Problem: Spindle stop for tool change, while still in motion, before operation completes. #1375

This is hard to reproduce on my test fixtures. There should probably be a Probably right before if (gc_state.selected_tool != gc_state.tool) {
bool stopped_spindle;
Spindles::Spindle::switchSpindle(gc_state.selected_tool, Spindles::SpindleFactory::objects(), spindle, stopped_spindle);
if (stopped_spindle) {
spindle->stop(); // stop the new spindle
gc_state.spindle_speed = 0.0;
gc_block.modal.spindle = SpindleState::Disable;
}
spindle->tool_change(gc_state.selected_tool, false, false);

Hi.. thanks for your reply.
I went into the source code and saw this function call as well. But not
pursuing where this function originates from because I think I'd spend the
time to test on another gcode file.
Found out everything went well for another file (and combined operations),
and did the same thing again on the same 'problem' file, even after I
rebooted the machine and restart UGS on my laptop.
I understand this is hard to replicate on your setup but can you at least
share with me what kind of situation that might contribute to this erratic
problems..? Let me know if you need more info on my setup or whatever it is
to narrow this down.

There should probably be a protocol_buffer_sync(...) here to complete all
buffered gcode.
Probably right before spindle->stop();
if (gc_state.selected_tool != gc_state.tool) {
bool stopped_spindle;
Spindles::Spindle::switchSpindle(gc_state.selected_tool, Spindles::SpindleFactory::objects(), spindle, stopped_spindle);

We are discussing it here. There are some fixes on a PR. I still need to test multiple spindle systems and macro users. https://discord.com/channels/780079161460916227/1304881649439473748 |

I need some help with this. |
|
I'll create a pre release with the new code. Is that the help you need? |
|
Yes, please! I very much appreciate your help on that mstter. Thank you!

Pre-release is done. https://github.com/bdring/FluidNC/releases/tag/v3.9.2-pre1 Get it via Github or the Web Installer (be sure to enable pre-releases) |

Awesome, thank you so much! I had to shutdown my machine yesterday after I
can't progress with my work, no matter how I changed the milling operations
or restarted the machine.
I'll make the update today and report the outcome accordingly.
Thanks again.

Happy to report that the 'early stop' spindle bug is gone. There's something else that i thought was part of the erratic problem from the current 3.9.1 release, but persist in the 3.9.2 pre-release. I'll keep an eye for the current state of update and notify if there any other problem. I'll open another issue later base on my findings. Perhaps another video too to document the tool change procedure. Thanks for this! I'll make a donation soon as a token of gratitude for all your work guys.. |

What happened?
The spindle stopped before the operation completes. I've uploaded a video to youtube.
The part has a round and oblong shape to pocket. In the youtube video link, I initially combined the 2 object into 1 pocket operation. So there are 2 tool change in the video. Last operation is chamfering.
In the gcode & output attached, I separated the 2 objects to run into separate pocket operations, having in total 3 tool changes. Last operation is chamfering. I did this to see if the spindle stopped in each intermediate tool change, but it only happens while in the oblong shape pocket operation. It did not happen in the round pocket operation.
The video can be seen here
