I've got my hic i3 metal frame auto leveling printer up and going. I'd like to add a Borosilicate glass plate, but I have a question on how to execute it since my printer has the SN0-4 inductive z axis sensor. With the addition of a typical 3mm glass plate I'm pretty sure when doing it's auto homing it'll not sense the bed and crash into the glass and cause major problems. Any ideas?

thanks

I ended up buying a cheap piece of plate glass cut to size from Lowe's. I unplugged the inductive z sensor and added the extra microswitch for the z axis. I was able to get the z axis limit switch homed in the good old way and it seems to print fine.

Yep, inductive will NOT work on a glass bed

See my post about the inductive Z sensor. You can get it to work by inverting it on the gantry and having it detect the smooth rod on the X axis. Works great once you find where to mount the Z sensor on the vertical gantry support.

I put my sensor there on the gantry using the spare z microswitch holder that was in my kit. It works great. Thanks for the idea mpoling.
