I need the Change Filament Screen to allow me to go to a lower temperature if I desire. I want to do a cold pull of PETG at 130 degrees (It’s not really cold, but that’s what they call it, anyway) If I use a different filament I want to be able to do a cold pull of that to help remove as much material from the extruder nozzle as possible before loading new material in there.
On my other 3d printer, I had a bunch of PLA crystalized in the print head because I couldn’t do a cold pull (their extruder gears don’t have an engagement spring that I can push against to clear the gears out of the way)… and that crystalized PLA was a HUGE pain in the butt to get rid of. I finally just had to burn it to the point that it broke down and push it through.
The Snapmaker’s design allows the filament to be pulled out at a luke warm temperature so that the filament releases from the nozzle walls but still comes out as one piece.
I also would like to repeat the request for bed calibration to be done with a heated bed setting. Let me specify an 80 degree temperature for my bed calibrations. Display what ever warnings you feel like you must display, but the bed calibration changes in a big way between hot and cold. I can command the bed temperature manually with a USB cable and a computer, but that is cumbersome. Let me specify bed temperature during bed calibration and show me the current / commanded temperature when using that option during calibration.
