Hello my name is Creghton, Im fairly new to the forums but not new to reprap. I plan on building a repstrap in the next few months and I've been researching parts and specifics. One thing i can't find is a good heated bed. I want to make my own with Ni-chrome wire on aluminum, but i can't find any wiring diagrams or anything like that. Also, if anyone has a better idea for a heated bed on aluminum please let me know. Thanks!!
