Any update on this? I would also like to avoid having to manually heat the printer at the start of every print. Moreover if you’re working with different materials (e.g. TPU, PVA) it is too easy to make a mistake and heat to an incorrect bed or hotend temperature. For some low-temperature materials this could cause carbonization and jamb the nozzle. The best/simplest solution would be for Canvas to leave a copy of the non-blocking preheat commands (e.g. M104, M140) before the Palette-specific start code. That way the hotend will automatically start heating when the print starts and nothing else should be affected. I’m going to test that that works and will update this discussion.
