Twist that Pineapple coupler while it’s printing (if your using the MPCNC)! Usually a click or two is all you need. If you are having a hard time getting it right make a few more skirt loops to give yourself more time. After some practice you’ll be able to get it right every time. For a machine with no end stops your should be starting with the nozzle touching the surface. There are a bunch of guides out there saying a business card or piece of paper should fit under the nozzle, not for us, touching is what you want. When the print starts it should first pick up the correct first layer height then move.
