Ok i am doing a CNC conversion and also a motor swap/vfd install on my grizzly lathe. trying to test out the new motor with mach3. i have it hooked up to the VFD and it runs fine. i then wired up the vfd analog output from mach to the analog input on the vfd. i load mach3 with the gecko xml. switched the frequency control of the vfd to external input, not sure where to go from there to get it working.
