Hi,
I am working on a ProBotix V90, with Probotix 3 Axis Sidestep bi-polar drivers, running 280 oz in steppers, 4-wires. I am using EMC2 software and cutting the test pattern logo that is default with the software. My machine has begun missing steps both when I jog the axis, and when it runs the program. Any help troubleshooting this issue would be appreciated. Thanks.
