Ah, yeah crashes are all on VSH maps so that explains it. Thanks!

If you’re happy with your prints, then no need to calibrate IMO. I think calibration is only necessary when you see a problem or want the best possible prints you can get. But personally, I don’t care too much if a print isn’t perfect, as long as it works

New brand seems reasonable. I still don’t even do that, but I also don’t care too much if it’s not a perfect print haha
