We are proud to be able to offer this ultraflat magnetic bed for the Jubilee Toolchanger 3D printer. This high quality products is manufactured by Mandala Rose Works. This magbed is machined from 1/4" K100S Cast Tooling Plate and is additionally ground to sub 0.2mm tolerances. In fact, the first batch has all tested out to be .02mm to .076mm overall flatness!

This is a top magnet designed bed. The 9 high temperature (150C) neodymium magnets N48SH are recessed into custom milled pockets on the top side of the bed, to keep them as close to the flex sheet as possible.

With the Buildtak Flex sheets, we see enough holding power laterally that we can actually slide a printer. Please note that flex sheets vary in magnetic strength, depending on the material and thickness used by the flex sheet manufacturer. 

Each bed is tested on a granite surface plate prior to magnet installation to determine the flatness after grinding. That value is then engraved on the beds for your reference when building and tuning your printer!

The magnets will likely cause interference with the bed probes. If using a BLTouch, please use the plastic tipped BLtouch bed leveling probe, and avoid probing directly over the magnets. Due to the flatness of our beds, a 4 point mesh leveling probe between magnets is all you need to do before printing. 

IMPORTANT NOTE: If at any point you decide to remove the magnets, first of all, when reinstalling the screws, turn the screw backwards until you feel the threads in the screw jump the threads in the bed. Once you feel that little bump, turn the screw in until it gets to the "screw stops turning point" with zero strength behind it. Once the screw has stopped turning, tighten it 1/32nd of a turn and NO MORE. Over tightening WILL shatter the magnets.

This part is machined to Joshua Vasquez's specifications and assures a good drop in for the Jubilee Toolchanger 3D printer, and it has all the latest features for accessory mounting.
