Taz 5 PEI Plate Bubbling?

Post by GoldPhive » Sat Apr 18, 2015 5:06 pm

The bed of my taz 5 has began to form bubbles or "air pockets" all over he bed. these pockets are effecting the part adhesion to the bed drastically and causing the prints to detatch from hte bed. has anybody else experienced this? what should i do?

I haven't experienced this on my TAZ, but have seen it on my other printer. My problem on my other printer was due to the adhesion of ABS... or really removal of parts due to the super adhesion to the PEI.

Lessons learned, I use a mixing spatula or anything with a blade to get under the project. Then slide the blade around underneath until the part pops off. Also use the Z-offset in slicing software to help with less or more adhesion.

Anyway... if you're bed is bubbling up, probably need to buy a replacement sheet from McMaster-Carr and re-apply with the 3M 486 double-sided tape. You'll probably need to scrape the od adhesive off the glass... There's a good tutorial on how to apply the PEI sheet stickied somewhere on the forum.

Can you post a photograph of your current bed?

Sorry this took so long. On top of this issue, I just had a replacement extruder come in about a week ago and it just clogged on me on a 48 hour print. GRRRR I'm sick of all that constant issues with this printer.

That is a small amount of air between the heater and plate. Not sure it's a problem unless they get really big. I would just monitor it over time, you can also push on the back and probably get the heater to re stick in those spots but only use your fingers, nothing hard or sharp.

so If lets say the bubbles have gotten bigger what do you do? I have tried to rub them back in but they just keep making a popping noise and come back. Please help it is causing so many of my print to fail.

On my TAZ 5 the bubbles aren't between the heater and the bottom of the glass bed, they are between the PEI and the top surface of the glass bed, because you can feel them. Mine have been getting more numerous and larger.
