Klipper takes a three hour print down to like 20 minutes. You will want to run your nozzle hotter to compensate, but then you might need a fan to cool the print so it doesn’t run/drip. When you get everything tweaked, it’s amazing. You watch it print at “super speed” and think you are watching a video that has been sped up. Klipper also gives you MUCH more control over your printer than you get on the control module. We run it from Linux on an old laptop, but I’m told it can be on on a Raspberry PI also. I’d like to get my hands on a couple of Raspberry PIs. I need a 3 and a 4 for a couple of projects, but I’m not willing to pay $80 for a version 3 and I can’t even find a 4.
