Laser not firing issues after upgrading 0.9.11

The speed is now locked in mm/sec. I was logging my settings prior to upgrade and all were in in/sec prior and worked accordingly.

You can also flip the Units used with this control: - - - -

VERY ODD. Laser will NOT turn on for cut/line if the speed is 10mm/sec or lower.

Not so odd.

Ruida / LightBurn won't cut below 10mm/s

This isn’t a LightBurn issue, but a Ruida one that’s quite common. There’s a controller setting called “Start Speed” that defaults to 10mm/sec. At that speed, power starts ramping up from Min Power to Max Power. Cutting at or below that speed means you’re using Min Power only, so if you’re cutting slow, set both Min and Max power the same and you’ll have no issues.
