Marlin has just fixed a bunch of laser timing issues

https://github.com/MarlinFirmware/Marlin/pull/22690, I would say we keep an eye on this for a few days to see if there are any bugs that need to get worked out.

This will show up in our bleeding edge builds tomorrow. Actions · V1EngineeringInc/MarlinBuilder · GitHub I do not think it made it in today as they merged at roughly the same time.

A good break down of the laser use. https://github.com/MarlinFirmware/Marlin/pull/22690#issuecomment-947841760 M106 will still work with M3 being the best stable method, and M4 the new needing more testing method.

I do believe it puts a hard limit on 8 bit boards of 150mm/s, with 100mm/s being more stable.

@vicious1

ESP32 with an I2S expander (tinybee is one) will not work well due to timing issues (Wonder if this is true of GRBL based esp32 boards).

Hasn’t that been addressed with 24193 ?

Oh! looks like it. Thanks for that. Edited the first post.

Also looks like there is a minor bug in the laser merge should be fixed soon.
