    I recently decided to abort the TinyG and install a PMDX controller, steppers and Mach4, which works well. Someday, someone will change the code. I am not a programmer and it doesn’t matter to me any more. The TinyG can collect dust.

    I’m running the 440.20 version. What I’m asking is a change to the TinyG firmware to have a switch for the 4th axis to be either linear or rotational.

    Yeah, been there, done that. It doesn’t work. The Tiny G actually locks up as soon as any “A” axis command is executed. Is changing the firmware a big deal?

    The machine has two parallel axis horizontally and two parallel axis vertically. They all need to work independently of each other. This one is a partial of a foam airplane wing. See sample Gcode created by Foam Works software:

    I have the same problem. Although I’m tring to use the A axis as linear only and set it to Radius mode. As it turns out, it doesn’t matter what mode I’m in, tring to move the axis will lock everything. It does move every now and again, but nothing that can be predicted.
