E3D Roto + Duet Roto Toolboard - Stepper motor stalling
-
I'm currently using the E3D roto extruder coupled with an Duet Roto Toolboard and Duet 3 6HC. I haven't been able to print ABS in my closed chamber custom printer, after 15-20 minutes the extruder stepper motor just stops working, I have verified the extruder fan is working properly, the current for the motor is correctly set as well.
I have been using the E3D Roto for a while without issues in the same setup but recently got the Duet Roto toolboard installed. I noticed the toolboard is rated for 70C MAX but I have also seen the issue at 60C. If I let the printer cool down, I can restart the test again and again pointing to a temperature issue. Is there anything I can do?

@arturolaz there is this as well about the Roto itself

@arturolaz when it stops working, use M122 B121 to check whether the driver is reporting over-temperature, or the CPU temperature s reporting very hot. Note, the CPU temperature may need to be calibrated.

@jay_s_uk Yeah
I know I am overstressing it, I just can't get around the fact that I have used it before in the same conditions and had no issues until I included the Duet Roto toolboard@dc42 said in E3D Roto + Duet Roto Toolboard - Stepper motor stalling:

@dc42 Here is the console output for M122 B121 while the extruder stepper is failing. How can the CPU temperature can be calibrated?

@arturolaz those temperatures look OK. I'm wondering whether the grounding between the tool board and the extruder motor body may be missing. If you have a multimeter, try disconnecting the tool board connector and measuring the resistance between the VIN ground pin on the tool board and the stepper motor body. It should be 50kohms if both mounting screws are connecting.

@dc42 My bad, there is no connection between them as the way I created the fan shroud requires the mounting screw not touching the toolboard but instead coming from the shroud. I have now read the wiring notes from the docs and will be trying it.
How can this cascade to a motor stall?
-
@arturolaz extruding filament builds up static charge. If it is allowed to build up on the extruder motor body, it may flash over to the stepper motor wires. From there it flows into the stepper motor driver and may trigger the short circuit detection in the driver.

@dc42 Understood. I did the test grounding the metal body of the Roto through a wire soldered to the V- terminal of the power connector in the toolboard with a 100k serial resistor but it didn't work, it failed just like before even without reaching 70C

@dc42 I've been reading about CoolStep and I think it is the next step, unless you have another idea for me to try before.
Are there any special considerations when implementing CoolStep for the extruder? Most of the documentation is oriented for the other motors
