Sieg X2 convertion advice

[Jonathan]

The cheapest (and therefore probably the worst) way to convert it would be to simply put a pulley on each axis and use that to connect stepper motors via timing belts, without changing the original leadscrews. There will be a lot of backlash and the maximum feedrate will be fairly slow, however it would still be use-able and enable you to CNC mill the parts for a better conversion using ballscrews. I put stepper motors on my mill this way, but never got round to changing to ballscrews since the router does most things the mill can do:

I would really like to do it with ball screws but if costs rocket then some sort of anti-backlash for my current setup would be great.

My mill has quite ALOT of bacl lash i would say at least a full turn of the handle so its quite dire!
