HI on that Backlash Q: is it a Ballscrew with that amount 0,12
YOU need DOUBLE the Value of STEPGEN_MAXACCEL = to the MAXACCEL =

With your setup you can do all LIMIT an Home to one PIN and take 2 more inputs free for Spindle encoder and Toolprobe

yeah, bearing blocks are cause of the backlash, trying to fix it with different bearing setup

its all work in progress

thanks

So, first chips yesterday fairly ok but after hour or so of 3000 rpm machining, spindle bearings went bust. Time to change them, AC bearings on order.

In meantime friend promised to bring VFD and question is now following. Can i control Spindle via this BOB or its time to upgrade to MESA ?

Thanks
