I've just done a CNC conversion to my Chester 16V mill. I'm using an Arduino Uno with GRBL as a controller, and I'm really happy with how its all working. (photo attached)
My next step will be to replace the stock acme leadscrews and brass nuts with ballscrews. I'm looking at using SFU1204 ballscrews on the X & Y axes, but on examining the current setup, I can't see how I can find the space under the table to fit ball nuts where the current brass nuts are mounted.
I'm guessing I can't be the first person wanting to do this, so hopefully somebody can give me some advice on how to go about fitting ballscrews to this mill.
