I just ran a test on my bed heating speed with my modifications, I can get from 21c to 60c in about 6 minutes, it got to 88c in 16 minutes and had a heat fault, so it will get to 90c with a marlin modification, I will probably put in a 6v supply in series for the bed, turn back down the main one to 12v, if I ever get this thing to run!
