I don't know if I should start a new thread or attempt to hijack this one.
Anyway, I have a problem with my heated bed. I believe it is drawing to much current from my PSU. After running it for a bit, I saw some "magic smoke" appear from behind the printer. I pulled the plug and saw that one of the PSU plugs had melted. I felt the wires and they were very hot (the wires going to HB-PWR on the RUMBA board). Luckily no melting on the expensive RUMBA board. Am I correct in assuming that this heated bed i purchased (a very cheap no brand) has too little resistance, thus causing high current draw from the PSU?
PSU is a very cheap generic one for a PC although probably does about 400W. I don't think this is the problem though because i have a second printer running fine from a even cheaper PSU, but a more expensive heated bed.
I am thinking about just buying from a more trustworthy source a second heated bed, unless someone could help me solve this problem if there is a simple solution.
Thanks
