I’ve gotten a lot of problems solved but I have one that is rather persistent. When I print, the first layer or two are wider than the rest of the print. A very small amount, but enough to be noticeable. Gut reaction is “the bed is too hot”. But I run it at 55C for natural PLA and when I tried 50C, I lost adhesion. Also, 55C is also lower than the low end of what’s recommended in the lulzbot filament guide (60-70C).
I’ve tried tweaking the bed temp and the nozzle tem, all to no avail. I’ve also tried lowering the bed temp after printing a few layers. No dice. Any suggestions?
