Pass Through Stopped aligning correct

Was working fine. Trying to cut 1/8" acrylic on a couple pass through cuts and it won’t align correctly after each pull thru. (not automatically or manually) I’ve throughly cleaned lens, machine, air assist and exhaust fan. Help! I’ve wasted so much acrylic

when you say it did not align correctly, you mean that from the app screen it looked off? As opposed to the designs looking correct in the app but not cutting correct.
