3DPrinting

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.

Check your thermistor and do PID tuning if you havent already. Your temps are high, but exact number doesnt matter if it works for you. You can see how stable is temperature curve while doing PID. Maybe print temp tower and post picture here

I ran a couple temp towers with the overture petg and I found 270-275c nozzle/80c bed had the most desirable results. 0.6 nozzle 0.15 layer height. also with the sprite pro.

I printed a couple pretty pieces before I started to get burnt crusty bits showing up in my prints so take this with a grain of salt. maybe due to me changing layer height to 0.14 without further testing.

This isn't far off from where I print PETG with a stainless nozzle for 125mm/s. If you're using a brass nozzle and not pushing speeds then it seems high.

Have you PID tuned it?
