settings for speed control in CNCNC

[Jimamato]

I have used my smooth stepper, PMDX-126 board and PMDX-107 board for speed control for about three years now. It has worked well with Mach 3 but I have decided to give up on Mach3 and try UCCNC on my router.
My new configuration is as follows. A UC400ETH controller and both my PMDX 126 and 107 cards. I have configured my newly installed UCCNC software and all my functions seem to work except one. I am able to turn the router on successfully but in no way can I control the speed.
Any help I may get would be gratefully appreciated.
Thank you very much.
Jim

You can control the spindle the exact same way in the UCCNC as the Mach3.
I know this is not much help, but we need specific question to help you.
