@Eclsnowman I have a 1mm piece of aluminium above my 12v mat and gets to 100 degrees in a, few minutes.
In the future (and I’m surprised more people here don’t know about and aren’t on) http://makexyz.com
@Tim_Rastall when I had it above the plate heat up time was similarly quick. But I was breaking glass with the quick heat up time.
@Brigham_Valdez I had a lot of tension on the corexy belts that are affixed to a vertical wall on my cart. This time I will add an aluminum xbrace to carry the load above the carriage and steppers across to the other belt mount points.
