Insta,
Thanks so much for these. Mine is working great!

Quick update - the 99% alcohol did the trick! Sticking like the day it came in.

Finally got time to set this up and make a few prints this week. Works great!
A couple things I encountered:
- The surface temperature was about 10C lower than the set point for the heated bed. Turned out my heated bed sags a bit in the center, so I put some thermal paste between the two and the temperature is pretty accurate now.
- Occasionally a small layer of the print gets stuck to the PEI; the first time I saw it I thought I managed to jam the nozzle into the PEI and melt it, but after hitting it with a scraper it turned out to just be leftovers.
- And yea, I turned down the acceleration because my table started shaking a bit more with the heavier plate. (I was still using default).

Otherwise, sticks great and is pretty much indestructible.
Thanks insta!

My bed sags as well, but I have no way of measuring the actual temp - may need to grab an IR thermometer or something to check it

grab an IR thermometer

Remember that IR thermometers:

• Assume an "organic" target: you get incorrect results from bare metallic surfaces like aluminum plates. Always apply tape to the metal as a target and verify that "room temperature" readings make sense.
• Report the average temperature of a circle in front of the opening: the laser dot serves as an aiming guide, not a pinpoint target. The circle embiggens with distance: about 1 inch at 6 inches, 2 @ 12, 4 @ 24.
• Can't measure the temperature of anything smaller than that circle at any distance: hot ends and transistors are too small.

A Public Service Announcement for anyone reading this discussion thread in our future ...

Nice usage of "embiggens", my favorite, perfectly cromulent word.

cheers,

Will this completely replace boro glass or do you pull it out for specific jobs? I am currently using boro and hairspray which is easier for me than kapton tape.

Ordered. Hoping the PEI layer lasts for a long time. How much time can I expect out of the PEI layer and can it be removed and a new sheet reapplied?

If you don't do stupid stuff with it, the PEI should last for a very long time. My first PEI bed got some small nicks in it where I was trying to pull parts off while still warm, and also some from where a razor blade flexed. I haven't added any new nicks for a long time. I recently removed the PEI, cleaned it up with acetone, and will put the sheet back down with the nicked surface down one of these evenings.
