Could you specify the power source you are using?
XL430 requires DC 12V power supply in order to operate properly.
Thank you for your answer. We are using one of the TTL sockets of the OpenCR to power the motor, could that be the problem?
In that case, OpenCR1.0 will also try to respond to the signal from R+Manager and could cause such issue.
Please try to supply power only from OpenCR1.0 by pulling out the Data pin from the cable.
Just a small note: we won't be able to test the suggested solution until early April, but please do not close this issue due to lack of answers from our side. We will reply back again in a couple of weeks.
