Prusa Mini Silicone Bed Leveling Mod  

RE: Prusa Mini Silicone Bed Leveling Mod

I ended up purchasing a box of 50 or so from McMaster-Carr, hopefully I'll find other projects to use them for.

Anyone know of a good US-based supplier for the 16mm M3 Torx screws, or a hex screw that is compatible with this mod? The screws in the amazon link in the GitHub repo are not currently available.

I had a lot of issues when printing larger things because my bed was crazy warped. I think I got it pretty well now 🙂

Hi. Just started on the bed leveling journey. I have a question; when running the G29 code, do you run it on the heat bed, or with the print steel sheet on? I get different values with the smooth sheet and the satin sheet...

I always put the smooth sheet on. I don't think it matters as long as you do all the adjustments with the same sheet, and I'd choose the one you print with the most.

The sensors on Prusa machines are (I believe) designed to test distance from metal, so the heater bed PCB will be inconsistent in comparison to the steel sheet on top.

Put the sheet on first.

In the menu you can set the type of sheet you have put on and save the z-offsets for each specific sheet. So if you switch between the sheets, all you gotta do is change the sheet type and the printer adjusts the offset accordingly.

yep, the smooth and satin sheets (and I'd assume the textured, but I don't have that one) are different thicknesses so have different results for z height.
