I would like to use the post processing in Cura for change filament on my SV03 and SV01. Every time I set it up, the printer doesn’t pause but keeps printing. On both printers I have touch screen but on my SV03 I have BLTouch. Does the Marlin firmware need an upgrade so the machines can recognize the post processing of change filament command? What do I need to do to be able to do this feature in Cura?
