Small gaps where laser starts and stops each letter, any suggestions

[Rick (Technical Evangelist)]

This is one of the most common issues folks report for the Ruida controller. There is a threashold for firing the laser and that is controlled by the speed and power settings for that job.

Read here for a deeper understanding of this behavior.

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.
