Sometimes 110c is too hot! drop it to 105c and see how you go, also you could be printing too hot - drop the nozzle temp a little too. If you print too hot, when it cools to 110c its warping because like anything that's hot that cools down, it shrinks - the idea is to find the balance.

Checkout these pictures - kapton tape, stock hotbed.

All I can say is level that hotbed, and when you have done that - Do it again! trust me.

First picture - I can print full size 450 quadcotper arms, edge to edge without raft - and no warp at all. I CANNOT do this on a glass heated platform, I just cant.

I print these at 105c hotbed and 225c nozzle, if it was white 108c and 228c nozzle.




An the second example - a 5mm thin hollow wall with 200 divets in it (I made beado trays for my kids) Printed 15cm high, no warping - no curling.


Warping problems, been there done that - solved it.
