Top left corner cuts too deep

[LiquidSchwartz (Scott Ramsdell)]

Hey everyone can someone help me ID why my Mira 7 is doing this only in the very top left corner of the bed? The words on the left side look too melted… but the words to the right are fine. Same exact settings, 115 speed and 15 power. If I adjust the power down it’s too weak everywhere else… oh and in that same top corner 100% power doesn’t cut all the way through. Thanks!

Edit: I cleaned mirror 2 and 3 and it’s much better!

Given both conditions and the picture, I think you have a mirror alignment problem. The beam may just be grazing the nozzle when in that corner. Make sure your 3rd mirror alignment is spot on in all 4 corners.
