I am getting a message in the history box that states "Spindle speed 1 RPM bumped to min PWM duty cycle (5%, 5 RPM). Is this a limitation of the board (PMDX 410 with a PMDX 132 using port 16), smartBOB, or Mach 4?
I am using the spindle to control the laser. I drop the power way down to position the laser to the home on the work piece. 5% can still burn the work piece if I don't move pretty quickly. It would be nice to be able to have a lower power level (perhaps 3rpm)
