Hi,
I'm having problems with ABS parts lifting.. I've tried blue tape / glue / hairspray etc.. however I believe that my bed temperature may be low... Measuring on a Fluke 187 it reads only around 70 degrees at the highest setting (120 degrees) That's measuring the aluminium at several points.. from the top. When in simplify3d.. I can set 140 degrees and switch the bed on, and I can then read around the 90 degree mark..
Testing this theory I printed something while at the same time blowing a hot air gun on to the bed.. and it was the only print that actually stuck and came out well..

I've also covered the sides/front and a little of the top with foil and ambient temperature is around 40/50

Has anyone else had an issue like this?

I'm considering buying some Buildtak but if there's a problem with the bed temperature then I'd like to fix that first.. The parts that have been lifted have all been printed with rafts too.. I've not tried without rafts yet..

Any help. greatly appreciated!
