Duet2Ethernet - Phase to ground when unconnected
-
Hi,
i have a quite strange Problem right now.
I own a Predator which i rebuild nearby completly. I equipped that with a original Duet2Ethernet Board. That is running on RRF 3.4 release since a couple of time. I did set it up with an hemera Extruder.
First i used a BMG and everything ran fine. After around 2 yrs of running that extruder i did want to check if an Hemera Bowden Setup works even better. It turned out that the Hemera has issues when "hanging around" as a flying extruder.ö He don't want to have that motion on the input-side.
So i decided to give the Orbiter v1.5 a try. I printed the needed adapters etc with the Hemera. Everything worked fine so far. After changing all i did not connect the electrical lines. I started the printer and got frequently error messages about driver 3 saying "Error Driver 3 over temperature shutdown. phase A short to ground, phase B short to ground" How could that be. There is no stepper connected yet. The fan to cool the board (it's a 60mm one) works fine all the time.
I disconnected nearby all connections for Stepper and endstops to be sure that it is not a connection/cable-failure. But the error remains. I slightly get to the opinion that RRF 3.4 don't like my Duet2Ethernet or that there is a failure on the board itsself. Do you have a glue what that error message want's to tell me?

What exactly does that mean?
Does the error message go away if you connect the motor?
