When using another slicer such as KISSlicer, it doesn't move the bed down the .3mm before printing the first layer (at least repetier says).  This realization came to me after every KISSlicer print I made stuck to the bed, and every Slic3r one had warping. I was about to give up on making slic3r prints stick!  I still set my Zstop and level my bed using the paper and thumbscrews, but unless the nozzle is right on top (scraping) the bed, the first layer will be slightly more than .3mm thick when using Slic3r. I toally get what you're saying about not trusting the software to do that stuff, the issue is that if I were to adjust the hardware as needed for Slic3r (manually raising the bed another ~.2mm), other slicers then are way too close to the bed when extruding the first layer.

That's just my reasoning for it however, and there are usually many more ways to solve a problem than one.

I always use leveling screw and Zstop screw to get that paper thickness height.
and yes, i ran into that problem with glass too... (before it snapped) poor glass quality... that's why i never try thicker glass... but I don't see people with thicker glass complaining about glass chipping away..

In slic3r go to Printer Settings -> General -> Z offset:, and change the value to -.2 or something close to that.

Once this change is made your first layer MUST be thicker than the offset value, which isn't a problem if using the Solidoodle default profiles (.1mm profile has .3mm first layer).

on which layer are you experiancing the warp/ lift?

I plan on sandblasting them with a bead blaster. I have zero desire to etch with chemicals.

Anyway, I like the mirrors because it's fun to see the extruder extrude....

I think I paid, two bucks each? I did pick up a sheet of bora glass that I plan on etching for use with non ABS filaments.

Thanks for this! I had been reading about people using glass but wondered exactly what they were using, I'll snag some binder clips from work as well


If you can't make it, steal it! That's what I always say. Just kidding.

Oven mitts work well for removing the glass with the print from the heated bed. Plus they look cool.  I went with a slightly more expensive route and got 8x8 borosilicate glass sheets. You don't generally have to worry about heating and cooling rates under 150C with this glass. (No shattering glass from thermal shock) http://airwolf3d.com/store/products/bor … ass-plate/ (I am sure a quick google could come up with cheaper pricing)

They are also like 10 times the price. I think as long as you don't have any little kiddies around and you don't mind running the risk of having some glass break, whatever you get from Joann's should be fine.
