With help and advice on this forum and the Mach4 forum I finally have my VFD and spindle working. the 107 calibration worked perfectly and Mach4 turns it on and off in the proper direction. What's left is a bit of a head scratcher. The speed controls in Mach4 are inversed. While the spindle is running moving the speed control slider up for higher speed slows it down and it speeds up if the slider is moved down. Has to be a simple setting somewhere but I haven't tracked it down. Can anyone point me in the right direction?
Thanks
