Reduced power during burn

Hi, I’ve been using LB for a few months now and with no trouble until the past few days. My programs would stop mid burn for no explainable reason. Today after firing up I couldn’t get the machine to lay a burn at all using the LB software. Checked it in lasergrbl and was able to do a simple power test, brought same file into LB and let it run the whole test and it didn’t make a mark. The laser is firing, focused and set at 35mm. Everything moves correct in x and y, just no burn unless I do multiple passes so it seems like a setting somewhere is limiting or reducing my power but I do not know where or why.

Edit: I am operating an Ortur LM2 20w, newest firmware released last week, newest version of LB released last week, and Windows 10 on a lenovo laptop.
