4th axis jogging

[g3grau]

I just started to play with my 4th axis (on a Genmitsu 3030 prover max).
I get the angle value displayed and I can turn the axis with the A+ and A- jogging buttons.
The problem is that I can't really control this movement:

• short pressing one of these buttons starts the motor, but it will not stop! (pressing the same button again has no effect)
• long-pressing one of these buttons runs the motor as long as the button is pressed. Kind of works but only for coarse alignments
• alternating the buttons (short-press) seems to cause a problem, needs the stop button to halt
• I don't see a method to rotate by a certain angle. I guess I could write a macro, but could a macro access the jogging settings (speed/size values)?

Maybe for the angle axis a permanent rotation mode switch makes sense (to simulate a lathe), but separate angle step/speed values and the same behavior as for XYZ would be my favorite.

Tried it with 2.1.13 and 2.1.15 on Linux.

Sounds like your steps/mm setting (or rather steps/degree) for the A-axis is set wrong. If you jog the A-axis 90mm (degrees), does it move a quarter turn?

Or are you perhaps using inches in your gcode? This can become a problem on some controllers where it would multiple the A-axis degrees with 2.54.

Permanent rotation is not possible. The controller synchronizes the rotational movement with the other axis movement.

Hm? After turning everything off and on things look better!
The ABC step is doing what it should when jogging :) and also relative/absolute A axis moves are fine.
Not sure if I made some strange programming mistake?!
So...I assume all is ok, thanks for the reply!
