They are drive up only (and I think that is meant for books). I would like some part of it to be milled by the low rider, to continue the generation aspect of my machines. So NBD.
Regarding the spring steel sheets. I have a no name one that is totally junk. It just doesn’t stick well, even at high temp. It is supposedly PEI, but I think it is just paint. So I’m a little vary of some of the cheaper offerings. The one I have that I like now is from th3d. I have a textured one too, but it doesn’t stick as well, and I think it is because the bl touch is so sensitive it feels the peaks and valleys and the height gets all messed up.
Maybe with the cork, and a short pause before prints, the fysetc one will be heated evenly enough to work. It seems worth a try, and it is in stock.
Those photos are really helpful. I am looking at the cad, the bom, the comments on openbuilds, and the few photos there. I am piecing it together, but these help a lot.
What orientation do you print the extruder mount?
I’m having trouble finding the 1/2" square aluminum too. I can find 3/4" at the home depot. Or 1/2" steel. I might have to cut a big piece of plywood from leadscrew to leadscrew. My big concern there is that it might be stiff, and bind the Z.
