M03 will not turn spindle on
« on: December 15, 2018, 08:00:09 PM »
Hi all,
I have little MIB2030 CNC router with 500W DC spindle that is PWM controlled. I managed to set everything up except one issue I have - the G-code will not turn the spindle on. Yet I can turn the spindle and control the RPM with the spindle button in MACH3. When I type S12000 in the MDI screen, I see that the speed gets setup properly in the SPINDLE SPEED WINDOW.  Then I type M03 and nothing happens.
I also tried "M03 S12000" on a single line and still no success. Yes as I mentioned, if I press the spindle button in the MACH3, the spindle starts every time.
what am I missing?
Thank you for your help...
