RE: 6.4.0-RC Firmware for Prusa CORE One

This is the freshly dried orange pla first layer. after first layer it looks like it should. did they change something with automatic first layer in this firmware?

Just launched a quick 30min dual color print with 60 toolchanges. Nothing special to notice, the first layer is good as usual. I need to try with a larger surface to confirm.

Thanks for the confirmation. I'll definitely try that spool on the core one or mk4 just to see. it may be nothing to do with firmware. the two post upgrade prints I did on those two printers yesterday had no first layer issues.
