I have an Anycubic Chiron printer and use Ultimaker Cura for slicing. Recently I printed a simple clip, had no problems whatsoever.
I have since upgraded Cura to the latest version, and now the PLA will not stick to the build plate. The printer will make 3 passes whilst printing the brim, then it all collects into a ball. I have checked the level, all is OK, I have increased the temperatures, with the EO now at 225 °C (was 200 °C) and the bed at 75 °C (was 60 °C)
Does anyone know how much or what was changed by Ultimaker in the latest upgrade?
