Mesa 7i76 spindle issue

Hi,
When I start linuxcnc I can start my spindle with button or with MDI M3 S20000. All seem to be OK. But when I start a code, spindle start and cut immediately at next line.
If I add G4 P10 just after M3 S20000, spindle rotate during 10s and then stop when line G0 X0 Y0 is read.

My configuration has been describe in this topic:
forum.linuxcnc.org/27-driver-boards/3841...ection-issues#228910

Someone can help me?


 

I attached my code.
But you will see, there are nothing very exotic.

It seems that I have something wrong with my card because when the spindle stop due to next line, I have to restart (turn off, turn on) my controller, if not button for start spindle manaully doesn't work.
 

Problem doesn't come from hardware because restarting controller is in fact not necessary. Only linuxcnc have to be restarted.
After restarting it is possible to launch spindle but when I start code without M3 S20000 and I stop, after that, command of spindle is desabled (button and MDI M3 S).
 

What are the states of spindle on and spindle speed out
when the spindle stops?

I checked :
- halui.spindle.0.is-on: commute correctly from true and false when I press button
- spindle-enable: true false OK
- spindle-at-speed: true OK

Grounding spindle isn't impossible regarding instruction from supplier.
VFD is normally grounded via mesa card??
 

Interference sound good because mesa and VFD are in the same box. Probably something to improve.
 

After some test, issue appear when I try to launch spindle manually (with button). If I launch gcode without spindle, I stop and then I launch again with spindle, that works.
Probably something between interference and/or manual command.


Another thing is that I use LinuxCNC installed onto Mint19.3 with:
=11.5ptlinux-image-4.9.0-13-rt-amd64_4.9.228-1_amd64.deb
buster 2.8-rtpreempt
my version is 2.8.2-89
This is not version from debian.
