Ok so I am nearing the end of my first Mendel build (TechZone lasercut, TZ gen 3 electronics, pinchwheel extruder). After I hook up the extruder and get that working tonight (hopefully) I will verify that the Frame and everything else is square, level, correct spacing, etc. I have already wired up the motors and controllers, I am able to jog the axis's as will in both directions. What I would like to know from you guys is what are the steps to get the machine ready to print. Such as establishing a 0 point for all three axis, since I will have min_stop opto's. Do I manually jog the machine to the ends that I want to start as a 0 position and then restart the software so that will be the default spot to start with? I saw in another thread somewhere (can't find it again) that each axis has a higher and lower position in regards to right and left?
