What's your bed set up?
Has anyone been able to print on the aluminum without any tape, glue....? I've tried a few ways and find a painters tape bed sprayed with 3m adhesive is the best for me. Diluted wood glue works as well. The only tape I have is Scotch Blue (the good stuff I used for painting) and find that if I scuff it with steel wool it works better. I haven't tried the cheap stuff yet. I am in the process of installing the heated bed but it didn't make any difference in pla sticking to the aluminum. At the moment the heater is there and running off of a separate power supply but it's not plastered to the original. It's running about 55C. (Different issue there as well).
So the question is "What do you use?" for your prints as a print bed? I've read that glass works well and could have a piece cut but figured I'd ask.
Is this a good question?
