<p>I have an Anycubic Chiron printer and use Ultimaker Cura for slicing.  Recently I printed a simple clip, had no problems whatsoever.</p>
<p>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)</p>
<p>Does anyone know how much or what was changed by Ultimaker in the latest upgrade?</p>

The printer is 3 months old, bed is cleaned after each print.</p>\n<p>I then tried the new Cura version again but with glue for adhesion,  that works.  It seems that it is changing the bed temperature, and using a lower default.  Have tried changing the bed temperature in the software before slicing, but found I have to manually set the temperature on the printer, I have been using the generic settings for the PLA, as the ones I have (E-DA) are not in the selection or in the market place.  TPU and PETG are printing fine.</p>\n<p>Will have to determine the optimum set-up and create my own defaults.</p>\n'}]
