Can this be installed under the bed (near the wheel)? I want to use the solid rubber pieces (instead of the springs) and by the looks of it, this is installed at the bottom of the spring.. which compresses the spring more in the front? Not sure if it will work without springs...

Here's my cura start gcode for this. Uncomment G29 if you want to have a BLTouch or similar and and want to level before every print. Also you may need to tweak coordinates a little bit depending on the height/position of your brush.

question, I have the ender 3 pro with the magnetic bed and that magnetic plate has a lip that extends about 14 mm and it is 108 mm wide. will this hit that?

Yes. It is very close to the front of the bed. Works well for glass beds.

hey really nice remix!!!
