I guess if you want to, it doesn’t hurt anything, it just takes time. I like that I level the bed once and it stays level. ¯\_(ツ)_/¯
Obviously, we come to different conclusions here. I’m trying to understand. Why level between prints? If it’s changing between prints without disabling stepper motors, something is very wrong with the printer (like binding) which will also show up in bad print quality, right?
My original bed-flinger had two Z axis motors on a single stepper, and it mostly stayed in sync. But when it got slightly out of sync, I initially didn’t understand what had happened and would adjust the bed instead of one lead screw. (That printer has since had its parts repurposed…)
Which models have enough degrees of freedom in each bed mount to enable non-planar printing? Using a maxwell kinematic coupling with really long grooves maybe? Have I missed one of this printers actually being reasonably configurable for non-planar printing?
For most printers, I doubt the degree or two you can get before bending things from racking forces will enable meaningful non-planar printing, and having multiple motors just gives plenty of failure modes in which the couplings can be driven out of sync such that mount elements or drive elements (e.g. the lead screw) are bent. I mean, it has to be explicitly designed for non-planar printing, which I would expect instead to do with a five-axis printer like XYZdims (René K. Mueller) has been playing with than with independent control of three Z steppers.
