I took the filament out to clean the nozzle and forgot to put it back in before I started the print again. With the filament out, I could clearly see that the bed was not level. It looks like it’s off by over 2 millimeters front to back. I was testing the Z-offset with a very small test print in the same area so it was only calibrated for that one spot.
Unless anyone has any better suggestions, I’m going to follow the instructions here: Method to prevent nozzle from digging into print bed
I’m on travel next week though so I probably won’t get to it until the week after. I will update then.
Thanks all!
