work?
-
I am no longer getting any error messages, I tested the phases with a multimeter and they should be wired correctly. The y axis moves a little but not much, I am still not getting any x movement, and the Z is only moving up when I try to home it. When I switched the z and y motors then moved it, the y axis (z motor) did move.
