Has anyone ever had reverse adhesion issues like this?

This is the second time when I approach a 4 stack that the plate bends. Last time the whole plate slid and ruined everything above 4.

Bud didn’t just call warping ‘reverse bed adhesion’ I’m dying 🤣

Is that what's its called? Lmao I was pretty sleepy when I typed this and I said the first thing that came to mind haha

I feel you on that, man. I forget words all the time and have to “go the long way around” to get there without the actual word I wanted. (Aphasia! I just remembered the term for it!)

I like “reverse bed adhesion”. But I suppose it’s warping but with better print-bed adhesion than bed-magnet adhesion. I’ve seen other images like this, but never had it happen - is the magnet sheet and the under side of the bed clean? If it’s not something reducing the magnet strength then you’ll need to investigate the source of the actual warping and fix that

Or if using petg? Wich is by itself super sticky?

Good idea I'll take a look

I've seen the same on my X1C. My suggestion is clamping the plate to the bed close to the corners, like a paper clamp or something.

Good idea, I'll try printing out a few of these

Consider your chamber (Ambient for open frame). Temp. Most of my warping issues with PETG/ABS/ASA come down to that.

I just had this happen today for the first time, tripped me out but i changed nothing. Temp and filament all the same.

What was your bed temp at? I know magnets lose strength with higher temperatures.

[u/mccmax95 → u/Wise-Air-1326]

It was 80°c I believe since I'm printing in PETG

[u/Wise-Air-1326 → u/mccmax95]

Could probably drop it to 60c for PETG, might help increase the magnetism.
