I have had a glass bed for a long time but never replaced my (non-glass) existing one. I have been trying to print a few things for a couple of days and I was getting issues with it attaching to the bed and with some very careful observation and pics I saw that my bed was disforming under heat.

Well. I already have a glass bed. Its been sitting around for a while. Yep, when dealing with other things I dive into projects and work so that is what I did. I found the glass bed in storage, printed the brackets and ripped the old bed apart.

I used rubbing alcohol to get rid of the glue (I should have gotten some googone or whatever that is called) with disposable gloves. It probably took me around 2 hours (I let it soak for a long while) but I did use a scraper so the bed is not "shiny" as it would be, not that I care if it works.

The end result is working well. I am getting better bed adhesion and my prints are turning out better. Though, at this point I feel like I have either modified or replaced like 70% of this printer. At some point I will buy another one but maybe I can get this one to a makerspace or something to let other people learn how to hack this shit until it works the way you want.

I will probably do a followup with some videos of prints or something but this is what it is for now.

Pics are probably out of order. You get the idea. Some are of the original bed, some under it, some with the glue, some with the glass and such.

The poal image upload hated me because I guess my images are too big? Ill look into this. See the image posts below....

The glass bed is something like this. Mine has been sitting around forever so it does not have the corners cut. Its Borosilicate. https://www.amazon.com/Borosilicate-130x160x3mm-Polished-Monoprice-Printers/dp/B07FRK6TZX

I had to modify things but this is a basic tutorial for my printer. However, I removed the original printing surface since it was warping under heat and also had to spend a lot of time removing the glue. https://www.instructables.com/Adding-a-Glass-Bed-to-a-Monoprice-Maker-Select-Plu/

The filament I am working with is a flexible TPU. This is the specific one I bought. I did do the mod to fix the printer tonight but I am printing a benchy to make sure I don't need to re-calibrate before trying to print the TPU again. Its currently printing now and will take a while. https://www.amazon.com/dp/B0CP213ZMG

Okay, now I'm with ya. That term Glass Bed was throwing me off. It's a glass build plate. I did not know that such an animal existed, I will have to look into that.

As far as I know all TPU is flexible, that is the draw to it. I use it quite a bit for making gaskets and shit that I want to have "grip". Also, it's tough as balls so you can make really durable shit with it. So far I have not had any trouble printing with it unless it gets any moisture, then it sucks. I dry the shit out of it and I have had real good luck. Also I spray my build plate down with my wifes fancy hairspray and that helps.

Yeah, I know the tricks but its about the feeding system. Ill post some more info sometime this weekend (even if it doesn't work). My entire point is to print a gasket and my printer was not working for it. I have modded the damn thing so much I kind of refuse to let it NOT do something if I want it to.

The "glass bed" has been around since the early days. I do use "Aqua Net" hair spray to make things adhere better (after a proper wipe down with rubbing alcohol). I don't even remember when I bought this printer it is probably around 10 years+ ago at this point. I have modded so much of it that I don't know if you can even consider it the same printer anymore.
