So I just ordered some glass for my 3d printer (I have a Flashforge Creator Dual Extruder Wood Case 3D Printer), and I printed out a z-axis shim so the glass wouldn’t hit. However, I noticed something, without the shim when I jog the z-axis, it stops right before it hits the bottom of the printer, However after I had homed my z-axis with the shim, when I jogged it, I was moving it down expecting it to stop, but it ran into the bottom of my printer. At the end of the print, the bed moves all the way down, I am worried that if I print with the glass, the bed will run into the bottom of the printer. My guess at how to fix it is to set a z-axis home offset, the same distance as the height of the glass (1/4", or 6.35mm). I wanted to get other peoples opinion’s on this however. Is setting a z-axis home offset the right thing to do? Please let me know. Thanks!!

Hi @CaptainML what’s happening with your z-axis stop switch? Is it actually meeting the shim? All the shim does is trick the printer into thinking the z-stop is sooner than expected (by the thickness of your glass) so as long as it’s lined up correctly and the switch meets the shim, there’s really very little that should be able to go wrong…
What I am trying to figure out is if I need to change my z-axis home offset. The shim stops it 1/4" short (It hits the z-axis stop switch) and the shim does trick it into stopping, but when the bed moves down all the way, it also moves down 1/4" too far, and runs into the bottom of the printer. So my question I guess is do I need to tell the printer that I am stopping the build plate 1/4" shorter so that it accounts for that distance (1/4") and so that when the bed moves to the bottom of the printer, it doesn’t run into the bottom. I guess I phrased my first question a little weird.
