Hello
I have just completed a medium sized hobby CNC mill. It is arduino uno based connected via breakout board to the motor drivers, these are TB6600, stepper motors are Nema 23HS2430B rated 3 amp, power supply is 36 volt 16 amp.
I am trying a very simple oval cut, the that the first straight cut completes, the 180 degree at the end completes, the next straight cut completes but the final 180 degree only completes to 90 degrees then the cut is just straight as the X axis has stopped. I have tried other operations but the X axis will drop out. If I cut the power to the stepper driver the X axis will resume. I have reloaded grbl, also changed the arduino board and the stepper drivers. I am just running the machine without any work piece so there is no undue resistance on the motors. This is the gcode that I am running

Is there something in here that would cause this error?
Thanks for any help
