VoronUsers/printer_mods/hartk1213/Voron2.4_Pins_Mod

This mod is for the V2, it involves printing new AB drive frames, new XY Joints, new Front Tensioners, and new Z idlers

The pins have replaced m5 screws, at any location where the screw acts like a shaft, holding bearings, pulleys or idlers. This allows for smoother rotation and stops the possibility of motion parts being caught in threads. This work was done by everyone, thanks to ABS plastic and voron printers for the fast iteration, @doomweasel? they fall out yet?

To complete this mod the following files will need to be reprinted

A and B drive units

• a_drive_frame_lower_pinned.stl
• a_drive_frame_upper_pinned.stl
• b_drive_frame_lower_pinned.stl
• b_drive_frame_upper_pinned.stl

Front Idlers

• [a]_a_tensioner_pinned.stl
• [a]_b_tensioner_pinned.stl

XY Joints

NOTE: There are now 2 versions of these files , 1 set for Stock 2.4 and 1 set for Arkeets MGN12

• xy_joint_left_upper_pinned.stl
• xy_joint_left_lower_pinned.stl
• xy_joint_right_upper_pinned.stl
• xy_joint_right_lower_pinned.stl

or

• MGN12_xy_joint_left_upper_pinned.stl
• MGN12_xy_joint_left_lower_pinned.stl
• MGN12_xy_joint_right_upper_pinned.stl
• MGN12_xy_joint_right_lower_pinned.stl

Z Idlers either one of these based on if you are using 6mm or 9mm belt

• [a]_z_tensioner_x4_6mm_pinned.stl
• [a]_z_tensioner_x4_9mm_pinned.stl

here is what the XY Joint will look like

There is a new file for the A Drive to go along with Arkeets MGN12 mod that has the X endstop on the toolhead

the files for the endstop relocation mod are here Voron2.4_Y_Endstop_Relocation

the following 5mm Pin hardware is what is needed as well

BOM

[A-B] 
threaded @  30mm (x2)
smooth   @  28mm (x2)

[X-Y Joints]
smooth   @  40mm (x4)

[X-Y Idlers]
smooth   @  43mm (x2)

[Z Idlers]
smooth   @  28mm (x4)

these can be purchased from here

Misumi Part Numbers

Part NO.	Qty
SFRT5-30-M3	2
SFR5-43	2
SFR5-40	4
SFR5-28	6

NOTE: 2 smooth pins can be substituted for the threaded pins, the reason the threaded pins are there is for easy removal without the need to remove the stepper. but if you dont plan on removing the pins without removing the stepper than smooth pins would work just fine for you in this situation.
