@garyd9 said in Duet 2 Upgrade Prints coming out stretched:
What type of printer? Cartesian? Delta? CoreXY?
jeez. i actually forgot to mention that 
It's a delta. Ill edit my first post to include that info and the config.g file.
Edit: Well the forum doesn't allow that, so here it is:
Printer Information: Delta Printer 300mm diameter 0.9° Steppers
