When I first installed Mach3 I could set the jog increment to
1.0000 ,0.1000 ,0.0100 or 0.0010 and set it for single step then
pressing the jog button it would jog as I would expect it to
setting it to 0.0001 didnt work so obvious. For about every 8 presses
on the jog button it would increase by 0.0005 but I doubt I would want to
jog in steps that small anyway
So far so good .
My lead screws are 3mm pitch and my motor drivers are set to 16 microsteps
and the motor is 200 steps /rev so I calculate that as needing 1066.666667 steps per mm
When I went to motor tuning I changed the original
Steps 2000 , velocity 120 acceleration 4 to my calculated
Steps 1066.7 velocity 120 acceleration 4
The motor moved as expected . Doing G0 X3
made the motor rotate one full turn which with a 3mm pitch screw gives me 3mm.
Now I went to jog ,
setting step size to 1.0000 and pressing jog it read 0.993 , then 1.9996 , 2.9999 ,4.0002
setting step size to 0.1000 and pressing jog it read 0.0994 ,0.1997, 0.3000
as the step size reduces the problem gets worse
How can I set it to suit my motors required step rate but still work correctly in jog mode ?
Also in Config/General config is a table that will select step size each time you press Alt J
it has 10 lines , but as I dont want to jog in 0.0001 steps I really only need 8 lines.
Is there a way to achieve this without just duplicating a line to fill up the space

Don
