I have a dual y axis drive both motors are running at 3A so I can’t parallel the motors. My gantry is heavy maybe 80 kg.
I want to add a rotational axis.
The way I see it is I can add 2 external drivers(sharing the step and direction outputs from tinyg) which allows me more current and voltage for my y drives and frees up one on board driver for the rotational axis. Hopefully
I won’t need level shifting or buffers to drive the drives.
Only other way I can think of is to get a second tinyg and try to get them working in sync.
I have a v8 tiny g, How do you network 2 together?
The first way seams like a bit of a hack but I think it’ll work best, more power for my y, less heat in tinyg.
Anyone have any ideas / comments?
