This model introduces the VzBoT-Vz330 gantry to the Flying Bear Reborn 2. It enables the usage of the Vz-Printhead without changes.
\nThanks to the VzBoT team for the Vz330 (2WD) and the Vz-Printhead - https://github.com/VzBoT3D
\nThanks to the german 3D printing community of https://forum.drucktipps3d.de
\nThis chapter focuses on building the components for the Reborn 2. For further information on the remaining VzBot parts, components and assemblies, please check the public VzBoT-Vz330 Github repository for 2WD setup (Link).
\nFull assembly: Onshape Workspace Link (reduced snapshot, 2024-02-06)
\nThe parts were successfully printed with ASA on a Bambulab P1S (tested with Extrudr DuraPro ASA and Fillamentum ASA extrafill).

\nLessons learned
\nABS and ASA react extremely to temperature changes (warping). Therefore, print with an enclosed chamber. Do not open the chamber during printing, not even for a few seconds! Always wait until the printed parts have cooled down completely before opening the chamber (equals ambient temperature).
\nThe material list only includes the parts required to assemble the components described in chapter 2.3. It does not include the parts for the remaining Vz330 gantry or for the Vz-Printhead.

\nNEMA17 stepper motor / 5mm shaft
\nNote: The original X stepper motor has an extra-long shaft with a length of 31.5 mm, which is quite unusual.
\nThe design of the motor mount takes into account stepper motors with a minimum shaft length of 20 mm (e.g. LDO-42STH48-2504MAC). Please note that with a shaft length of 20 mm, the motor pulley is not completely covered.

\nThis chapter focuses on the installation of the pre-assembled components as described in chapter 2.3. Further information on the remaining VzBoT assembly steps can be found in the public VzBoT-Vz330 Github repository (Link).
\nX/Y axis specific
\nRemove all stock parts of the X/Y motion system including the motors, idlers, gantry, printhead etc.
\nZ axis specific
\nIt is assumed to use some kind of bed leveling probe with the Vz-Printhead. Due to that and the uplifted gantry, please remove all optical endstops and indicators on the z axis.
\nIf you still want to use these optical endstops then you have to design custom indicators which are aligned for the installed hotend (highly user specific).
\nSlightly loosen the screws on both linear rails for Y and move them by -15 mm to create some space for installing the Idler Mounts. Then retighten the screws of the linear rails.
\n\n\nAttention: Please use the Flying Bear Reborn 2 linear rail mounting helper (Link) to align the linear rails horizontally before retightening.
\n
Mount all pre-assembled components to the frame as shown in the following pictures.
\n\n\nFor the installation of the X beam, MGN9 rail, Vz Printhead etc. please check the Vz330 repository (Link) and the Youtube channel of Simon Vez (Link).

\nPictures
\nFor the belts installation please follow the VzBoT assembly guide.
\n\n\nCaution: Please put the belt clips as close as possible to the Vz-Printhead. Otherwise the belt-clips will be moved into the idlers of the Y gantry while homing.
\n
The belt tensioning mechanism is similar to that of the standard Reborn 2.
