anybody in the group hacking direct drive with screwballs ?
i’ve been playing with 3 42" screws driven by 2amps steppers , experimented with dual screws per axis driven by a single pololu (this failled as the 2 screws where not synch 100%) and i’m back to single screw with 4 linear bearing on 2 7/16" shafts , but still getting some wobble on my X axis , trying to space out my bearings to 4" see if this will solve it , but has anyone gone that road ?
best reg. alls
keep on hacking
