Going to upgrade one of my robo3d's to an aluminum bed. Couple things I'm not sure about, what kind of aluminum should I use? Is 6061 T6 ok? How thick? 2.5 - 3mm thick? ( 1/8" probably? Bed heater? No idea what to get. Also planning to change to this IR Sensor https://printedsolid.com/collection...cts/mini-ir-differential-height-sensing-board I assume it will work on aluminum? if not I have these also https://www.amazon.com/gp/product/B008FZC8F2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Was printing a mount to velcro my amazon fire TV up under my TV. Printed in PrintinZ PLA/PHA filament. Bed was fully cool ( cooled all night ), this happend. I have a Fleks3d plate i can put on for now. This is what I was printing.
