Strike CNC (My first CNC router)

[Gary]

Set the current to either 3.6 or 4.6A, but start at 3.6A peak.
see if this solves the noise problem?
Regarding the software problem, this could be noise? make sure the RS232 cable is away from any power cables, and also make sure that your signal cables (Step, direction and enable) are well away from any power cables like the motor and the power supply cables. I cant see in the picture if you have done this. Also are the motor power cables shielded? and grounded at one end?

Thanks for the help.

The stepper cables are shielded and ground at the control box end.

I'll try changing the current to what you suggest. The motors still made the same noise with the default setting of 1A before I changed it to 3.93A so no damage done to the motors.

Will play around some more this afternoon based on whst you've suggested.

OK, make sure that the rotary switch is in the "0" position.
Set the current to 3.6A and then power up.
Then move SW4 on and off twice to get the driver to tune to the motor specs.
Once this is done it should work ok.
Make sure the signal cables are not close to any power cables.
When you power the driers up, did the inverter for the spindle power up? if so disconnect it.
