Taz Magnetic Bed System

(parts are listed at end of this)
I have been using a auto level probe for while. At first I clamped a .4" thick sheet of aluminum with a 1mm sheet of PEI over it, using 12 clamps to clamp the the glass bed.
It worked okay but was a pain because of the clamps and the center of the PEI was a little flexible.
For the most part, the nozzle prevented any serious bow. I had to use a large 18mm inductive probe because the aluminum cuts the probe sensing gap in half. Then I tried a piece of steel sheet metal and was able to switch to a smaller 12mm probe and get the same gap distance. I have now graduated to a magnetic bed and am very happy with it.
The concept should work on any similar machines.

This is my latest bed for my Taz-enstein 4. It is a sheet of 285 F (141C) phenolic cut to 300x300mm on my slide miter saw. I routed 25 holes spaced at 60x60mm. The magnets are high temperature 3/8" x 1/16" N42SH. The metal removable bed is a piece of zinc plated sheet metal, 12"x24"x2
