Just wanted to come back and say thank you to everybody, I've been terribly busy but that was it! It was a combination of ironing on every layer and the combing. I've turned off the ironing and combing and have MUCH MUCH better results!

I'm banging my head against the printer trying to figure this out. Almost perfect cube with some small but fatal flaws. It seems like it's overextruding at the bottom of the X and Y, and then again on the top surface corner. Please advise!!!

Using Overture PETG filament 1.75
Currently using a Duet 2 Wifi board in an MGN cube running RepRap 3.3 with the Duet WiFi Server Version 1.26 through the latest Cura build. Build is a CoreXY
