Hello,
I tried the last days to understand why jogging incremental with onscreen buttons vs extern buttons does not have the same step size.

When I change the step size over the GUI button then external button and onscreen make the same step size.
=> Everything like it should be

When I change via an additional external button the step size then jogging with external button makes the right step size
but onscreen buttons make the last onscreen set step size regardless that the onscreen display of step increment on the GUI is changed by the external button.

Simplified said why is "2022-03-22 20:37:25.551 - API: mcJogIncStart(inst = 0, axis = 2, inc = 1.0000) (Mach4GUI Button)" not changed by the external button step increment change?

Can somebody tell me what I miss here?
Some Logging and Code below.

Thanks

Gerhard

You need to create a custom jog function that reads the set increment with mcJogGetInc and performs the jogging. The built in Jog actions won’t read the value set by mcJogSetInc. These API calls set registers which you can see in the register diagnostics and I believe are more of a placeholder for custom jog stuff.
