Rob,
Lie, is your system using stepper drivers or 'real' servo drives with
encoders?
For stepper drives I could draw up the schematics for this (using standard
logic circuits) quite easily.
I using 4 pcs of Pico univpwm servo drives with Panasonic 200W, incremental
encoder

Hello,
I just nearly completed the project of retrofitting of CNC router, with
tandem configuration on the Y-axes
(i.e. 2 motors on the Y movemet).
Can I get help from members who had done the setting of homing sequence in
HAL for this tandem YY?
The controller used is univpwm system from

Excellent point, and no, there do not appear to be any joints
between the two sides. (Dr. Lie has sent me photos of the
machine.) That is going to

like 80-20 extrusion plus several round ways between the two ends.
