Gmoccapy - spindle restarts at program stop

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.

Hmm the spindle seems to stop on my machine...

 

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.

faced the same problem yesterday, program about 9,000 lines, LCNC 2.9.2.47

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

Update from 2.8 ISO from repo
