I just fitted the Modular bed and made new stand offs now im using the bed I also have a sag approx. 1mm at 60deg I have this fitted to the Taz 6 I was going to make new printed corners taking the 1mm off instead of the 11mm stand offs, is there another way to stop it sagging.

I finally got tired of the uneven heat. (bed set to 110, reads with heatgun 75) and used a sheet of the 3M adhesive and stuck the steel to the glass. Now it gets to 110. Debating what to do with the second modular system I have on another machine.

What I have used on my Ender 3 printer was a thin silicone thermal pad on top of the aluminum heat bed and then placed the glass on top of it. It works great and has very good heat transfer...cheap too!

I want to try and level the bed on my Taz 6 but haven't decided what to do. I now have a bl-touch on mine and the bed is very tilted(high on the right side). I guess the first thing would be to print some new bed mounts from nylon and raise the left side up to compensate???

In case anyone is wondering, this is still an issue. I just received the new etched modular print bed heater today, and these photos are during printing. To be fair, I'm printing the new bed corners, so I guess there's an arugment that it might get better once I install it with those, but I've also got the bed set to 120 in the hopes of projecting a little more heat up to the glass.

I'll probably try flexing the steel back the other way a bit to see if I can flatten it out, and maybe put something under it to help hold it up, but it sounds like some 3M adhesive might be the way to go.

The corners didn't do much to fix the issue. The heater was just sagging way too much. I've just propped it up in the middle, so it's working, but this definitely seems like an issue that should be addressed in the design. Or ship the part with a spring to put under the middle.

they should read this thread and give details of the stand off< I did contact them and they seemed to be vague about this issue> LULZBOT if you reading this you don't credit yourself with such a product that clearly has a design issue..
