We have a CNC lathe with GSK928TEII controller, the X and Z drivers are not

enabled and no any alarm, the mainboard input power 24V and 5V are tested

normal, we think it is mainboard problem, the question is which part of the

mainboard could cause such situation? thanks.

Please you could test the driver Enable by grounding first, then we can confirm

if the problem comes from CNC or driver? if it is CNC problem then most

probably is IC 2803 inside the GSK928TEII is burned.
