Project time change

I’ve been using LB for a while now, and recently ran into an issue I can’t figure out. Projects I’ve done before that have only taken 2-3 hours per lightburn now have a 9+ hour time stamp. I cant figure out what’s going on. Omtech K40+ machine, windows os

If willing, share a bit more to help with may have changed from the last time you ran this file.

Post the LightBurn project file.
Did you update the firmware of the laser controller?
Do you remember making adjustment to the ‘Optimization Settings’ found in the ‘Laser’ window?

Not that I’m aware, but I’ll post the file. I have the lightburn ready Omtech
