Hello,

is this Spindle Stop/Restart bug fixed in newest release (v2.9.2)?


No. And I can't reproduce this with a simulation config. I appreciate input on this.

  I am trying now in v2.9.1, gmoccapy sim.
If i open arcspiral.ngc, or 3dchips.ngc from nc_files, i can't reproduce the problem, but if i open my gcode file (%fej.ngc - attached) the spindle is restarts after i press the program stop gui button.
I will try to find which g code in the file causes this behavior.  
Please try to run and stop the attached file.

I think the problem was in the length of the file.
My original gcode file (fej.ngc) has about 12k lines.
I deleted 1k lines from the end of the file (M30 remains on the end of file) while the bug remains.
The Spindle restart bug disappeared if I deleted ~10k lines from the program.
When the file has 3k lines, the spindle restarts after the program stop button is pressed, a file with 2k lines not - works how it needs to.

I think with this method you can reproduce the bug.

Hm, interesting. I will check it.
The difference is that I compiled the linuxcnc from source. Dont use preinstalled version comes with ISO, only reason is to compile from source is to increase #define HAL_SIZE (75*4096) in: linuxcnc/src/hal/hal_priv.h, becouse I use many components in HAL.

Hello, you use LinuxCNC installed in ISO, or downloaded the source, and compiled it?
