@Stan said in DWC 3.5.0-rc.1 disconnects after a while:

Y is 3400mA (dual Y motors)

If you're using a Duet 2, the motor current is probably just set to max, ie 2.5A.

Are your motors wired in parallel? I'd guess they are if you have doubled the motor current. However, due to the current limit of the Duet 2 drivers, they are only getting 1.25A each. If they are wired in series, the voltage is doubled rather than the current, which the stepper driver can do itself. You would potentially lose top speed, but the controller would run a lot cooler.

final update:
I had my organization purchase a new Ethernet module off of ebay, installed said module and everything is running as expected again.
Many thanks for all your help 🙂
