They have a good selection of sizes some are designed as high temp boards and some are rated at 24volts. May be worth looking at . thermistor and prewire options extra.

If you decide to go this route please take the time to understand the risks.  I would be more than happy to walk you through the process via PM.

You can...but you will need to get a DC/AC SSR to control it...no big deal as long as you're comfortable running 110V into your print area...

First I would try the PID tune as elmoret suggested.

Doesn't look like bed failure to me (assuming that screenshot is at 12v), looks like the new firmware has different bed PID settings.

Probably should re-autotune. Also could be more airflow across the bed, if you changed fans.

The screenshot was taken while running 15v. I will do a re-tune at 12v and see if it helps any

As am I!

I wish I could get by with only heating it to 110; it would really cut down on my heat-up time.

I'm not going to damage anything by running the bed at 15v, right? It seems to be about 1 ohm, so when cold it draws around 14.5 amps at 15v.

EDIT: Corrected my math

I suppose it might stick around 130. I'll give it a try

140C is Airwolf's recommended bed temperature for polycarbonate

That's really hot for your bed.  I see no reason or need to run it past 110 and most run 100-105.  Can I ask why you are trying to run it at 140?
