Gee I guess someone forgot to tell my unit that because it's been working flawlessly for 3 straight weeks and I print constantly. I also have no problem running the bed at 115 C which is as high as I've needed it to go. I also ditched the relay for a SSR and went back to PID regulation because bang-bang sucks for anything with a short (less than several minutes) on/off cycle. I could really notice it during the first 2-3 layers using a translucent red PLA (Ingeo 4048D based) and you could see from the color changes from dark to lighter and back to dark synchronized to the clicking of the relay leaving a 45 degree 'zebra stripes' pattern on the print. It wasn't noticeable that much in the finished print but it was definitely a clue heat regulation sucked and there was constant expansion and contraction going on but the SSR and PID control cleared that up. I kind of figured going in that I wasn't going to like the bang-bang controlled bed
An aluminum bed and a good silicon heater are a better solution whether you use ABL or not ...... but it also adds costs and weight. This works for me, I'm happy with it for now. Granted what works on a 10 may not work on a 12", I opted for the 10 because 12" bed at only 12v is really pushing the limits
Please explain to me how to...
