Mini Stealth DAB - Beta Release v. 0.8

This is a flexure based nozzle probing option for mounting the Mini Stealth toolhead in a Voron Trident or V2.4. It uses a simple linear compliant mechanism to provide ~0.5mm of Z travel while being quite rigid in the other axes. It weighs around 20g fully assembled with Z and X endstops. It should require the same Print_Start preparations as the Voron TAP to ensure a clean nozzle and accurate probing. While probing with a scale on top of the bed, it applys about 600g of force.

There are a few supports (shown in green) built in to make printing more reliable. After printing, the two inner sections will need to be gently, but firmly, pried apart from the two bridge sections while being careful not to plastically deform the flexures. There are four pockets for M3 square nuts to secure the Mini Stealth core piece using two M3x45 BHCS at the top and two M3x12 BHCS on the bottom.

There are several different rear boss pieces depending on where you have your X endstop mounted. This piece is secured with a pair of M2x10 self tapping screws.

Assembly:

• After ensuring that the flexure moves freely, install one of the grub screws in the top and screw it in just enough to remove the looseness in the flexure. This provides a known lower limit of travel.
• Install the Z_Stop_Boss with two M2 x 10 screws from the front.
• Install the Z micro-switch with the red trigger on the left (viewed from the back). The wires can be fed to the front through the lower gap in the flexure.
• Install the other M3 grub screw on the bottom of the DAB_Z_Boss. Screw it in until you hear the micro-switch trigger and then turn it back out until the trigger releases. This makes the trigger travel distance less than 0.5mm.
• Mount the x-carriage to the MGN12C carriage with four M3x12 BHCS. There is room to pull the four belt ends through and trim them at the front face of the DAB.

Stealthburner Version:

This version of DAB is a drop-in replacement for the Stealthburner x-frame pieces. It uses slightly different hardware than the official Stealthburner assembly, as shown in the picture below.

Stealthburner on a Switchwire:

This version of DAB fits a Stealthburner onto a Switchwire. It is printed in two parts and assembled with three M2x10 self tapping screws.
