So my calibration is finally printing a nice 20x20x20 resin saver cube dead center of the machine.
Though the bottom of the cube when on supports is a little ugly.
The real question here is, how far away from center can I go before this accuracy goes away? I did a test print of a bunch of rings - all the same- and I put one dead center and one at all 4 corners as well as one in the center of the left/front/right/back sides.
Center one is perfect. The ones on the extreme edges all ended up squished about 0.4 mm and the supports started to become one with the ring.
So again, if I needed accuracy, how much of the build plate from center should I expect to work within?
