Laser not firing issues after upgrading 0.9.11

[patrickday (Day)]

I literally just got my first machine (80w chinese with Ruida 644xg). two Issues i’ve noticed since upgrading to the newest version the other day:

1. 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.
2. VERY ODD. Laser will NOT turn on for cut/line if the speed is 10mm/sec or lower. It will work for Fill. But FILL + LINE, only the Line works (it goes through the pattern, laser just doesn’t fire). Changing of power does not have effect, only changing speed to 10mm/sec or lower. I think it’s working right when over 10mm, but i need to keep testing.

I know everything was operational prior to installing the update because i was trying

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

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.

Rick: THAAAANK YOU! I thought i was going crazy. I would have never found nor understood that minimum setting. You Rock.
