Couplers
From the ever popular CNCZone: Al_The_Man and Crevice Reamer: CR: Only 3 types of couplers offer true zero backlash connection: Solid. (which can cause problems unless PERFECTLY aligned, Helical, or Oldham. Helicals are basically solid couplers with some alignment flexibility. Make Read more…
Dual Closed Loop Control with KFLOP
The Dynomotion KFLOP controller can control 8 motor axis (either as 4 dual/slaved or 8 independent), complete with 8 dedicated hardware encoder channels (while any generic input could be used in theory for encoding, I understand the general I/O speed Read more…

Ball screw Mapping and Compensation
If you’ve done any investigation into ballscrews, you’ll see there’s a bewildering array of variables: metric/imperial, tolerance classes, pitch/lead, rotational moments of inertia, backlash compensation methods. One that may affect cut dimensions is the variation in pitch between one Read more…
