Actually I’m pretty happy with the results while printing pla on a buildtak surface, not with abs. Velleman says you can print abs on it but I’m not convinced, never did achieve repeatable successful prints…
Most of the time, i fold a piece of 80g paper in 2, and use that for height calibration. Most of the time some finetuning is necessary, sometimes I stop the print and adjust the setting screw on the back 1/8 - 1/4 of a turn, or I make the adjustments on the go with the setscrews on the bottom of the bed while the printer is still printing a skirt.
It’s been a while since I used buildtak, but was quite happy with it so i bought another one to replace the first. I tried to print ABS without a heated bed but the abs just doesn’t adhere good to the buildtak when its not heated. You can also use the sticker with a heated bed, but one time i tried to loosen a piece which was quite high and had a small base at the bottom. No issues there as the print was fine but when i tried get the piece of the bed, a bit of the sticker broke off and was stuck on the print. The sticker had seen some abuse at the spot that broke though,.
My personal conclusion: It’s great but its not ‘the’ adhesion solution as it is advertised. But you can do nice things with the glass without the sticker on it.
I have added a plexi front door and roof to my Vertex, it protects mechanical part from dust.
I’m looking for filament dust protection to be placed directly on the printer, I can’t found it on Thingiverse so I’m thinking in design it by my own… and share it of course!
