Hi folks. I'm working with a MakerFarm Prusa iV3. I want to calibrate my extruder but everything I've read seems to need the printer connected to a computer. I don't have one connected. Is there a way to do this without a PC? I see under one of the menus there is Move Axis, and it does have extruder, but I don't know if that is how I would do it.
Any help?

Thanks in advance.
