Hi everyone. I just ordered a C-Beam XL bundle with the stepper motors to replace my old, warped and much modified Probotix V90 Fireball. After three moves around the world and several controller updates it is finished. The moisture in my garage here has also done a number on the MDF. Unfortunately the CNC xPRO controller is out of stock so I am contemplating keeping my Planet CNC USB Mk2/4 card especially as I really like the CNC USB software that I purchased to run it. The problem I have is that I only have the three ProbostepVX stepper drivers for it from the original V90. If someone has one or two ProbostepVX drivers laying around they would like to get rid of, problem solved! If not, can someone recommend a suitable controller/driver for 4-axis and a rotary? I would like to maintain the CNC USB software or find a free alternative that provides WYSIWYG interface. Thanks and I look forward to posting on my progress once the kit arrives and I know I'll be reaching out for help when I begin milling.
