Re: Lulzbot Mini Print Quality worsened after firmware

>> I did save and restore the z-offset and e-steps from the calibration sheet. Are you sure you didn't restore the E-Steps for the standard extruder (original calibration sheet), instead of the Aerostruder? Default for Aerostruder is around 420 as I recall, which is much different than the Standard ...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

Just to follow up... I decided to go with a 0.020" thick PEI with pre-laminated adhesive available on Amazon. The install was quite a bit harder than with the stock 0.010" sheet. First, because the 0.020 sheet is stiffer it is more difficult to apply and get all the bubbles out as you gradually lay ...

Re: PEI Film Woes

Cool- For glass, Taulman recommends 45C bed with PVA when printing 910. See the link below for more details. The A910 is really great stuff - just make sure it is really dry, as any absorbed moisture will cause bad layer adhesion and popping/bubbling. If you have any trouble, Taulman is really respo...

Re: PEI Film Woes

The PEI sheet gets lumpy after a few prints Would like to replace it with solid glass print, so that prints always have flat botom https://www.matterhackers.com/store/l/glass-plate/sk/M9HHF5ZW?rcode=GAT9HR&gclid=CjwKCAiAsoviBRAoEiwATm8OYHXQdw6mTuF-6qefCFTa9ruJERw4fXJ-BWWFjltfEcJyTcbP4J410hoCCxkQAvD...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

Just remember to adjust your Z offset to compensate for the increased height of the bed. That isn't making sense to me... The washer thickness sets the distance from the PEI when probing. The washers sit on top of the PEI, so the relative distance between "probe contact" and "PEI surface" should be...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

@coparatech - Thanks for the links! I found a seller on Amazon selling a "set", 8"x8" of the 1mm/0.040" PEI and 8"x8" of the 468MP adhesive, so I think I'll give that a try. https://www.amazon.com/gp/product/B074XJLWL6 I wish the sheet/adhesive came "assembled".... The same seller offers the thinner...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

@coparatech - Thanks for that PEI link, I've wanted to try a thicker sheet and that looks perfect. What adhesive did you use, and was it sourced from mcmaster as well?

Re: First Time Printing With Nylon

If you don't want to enter everything manually, I recommend starting with Lulzbot's profile for Taulman Alloy 910 Nylon, then adjust as needed. The temps recommended on MatterHackers' site for their Pro Nylon look similar to what works for A910. Make sure to put some PVA-based glue on the PEI bed. W...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

Good info. So 9082 can take the heat, but may not adhere well to PEI if not designed for plastics. I really like the concept that Prusa has, with the spring steel plate powder-coated with PEI. No adhesive, no bubbles. But they've had significant problems getting production quantities of acceptable q...

Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

I haven't tried it... But 3M has another tape, 9082, rated to 280C for short term tolerance. The 468 is only rated to 204C for short term tolerance. I think Lulzbot will eventually be looking at this, but it appears to be out-prioritized by other work at the moment. https://code.alephobjects.com/T4401
