Hi Mike,
Nope, I only have 3 axis,? ?If GRBL = motion control, then it is easier to go back to Mach 3.
Yes, I have stepper motors and a control box that are functioning that is separate from a laptop.? Unit functions fine.
The control box has a Gecko 540, fan, normal stuff.
Thanks for the suggestion, but I don't want to learn another system, and buy more software.? I just want a pendant!
