It might be a small area that's disconnected inside the pad. So it seems to be within the threshold of not overheating the silicone itself. My temperature was only peaking at 65C, so the current was too much at a certain point inside the pad which caused the burning and melting. I doubt it's software. If it's constantly at 100% power output and it was fine up until 88.3, then most likely a bad heat pad and I would send it back if you don't mind losing your machine for a few weeks. You can also upgrade to a better heat pad if you are comfortable in slicing the harness and taping the new pad to the bed, etc. But that voids the warranty. There's really nothing you can do for a bad heat pad, except for replacing.

It could be a bad heat pad. Mine eventually burned through the silicone pad because a wire inside the pad was severed. Look for burnt marks near the power/thermistor harness entering the pad underneath the bed to see if your pad is slowly overheating. 88 should be ok to print even if you don't reach 95. To bypass, go to printer configuration and manually set your heat bed temperature to 88 and the print will start.

I looked below the print bed and saw no physical signs of any issues. Do you think this is something I may need to send it in for, or should I just try to use it at 87-88C, or even better, do you have any ideas for ways I could easily fix it here. Weirdest to me, is that once reaching 88, it will hover back down to as low as 87.1, and get up as high as about 88.3, and somewhat cyclically fluctuates between the two. Similar to the extruder at it's desired temperature. The temperature is definitely set to reach 95, and the power to the heater never dips below 100%, but still it makes me wonder if it is possible that it could be a software issue, though I doubt it.

Let me know how it turns out. *Three weeks ago* I filed a similar problem with SD, and help so far consists of "are you still having trouble?", and asking is there's visible damage to the pad/wires.

So let's see - I can't start an ABS print, and I can't finish a PLA print (it jams).
Sure it has a nice feature list for the price, but I paid for an actual printer, not a list.

I got my soliddodle press about 30 days ago ad have had no luck with it at all. I've had tons of different problems with it. Right now my trouble is that the bed wont heat up enough. Soliprint wants it to get to 95C, but with full power, it only heats to about 88 before plateauing, and then it will hover around that temp. Consequently, prints are not starting because the printer is not heated all the way. Is there a common fix for this type of problem?
