Feature Request: 4th axis assigned to any other with invert #122

Closed Sunnysky closed 6 years ago

Sunnysky commented 6 years ago

Is it possible to add a feature for dual Y motor XY Gantry with dual drivers to have a 4th axis?

Grbl Controller 3.6.1 has this where you can assign to the 4th axis to any 3rd axis then invert any of the 4 axes.

I have grbl 1.3f with Genuine UNO and a 4 port CNC Shield.

If not then I have to hardwire two motors in tandem with polarity reversed so CW=CCW then boost my current limit and add a fan for cooling.

I just love the user GUI interface. It is VERY well thought out for usability, features and appearance , and all the # parameters in a nice viewable tab. I have looked at 6 programs so far and I love this the best.

I see hardware jumpers for cloning are easy on CNC Shield and 4 pin motor cable rotation, reverses polarity easily over a header.
