3.6.0

Upgraded  from 2.7.0 to 3.6.0. Previous worked like a champ When 3.6 lays down the first lays it doesn't stick and just balls up on the nozzle. I slice it using 2.7 and prints fine. What would I need to change to fix the issue? Thanks

I'd compare your settings between versions, especially initial layer height (0.2 mm)

That was the first thing I did. Everything is set the same.

Compare the gcode output. Export a gcode for a small cube from both versions, and we can start to see what it different between the two.

 

Cura has a LOT of settings. Not all settings are shown but they can still influence your print. It could be that the printer definition you used was changed ("improved") between 2.7 and 3.6. It could be that you forgot to install a plugin in 3.6 (Z Offset plugin?).
