I'm using mach 3 with the Campbell Combo breakout board. Mill runs great when I have the jumper on my breakout board set to "no charge pump". If I set the BOB to "charge pump", and under ports and pins I enable "charge pump" to output pin 17, machine will stop moving. I have tried this on both "charge pump 1" and "charge pump2" under ports and pins. I have also toggled between HI/LOW on these. Any ideas? Thanks  |

| Not sure if there is an adjustment for the frequency, but I remember when I set my charge pump up from Mach3 I found the output was 10kHz, whereas the doc said to expect 7.5kHz. Think I got that around the right way. I have the charge pump enabled on Port 1, Pin 17. Output worked fine from Mach3. |
