I'm looking for some pointers as to where to start!
I have a Syil X4+ that is used from time to time and recently I have found it very frustrating. When running a job, the spindle will stop mid job and then immediately start up again and repeats it until I press the e-stop. Now, the last job was:
1.3mm rectangular cut (with radii) in ally and a very slow feed using an 8mm cutter.
I can get the spindle to slow down using my hands but I can't stop it. However, a 3mm slot drill will stop it - and break the cutter! So I suspect it is software related rather than the motor.
Any thoughts as to where I should start looking?

Hi,
you need to use a multimeter to measure the PWM 0-10V that controls the spindle. If it fluctuating then Mach/UC100 is at fault, if its steady
then the spindle or VFD is at fault. May also need to look at the On/Off relay.

Thanks Craig. It is a starting point for me and will feed back in a week or so when back from hols. I will also reload Mach3 as a chum suggested that may even help (it did for him when he had a strange issue).

It looks very much like a protection trip. We need to look for the cause: maybe one of the limit sensors is triggered

I'm in the process of bypassing the controller for the spindle motor and using the speed operation independently. If that overcomes the issues, then it will be a full upgrade with UCCNC & AXBB-E
