> Could too much thermal insulation cause the bed temperature to lower (to avoid overheating chamber temp) to the point the print no longer adheres? etc.

I've insulated my Core One specifically to reduce noise, vibration, and improve high-temp printing and learned that:

1. When printing at high temperatures, you don't have to worry about overheating. Chamber fans are plenty capable of cooling the printer down.

2. There are so many nooks, crannies, thermal bridges, and gaps that modifying the printer to add insulation is a fool's errand. You will spend a lot of effort for little gain. If I were to buy another Core One, the only thing I would do again is damping pads in a couple areas to reduce resonance caused by the flat steel panels.

3. That being said, insulating the core one externally by covering it with a "jacket" of insulation or placing it in an enclosed(ish) space is very easy and effective. In an enclosed space, you need to make sure the chamber fans exhaust out, so they can retain control of the environment. You don't want it to be a fully closed system.

For point 3, these days I literally throw a beach towel on my Core One when printing high-temp filaments. It covers the top, front, and sides. This is enough insulation for 55C printing (the maximum allowed by hardware/firmware) and is easy to remove when I don't need it. Of course there are plenty of more suitable materials you could use, from textiles to foamboard insulation. But the concept is the same.
