Extruder not spinning properly?
-
@oscorp said in Extruder not spinning properly?:
started smoking after about 4 minutes
What part exactly was smoking?
-
@phaedrux it was the pancake motor for the extruded assembly. So I ordered an entire new assembly with new motor and the new one is doing the same non spinning issue which means it must do with the firmware change. Maybe the motor is mapped wrong or the amps. I’m not sure
-
Remap the extruder driver as another axis and see if it still has issues. I think you have damaged a driver.
-
What specifically would I change in my config.g to change that?
-
Driver mapping is done with M584
M584 X0 Y1 E3 Z6:5:8:7So you'd want to change one of the other axis, such as X to use driver 3 then connect the x motor to driver 3 and then test it's function. If it still has problems then driver 3 is damaged and it's not a firmware/config issue.
As for what happened to cause the damage, I'm not sure. I'm not familiar with the Troodon board at all.

Here is the X-axis trying to home after being plugged into motor drive 3 on the mobo and being remapped in the config.g
Is that indicative of a blown drive motor on the mobo? -
It certainly doesn't seem to working.
Have you done a visual inspection of the driver chip? Does the chip get hot?
Do you have an unused spare driver?
-
I don't. What exactly is it that I would need to replace on the mobo? Sorry I'm still new to working on 3-d printers.
-
Well as this isn't an actual Duet product and I'm not really familiar with the Troodon boards I can't really venture to say what to replace. The board maker would be the better place to ask. Just speculating you might be able to replace the driver chip if you have that kind of hot air rework capability.
