Is there a way you can confirm your bed or nozzle temps? I know for the nozzle that's a really difficult thing to do, it's so small to be able to check with anything.
I ask because with your unexpected crash the other day from your post history, I wonder if your main board has glitched.
A 90c bed shouldn't melt petg I'd think, so something is definitely weird there.
Might be worth trying to reflash your firmware in case the glitch isn't hardware.
What other mods have you done to your printer besides spring spacers?
When you level the bed, is it manually and with a piece of paper to help gauge the distance?
These things have so many places something can go off that it's really difficult to help troubleshoot without being there. Hopefully something in this post helps you out.
For the crash my hotend just untightened lowering it lower than the bltouch. I use klipper now so the mainboard firmware akaik isn't responsible for a lot. I have done A LOT of mods which I will list in a reply. For manually level the bed, I just probe 5p times my bed with abl, look at the graph and adjust the knobs in consequence...
Yeah I know it's hard to troubleshoot without being there,trust me,trust me...
Thanks for your help I guess my filament is better at 280C ¯_( ツ )_/¯
Ok, yeah, forget the paper as far as regular leveling goes with the cr touch. Have you tried confirming your z offset since you changed the nozzle? If you haven't, it should be fine every time you do something to the hotend.
Also make sure your heat block isn't stripped out. I had a bitch of a time printing for a while only to discover I had overtightened my middle and stripped out the threads in the heat block. After I replaced it I had consistent good prints again.
Oh don't worry my z offset is set tight! And for the heat block I always undertihhgened and it leaked everywhere so now I tighten it firmly but not too much to the point of stripping the block
