Please Help !!
Slight problem with Boss 6. I switched it on this morning and in setup mode
both the X and Y axis move then stop, when stopped there is a buzzing noise. I can stop the buzzing noise by switching the function switch across to restart. Then the axis move again, but stop as soon as I take my finger off the switch, and the buzzing starts again. During this time the Z axis is not moving at all. I have checked all the transistors on the Z and they are OK.

Any Ideas ??

Thanks

Dave

These are stepper machines so if a axis moves it is getting pulses in a quadrature fashion. I would suggest checking your computer power supply. DC voltage and AC ripple. If all is OK there I would check and reseat the boards.

Good luck,
