Mounts by Printer Ender3
The best method of adaptation for the Ender3 series of printers is the hard mount the bed with a spacer at the front left carrier plate to secure the dock and move the Z-endstop switch to Z-Max. Moving the endstop eliminates the need to get Z-MIN adjusted to the final bed elevation. This has been successful with both Marlin and klipper adaptations.
The toolboard mount secures to the X-carriage plate and uses the top left roller screws and the M3 screw that secures the hotend fan cover to the plate. Due to the different production variations, a longer M3 screw may be required.
An alternate version is also provided for those who do not want to loosed the roller screw and only uses the M3 shroud mount screws. A hole is provided to insert a length of filament hold the probe wires in place.
The probe dock is provided in 2 parts and designed to be hard mounted to the front left of the Y-carriage plate. The dock mount is designed to use either M4 coupling nut or 1/2″ diam x 1/2″ high spacers to elevate the bed 15mm from the carrier. These spacers are commonly available at hardware stores and big box stores.
Adjust the height of the dock as needed to compensate for the print bed materials. Thin cardboard or fibre washers will help insulate the spacers from the heated bed. The remaining bed leveling screws can remain as spring balanced posts.
Print out 2 of the spacer risers and use them under the right side bed mount screws to maintain relative elevations.
A more solid installation if to install another spacer under the rear left bed mount at the cable-chain location without any risers.
