Sudden dead stop while slewing


Peter Boreland
 

While slewing, I have recently experienced a sudden dead stop, usually about halfway to the target. Please, what might be happening here? Is it a current setting problem perhaps, or something else?

MaxESP32 Controller
TMC 5160 drivers
Slew rate 7 degrees/sec
Nema 23 motors direct worm drive.
Motor supply voltage 18VDC

Thanks,

Peter
