I do this.
I don't use the "kitchen silicone mat", tried and it's a crap solution. It is too thick (1mm) and comes with 2 major issues
- takes too much time for glass to come to temp (insulation)
- it's not really that sticky...
originally I assumed "that's that" and after I had my second XY slip as the whole glass moved I removed the darn thing and went back to swiss clips / post frame clips.
Then, my order of 0.5mm silicone pads for heat sink mounting arrived and this silicone, while thinner, have a completely different feel in your hands so I used few pads for the glass on one of my printers and WOW!!!
insulation, there's ZERO time difference of glass getting up to temp with these silicone pads (I covered the whole bed, ppl often do it in checker pattern, dunno why) and when glass is directly on the aluminium held with clips
this thing is sticky, when cold there is no freaking way you can move the glass in XY, and after the first time you heat it to 100C it behaves like double sided tape, glass is held firmly to the aluminium, when you want to remove the glass you actually need to do it slowly and using spatula to slowly release glass from the silicone pads. So removing the glass is possible, but it is not easy, takes me at least 5 minutes to remove 230x230mm glass from the printer
since I rarely replace glass this works great for me, I have printbite on top of glass that releases prints fully and there is no need for any coating of the print surface ever so the only reasons to remove the plate would be to:
- put another print surface to start printing while old one is getting cold. This one I "solved" by adding 4 big 12cm fan's that I turn on to cool the plate, the print is released inside 2 minutes
- put another print surface to print different material. the only thing I don't print on printbite is rubber, everything else (all the way to nylon) print great on printbite but rubber sticks too good and is not released afterwards so I print rubber on clean glass without printbite, but it is not a big deal to spend 5min to remove the plate as I don't print rubber that often
