Random Letters Missing During Laser Cut – Only Works Fine One Letter at a Time

Hi everyone, I’m having a strange issue with my laser cutter and I’d love some help figuring it out.

Laser jumps and does not cut the image on the cut line

I am operating macOS Sequoia 15.5 on Apple M1 system. After installing v2.0.00 and trying to cut the laser will jump and cut a line that does not exist on the workspace?

Any suggestions would be appreciated, [IMG_8505]
