[Gulfcoast Robotics] Borosilicate Glass Bed with Low Profile Mounting Clips for Creality Ender-3 / PRO/Ender-5 3D Printers - 4mm Thick

Nice rounded edges, a little expensive for what it is but I didnt have to look for a piece and cut it or have it cut. It is smooth and the clips work well on the ender 3. Glad it doesnt have a texture or a coating. I thought about etching or sand blasting one side incase I needed a rougher surface.

Although the glass was quite as warped as my Ender 3 Pro's bed, it was still warped enough to not level out completely. I ran leveling a g-code several times on each side of glass and I just couldn't get it dialed in. The center was either too high or too low. I ended up just getting it close enough and then I utilized the manual mesh leveling feature in the newer firmware I flashed, which compensates for warped surfaces (somewhat). So after fooling with that and running the 9 point leveling program several times, I was able to get first layer down nice and even, so I rolled with it. Several layers later the parts came unstuck and fouled the whole print up. I had cleaned with alcohol and wiped with micro fiber prior to every attempted print after that with the same failed results. I tried setting bed temp at 70° for PLA as suggested and increasing hot end from my usual 190-195 to 200-210 for the initial layer. That still didn't help any. So not only did I have to continue using the mesh leveling with this glass as I did with the stock surface, I couldn't get prints to stick. This is something I wasn't used to because the magnetic removable surface on my printer never had a problem with adhesion, even with bed temps as low as 50°. I'm not a fan of having to crank temperatures on an already warped bed just to have it not stick anyways. No way would I ever trust a 12+ hour print on a glass bed. I'm not big on the idea of having to use hairspray or glue sticks either, especially after dealing with ease of print removal and adhesion with the stock magnetic surface. Is the Ender 3 Pro's surface perfect? No... but neither is this glass plate. I gave 2 stars because it was cut nicely which made it fit perfectly over aluminum bed and it has nicely rounded corners . That's about it. In the end, I returned this glass for a refund and I just ditched the mesh leveling feature, as it was taking up unnecessary space on the board for minimal benefit. Now I just run a basic 5 point bed leveling g-code a few times every few days or so and I avoid printing in the center of the bed. Stiffer bed springs help keep it level significantly longer, so I do suggest this upgrade to the bed at the very least. Another tip to keep your magnetic surface looking new and not all scratched up is to use a razor blade to gently separate parts from the bed instead of using a blunt tipped scraper that just digs into to surface and leaves deep scratches everywhere. Anyways, I hope this helps someone else struggling with this warped bed issue that seems to affect 99% of these machines. These are excellent printers for the price but you should probably expect to deal with a few quirks in this price range.

I was very happy with the outcome of prints using this bed. It is so much better than the stock one that came with the Ender3. The bottom of the prints are coming out extremely smooth and far superior than previous prints. By far the best upgrade I have done on my machine.

The glass bed itself is great in my opinion, but the product description is very inaccurate. It didn't come with clips like it says on the description and the product photos.

I purchased this glass for my Ender 3 Pro. It is very nice, and makes the glass side of each print look very smooth. My prints do not stick to the glass as well as they did to the magnetic bed. I have had more success if I clean the glass with rubbing alcohol before each print. I would purchase it again.

Great product!! I can’t express enough how worth it this upgrade is for anyone who does not have a glass surface on their Ender 3 print bed

I love this bed. The edges are very nice and the clips are excellent.

Out wasn't perfectly flat. On top of that, there's no coating on it to promote good adhesion. You'll need to use something to help the government stick to the glass
