Well where do you start, I’ve had one of these for 3 months, never have gotten a single print from it. I am not new to this, I have been printing for about a year and a half.
I had planned to go 24v on the bed but the 400 dosn’t have the capability only 12, what I noticed was the wire to the bed got hotter than the bed, so I replaced the 14 guage with 12, still got hot so I paralled another 12, it runs nice and cool now. The next thing was to turn up the power supply to 14.8v (as high as it went), now it will get to 60c fairly quickly, and I think it will get to 90c. You can try to use 24v on a 12v bed with PWM, but the MOSFET will overheat, not to mention the wire that already overheats will cook.

Thats just the first item, I will add more later.
