I'm actually having numerous issues but I'll try to narrow it down.
Using a mac to connect to a pulse xe e-223s
Went through the whole calibrate and leveling. Wasn't getting good quality and also had mattercontrol crash a few times (maybe just tried printing too big at first go). Switched over to sdcard, not much improvement.
Since I am printing with PETG, thought maybe the nozzle was to low (along with tweaking temps). Went through calibrate again but made sure paper was more loose. (I've since found the z-offset in MC but never used it)
I exported to an sdcard and for some reason it decided to go lower than what was just calibrated. Scratched up the garolite. Luckily I caught it fast. But shouldnt it auto-magically add all the information when exporting?
So I switched garolite (glad I bought a spare). Deleted the printer and wanted to start from scratch again. Went through the whole calibration, and used the temp settings I learned to try again, printing directly to it. It was pretty good. Needs a few more tweaks. Shutdown the printer and put my laptop to sleep. Today I was going to print again and now the nozzle is trying to print maybe like 1cm off the bed.
I am scared to re-calibrate because I don't was to ruin another garolite and I shouldn't have to.
I also have a PEI sheet that I tried out at the beginning and of course I re-calibrated then too, which makes sense when switching beds.
