Ok, I got a weird, hopefully fixable, problem with my Photon.
it's about 10 months old, and I've printed hundreds of things without issue. Normally I do not relevel between prints, I just remove the plate, remove the print, put the plate back. No problems.
Last thing I printed had a lot of surface area and was large, so it took some doing to get it off the plate. I knew for sure the plate had shifted. OK, will relevel, no big.
My ideal z0 is right around 12mm below the home, so I usually home it, down 10, down 2, try to wiggle the plate, feels tight, tighten the screw and re-z0. Done it many times before no problem.
Now, however something is pretty screwy. When I try to relevel now, I get exactly 2 options:
Option A: Too high. I have my vat removed and am using an old FEP between the plate and glass. I get it tight, no wiggle. I tighten and re-z0. I do a test print as is (no vat in place, just that spare fep. The plate homes, and then starts "printing" at least 10 mm off the glass. This is not where I z0'd it.
Option B: Too low. Same technique as above. This time, the plate moves to the glass, and makes a hideous grinding noise for about 3 seconds. Prints actually come out OK this way but I assume something is going to wear out. This is again not actually where I z0'd it.
Those are the only 2 levels I can achieve now no matter how much I play with the stepping (maybe 11 down instead of 12, playing with the smallest increments, etc).
Occasionally when a print finishes now, it also overtravels up - instead of moving above the vat about halfway up the track and stopping, it moves all the way up the track, keeps going, is stopped by the blue thing on top, and again makes a hideous screeching for about 5 seconds before moving down a bit and pronouncing the print finished.
How do I fix this? Can I fix it?
(follow-up edit: running the config file and re-zeroing totally did fix this).
