Hi Milosh,

Keep the settings that's turning spindle on off using single coil. Don't worry about ccw for now. Try unchecking frequency resolution, save and restart UCCNC.

Hi Dan,
Unchecked feequency resolution, but still no luck. Only on off. No speed controll. Just to be clear, when I use the button to turn the spindle on, I shoud be able to overide the spindle speed with plus or minus sign. Unfortunaltely, numbers on the screen are changing but not the spindle rpm.

Thanks,
Milosh

Hi Milosh,

Please try plugin I attached and use settings in pic. If still not working change Frequency address/coil to 0000 and try again. Make sure you restart UCCNC after changes.

Hi Dan,

I loaded ver 16 and tried with different frequency addresses (0000 and 0001) and there are no changes. No rpm control. And I even tried to turn off frequency resolution and checked multiple coils. But no luck again.

Today was a busy day and tomorrow I may try to use different computer.

Still don't understand where the problem is. Is it that we have frequency register address wrong, or is it something else? I think that register address should be 0000h for 0001h register number. Is there something in the UCCNC that may be wrong set (checked spindle setting and PWM is checked, spindle pulley is not checked)?

Thanks,
Milosh
