I use borosilicate glass I got from Amazon for $10. I use hairspray and in 6 months, I've never had a print come loose. I never use brims either. I think the borosilicate glass is also tempered, which means IF you break it, it will break into little pieces like side window glass in cars and it won't cut you.by tjnamtiw - Reprappers

You have to put absolute positioning before your homing command. G90 before your G1 X.... Y..... The way you have it now, you are telling it to move 220 mm MORE in the Y direction. And it says "Say what???"by tjnamtiw - Prusa i3 and variants

My hotend has no problem getting up to temp, but my glass plate won't go above 108.5 C. I do see the heat board slightly bowed, so I do plan on remedying that tomorrow. In the meantime, would a 7 degree heat deficit be enough to prevent a print from starting? I have successfby tjnamtiw - Prusa i3 and variants

Quoteflatlander Quotetjnamtiw True, but why wouldn't FT know the shrinkage of ABS and compensate? No excuse from a manufacturer of the product!

Even if your 20 mm cube is perfect, I discovered thanks to the guys here, that there's one MORE step after that. Go on Thingiverse and find a single thickness test piece and slice it. Look at the GCode (select verbose if using Slic3r) and see that the wall should be 0.48 mm. Now run the part and carefully measure the top row or two, no more. It's probably well over 0.48 mm.

For 6 months, I've been strictly running PLA. Today a threw a roll of ESUN PET up there. It said the temp range was 230 -250, so I tried the 230 while running my single wall test. The thing came apart like a SLINKY. So I upped it to 240 and got my test piece to stay together no matter how hard I pulled. I also got wall thickness of 0.49 to 0.52 when the GCode called for 0.48.
