GT42 Frankenstein

Ok so this time i'm being careful with the glass bed, i found some aluminium tape that i've used to try and improve thermal conduction. The alu tape is a bit thin so it still doesnt conduct the heat great but there is definite improvement. I'll probably stick the brim down to the bed when printing large footprint parts.

The most important part about the alu tape is that it allows the use of an induction sensor.

So last night right after initial power up and checking that everything is in working order i decided to see how hot my new heated bed could get, and never thought it through.

Glass doesn't mind high temperature, but glass does NOT enjoy temperature differential...

Turns out those little strips of glass around the edge of the bed was still cold by the time the centre of the bed had reached ±80°C and then BAM...

Self inflicted injuries are no cause for sympathy ;)
