Description

Steps to reproduce

Go to clip overview. Right click an empty slot. Drag n drop the “point creator” into the canvas. Save and exit the editor. Arm laser. Turn on the clip with the single beam. It will turn on for a second, then cut off and turn off the laser. It should stay on as a single beam. Then if you play a clip on a different layer, and turn on the single beam clip, it will stay on.

Hi Niels!

Could this be the scan fail safety (SFS) system on your laser? What is your laser?

All the best

I was gunna say, that’s the exact expected behavior when the laser has scan fail enabled or present - it’s preventing you from burning a hole in your wall

[otto (Niels Otto)]

Huh, never knew about this. Though I have seen lasers burning in walls I know Madmapper Laser has a setting called “enable single beam”, so I wondered if it was to do with software. I’ve tried it with two different lasers. One I don’t know the brand of, and now one from Laser Verkoop 4W laser.
So it’s a hardware limit? Any way to go around this?

[seb (Seb Lee-Delisle)]

I think everyone has been caught out by this at some point so I wouldn’t worry! It’s often a button or switch on the back of your laser marked SFS, but they’re famously quite unreliable.

There’s currently no function like this built into Liberation but I should probably add one
