stepper motor warning when moving up
-
I am having a problem with the z axis stepper driver issueing warning when i go up +25mm. It only moves a little bit then issues the following warning
Driver 2 warning: phase A may be disconnected, phase B may be disconnected
It appears to move down ok and without issueing warning
I have checked it's connected properly and I have checked the stepper motor (out of circuit) itself. I get 8.3 on motor 1 and 8.5 on motor 2. So that means there's no break in the wiring.
Does this mean I have some how killed the driver? It makes a high pitched noise when it moves.

Which Duet board?
How are the motors connected exactly?
What are the motor specs?
What are your settings in config.g?
What commands are you sending to move them? -
They are connected to duet 1.04b Ethernet.
I am using the stepper motor driver with the two connections. There are two motors driving the z axis. Each of them with their own cable hence I connect one motor per connector.
As for the spec am not sure because I brought the printer from prusa. The part number etched on the motor doesn't give any useful info. However it's nothing that wasn't working before I accidently shorted out the main board. Which is why am susecting a dead driver. but then again it moves downwards fine.
I have changed the config to what I had. and it seems to work now.

@ageis that warning can occur if you set the stepper motor current too high for the available voltage, especially if you are using two Z motors connected in series.

what changed? what is your psu voltage?

@Phaedrux
13v
The maximum speed and acceleration values are different from what I had in my old config.g.Now it doesn't make that high pitched noise as it struggles to move upwards.
