One the right in particular, there is no room for anything. About 1mm clearance between the plate and the upright carrying the PSU too. Since y is the only thing that moves the glass, std pinch clothes pins have plenty of room fore and aft. 2, maybe 3 on the rear, and one or 2 on the front but keeping the left front corner clear should clear the initial head motions. > >> My 3D printers were fine with no retuning after I added some thick > >> borosilicate glass, > > Mine too. > I suspect at the speeds I have it running, 30 ipm or less, it will not be a problem. I scrubbed the glass with bar keepers friend as it wasn't taking water at all well, like it was waxed or??? But now its slightly cloudy with dried white school glue & lots of water mixed, so we'll see how the adhesion works. In about an hour as the last big part is about 85% done. I found I can't expand the bearing carriers enough for full engagement as the short plugins have expanded too much to fit in the bearings bore. That means I need to shrink the internal gear around 1.5mm if I want the bearings to give full engagement, then I still need to expand the flexgear so the bearing don't have to distort it near as much, currently the teeth are clearing each other at the hop-over point by nearly 2mm, way to much flex on the gear. All they really need to do is to clear, and this is a case where microns are all thats needed. More than that is just backlash. > >> I think > >> these glass bed upgrades are usually done without changing the > >> motor parameters. > > That's what I did --- nothing at all.
