real 4 axis values and AXIS prog. is not the same was created by leintz
hi !
I have a problem with 4 th axis unit values..

But the AXIS show me different values....
command G0 A180 turns the 4th axis only 146.5 degrees....but AXIS show me 180 deg ???
no lost steps....

Check scale figure
Do tests with different commands and if the movement is consistantly short eg G0 A90 moves 73.25mm then that is your problem.
If this is the case, your scale figure is 65.925% of the figure required
(just beware that in some circs with a rotary axis, linuxcnc will be 'clever' and take the shortest route if you command a position rather than an incremental move)
