Software update fried laser?

[riverwoodsturner (Andrew)]

I have recently upgraded to Lightburn 2.0.01 from 1.7.08. Now my Ortur LM3 with LU3-20A laser is totally screwed up.

1. The cut speeds and power settings for all saved projects are wrong if called up in 2.0.01 but correct in 1.7.08
2. My laser will not fire at all
3. If the project runs far too fast, not what cuts and layers says it should be
   I reinstalled 1.7.08 and the laser still will not fire

Check your speeds are MM/Min not MM/sec, I always recommend after doing an update to reload your preferences file from prior to the update as windows sometimes does not copy the preferences file when the installer tells it to.

Double check S-Value max and ensure it equals your $30 value.. This controls the pwm.
