Custom command not queued

Hey everybody!

I create 2 custom commands (M10 & M11) to control a door locking system. Everything works well and I can lock and unlock my door using a out pin.

But the command never queued after move commands, it is executed instantly. It is a bit tricky because the door unlock before the moves ended.

Do you know how I could make it done after moves, I mean in the same order commands are send to the board.

I attach my Marlin_main.cpp if its can help!

Thanks!

Put an M400 Gcode before your M10 or M11
The M400 will wait until all prev movements Gcodes ends.

Yes. Use M400 to drain queue. The problem you are seeing is commands get queued. The movement commands take time to execute and Marlin is processing future commands trying to keep the nozzle busy. But your M10 and M11 get executed immediately when they get processed. And that means there are still movement commands that have not finished being processed.

Hey!

Thank you guys! I did it and it works well!

I did even more thanks to you advice, I implented directly the M400 called fonction in my custom GCODE M11 : stepper.synchronize();

Bye!
