Can you post a link? Cant find anything using those numbers....

Thanks

Bed is not here yet but when arrives I will be busy for a short time and throwing the XYZ level devices away too!

I didn't break the glass, the heating coil had gone open.

The only other leveling Ive done is with the XYZware and hated how long it took to run through the test. I use an -0.05mm z offset in slic3er. The three glass plates I purchased from McMaster were very close in thickness so they could be swapped without re-level. Sometimes I need to lower one point by 5-10 deg when the print starts.

I decided not to flip the heat pad because the leads were offset from the center and would have require removing some of the bed frame. I removed the Da Vinci leveling metallic strips and simply placed the new glass on top of the cracked glass. I did place some fiberglass insulation under the floating bed because I thought there would be some power issues.  I'm running now and the bed heater its averaging around 25% power at 95 degrees C. 

The Bottleworks design is cool but seems a little expensive. I used four printed parts that I will see about posting on thingaverse, four compression springs from a home depot assortment (4$), 1/4" Aluminum rod HD (6$), Loctite plastic epoxy HD (5$), and the 1/4"x9"x9" borosilicate glass was 25$ from McMaster-Carr.

The design is simple. It just two angled surfaces that hold the plate down and stop it from sliding. The front piece is hinged so that it can easily be removed and also hold different plate thicknesses. The hardest part of its assembly was epoxying the parts on the Da Vinci bed. I used the new glass to align the back piece while it cured then with a smaller flat piece for the front. The aluminum pin and springs just slide in.

The swappabilty really saves time. Still have to wait for the new glass to warm up but it isn't much longer than the stock bed.

I made a video of me switching the plates but cant figure out how to post the url. Search youtube for "Swappable Glass on 3d Printer Bed".

there were several Makerbot owners that switched to it.

I'd love it if you'd share the parts - or better, put them somewhere public for use! I tend to use thingiverse.com a lot; seems like that, or one of the other public sharing spaces, would be a great place to have this shared for folks using the Da Vinci printer.

I'm actually in the midst of repairing / replacing my own cracked bed and considering shifting to a PCB heatbed, but I would welcome this if it's a viable option as well. The swap-out seems like a great feature to have!

What do you use for levelling, I don't see the levelling bits anywhere!

I am only asking because I am changing my hotbed to a MK3 and I was wondering how I could incorporate levelling with it.

I decided to keep the cracked and make a mechanism to accept new glass on top of the old and also make it possible to have multiple pieces of glass to swap after a print to save time on cooling down in the printer and removing the glue stick residue. The system works well after a few redesigns. After breaking some cheap plate glass I purchased some 1/4" borosilicate glass cut to 9x9". I went with the thick sheet to avoid any more breaking of the glass.

Working 100% Now. I can post the parts if anyone is interested.
