Leghk, good info.  This may be a future upgrade.

As for my problem, I lowered the temperature to 60C on the bed and it worked perfectly.  I was surprised by this. In fact, it was it was hard to get off the bed in the morning.

So, no painters tape needed for now but I wish I could say definitively what was done to make it start working. Maybe it is my healthy living.

I'm curious... what were you printing. I can't really tell from the photos.

No heat, room temp = ~ 65F

first layer @ 30mm/sec.

on blue painters tape, a piece of 20lb. paper for gap.

My prints do not come off easy nor do they come off by themselves.

[Edit: of course I re-read and realized that you're discussing PLA on kapton; never mind me!

I did try the acetone.... no luck.  Here is what it looked like at 180/80 a few minutes ago.

Trying again with with 60 bed temp.

I think a lot of people mix it with failed prints to make a glue then smear a light layer on the glass.

Worth trying?

He was working with blue PLA extruding at 195 and 50 on the bed. Parts started coming off the bed about layer 5-100.

I changed the Z axis adjusting it down and changing the Temps to 180 and 80.  With the new Z, it printed a flat extrusion on the first lay but still came off about layer 8 (in the middle, not at the corners like from warping).  I stopped the print, and the part came off very easily.

I adjusted the Z axis another 1/2 turn.  This is maybe too much as it was scraping plastic to the sides of the model and pulled part of the model off the bed after about 3 layers.

It is the original bed and has seen some use.  Do they get slicker with age?

We've tried hairspray with not much luck.  What do you all recommend trying next?
