I purchased a Denford Novamill, and initially it worked fine.
  Somehow the setting were changed (probily by me), and now when I try to use the spindle speed override, the spindle starts spinning at full speed. This happens when I reduce speed or increase speed.
  I know it's something to do with the Mach3 settings, but I'm not an expert with computers, and don't want to upset anything else.
  The machine has Gecko drivers, and the communication between the Pc and Mill is through an ethernet cable instead of Serial.
  If someone could point me in the right direction (what menus to look in ect.) I'd be very grateful.
  Thanks in advance.

Hello Garry,

Are you using the pn7762 DSPMC motion controller in your mill?

I'm not well up on what's inside, but I believe it may use a smooth stepper, if that makes sense.

The drive is a Gecko 540.

Hello Gary,

Unfortunately, this forum page is dedicated for those machines that use the DSPMC motion controller.

I would recommend posting this issue on the SmoothStepper forum page, or contact the original vendor of your machine for technical support.

Good luck

Thanks. I'll do that.
