I have a DIY CNC 4 axis router controlled by Mach3 & parallel. My spindle is a Bosh 1617 controlled with a SuperPID. Mach3 outputs a PWM signal to the SuperPID and works great. I decided to dump the parallel port control and install Dynomotion's Kflop and Konnect boards. I am driving my stepper amps directly from the Kflop and the limit switches with the Kconnect board. The Kflop board has been just a bit tricky to figure out but I am getting there. My question is, has anyone used a Kflop board to drive a SuperPID using PWM rather then 0 to 10 volts outputted with a DAC? ANy help would be appreciated
