Ah, but what's a decade between friends!

Thanks for spotting that. Nice, businesslike conversion there.

My Bantam looks like a baby version of the M250 in many ways. In my case I mounted the X axis motor at the back of the saddle and fitted linear encoders so I could close the position control in LinuxCNC.

I got my telescopic ballscrew covers from AliExpress but I haven't fitted them yet. Obviously, the minute I do I will need to remove them again and they are the very devil to get off without dismantling the entire front assembly.
