After I built my heated bed controller, it was time to create a PCB for it. Especially, because people had trouble to build the controller.
Warning: long article ahead!
As almost all my previous buyer built a heated bed controller, and at least Bogdan have built one, nophead is using his brain controller to handle the heated bed temperature. So there left no choice, but build my own;-)
It took me more time then I thought, but finally, I built my improved heated bed.
The initial test shows, the bed's temperature can go up to 164.3C, which is pretty hot:-)
(on the picture it only shows 148.7C, but it is because I already disconnected the transformers from
mains, so it already cooled for about 3-5mins.)
Its always nice to see how others are developing further your design.
This just happened: my previous heated bed buyer thought further the design.
He insulated the bed, and made a control-circuit for it.
It's time to update my version too;-)
