Retrofitting a series 1. I want to keep the original steppers. Planning to use:
Keling 6020 power supply
Gecko 203V's
Laptop
Smooth Stepper
Mach3
GE VAT20 VFD (for 3 phase to motor)
Looks like there's a wide range of breakout boards that will work with the smoothstepper from CNC4PC's C25 ($30) to PMDX's 126 ($170). Is there really any advantage to spending money on the more expensive breakout boards?
By the way, the only other machine I've built used a G540. This will be my first attempt at using a separate BOB so I won't pretend that I understand everything about them just yet.
