- Jul 2, 2012Hi,
About 10 years ago, I converted my RF31 to cnc (servo drives) and
ball screws on the X and Y axis. I was given a prototype breakout
board that I use till this day on it. Spring loaded double nuts were
used for zero backlash. For the Z axis, I put a servo on the fine
downfeed and tweaked the gearing arrangement to reduce the problem of
backlash. For a power supply for the gecko drives, I rewound a
microwave transformer to get the desired voltage and made a simple
power supply with a Bridge Rectifier and big capacitor. My control
software of choice was and is Turbocnc.
I don't know of any "kits" for this model of machine and when I did
mine, I pulled the table and saddle off to make measurements. Matter
of fact, I did that several times to get it right and to make the
mounts etc that I needed. You can see some of how I did it on my old
web page at:
I will be glad to help you if I can.
