Ahh, the joys of the Chinese machine controller. Sounds like they have one of the motor windings reversed.

Now I don’t know how best to describe this to you but your Z axis stepper motor has two windings A-A1 and B-B1 it doesn’t matter which (A or B) but you need to swap the connection of say A-A1 to make them A1-A. This will make the motor rotate in the opposite direction for the original command (do not swap an A with a B).

Does that make sense ??

If it's any help I think that the C1G was the preferred replacement - it is basically the same BoB but allows individual pull-up / pull-down on the inputs so they can each be set as required.

Although the UK patents office discontinued accepting patents for this a few years back it has not stopped the continual publication of claims of perpetual motion success. There must be many people out there that are gullible enough to spend the rest of their lives and money on an impossible machine.

Config. / Ports & Pins / Motor Outputs  -   change Direction Low Active state for your X axis.

Well Gentlemen, I have been following with great interest and I think you may have given this it’s best shot. This self-same issue with the C10 BoB has, to my knowledge, come up twice in the past and neither time was it resolved in a satisfactory manner.

I really thought that the passive 120R would do the trick but it looks like an active solution – perhaps a simple inverter or opto-isolator may be required if the C10 is to be used (short of attacking the circuit board and removing the damn pull-down).

Overall, I think replacing the C10 with something better may be the way forward.

Excellent catch Fixittt I think the missing port 1 entries have been the problem.

Thanks if I have anymore questions I will get back to you you are the only one that I get a straight answer from.

That's probably because I don't know as much as the others.

Yes, it should be no problem (I do that without issue) but if you are using a VFD then do not run the spindle supply feed in the same track.
