General Mach Discussion / Changing Spindle Speed

« on: July 10, 2018, 02:31:23 PM »

I am trying to change my spindle speed very often in my gcode (every second line) and that results in random feed accelerations and decelerations.
It seems as though the gcode execution almost stops at times.
When I look at the current line I often notice that it jumps to previous lines and then forward again.
What is going on?

Here is a code snippet :

( w gti)
#1001 = 178.29 (diametri i jashtëm)
#1002 = 65.4366 (diametri i mbrendshëm)
#1003 =  23.324 (x ZRef)
#1003 = -5.86 (z ZRef)
#1004 = 0.2 (rrezja e thikës)
#1005 =  0.1 (thellësia e prerjes)
