Gero, it looks like you’re testing v1.02 of the firmware, yes? I had a problem with step 2 of the calibration sequence - the left motor wants to turn 240 degrees instead of 1 degree. The right motor behaves correctly. Does this happen on your setup, or is it just mine?
Never mind, the issue was caused by a loose connection on the motor end of the cable, maybe one of the encoder signals.
I am having the same issue you had recently, but nothing I try is working. OS: windows 10 FW:1.06 GC:1.06
I have checked my connections and power - everything seems to be ok. I do not get a response from the motors when I test them, and trying the manual chain calibration does nothing. Any thoughts? Thanks for any help you can provide.
I’m sure you checked the power is in the motor shield and not in the Arduino.
How did the firmware upload go? Any error messages?
On what port does the Arduino IDE connect to. Is that port set in GroundControl?
