MGN12 X axis
|
|
============
|
|
|
|
**Note:** Voron Trident officially uses a slightly improved version of this
|
|
mod. It is suggested to use the X axis parts from Trident instead.

|

This replaces the dual MGN9H rails on the V2.4 X axis with a single MGN12H
|
|
rail. The belt is directly clamped to the MGN12 block by the carriage.
|
|
|
|
The stock PL-08N probe _might_ be too long to fit. Recommended alternatives
|
|
are listed below.
|
|
|
|
As an option, the `x_carriage_frame_right_endstop.stl` allows mounting
|
|
the X endstop switch on the carriage, which is useful on an umbilical cable
|
|
setup.

Thanks to joshmurrah, hartk, and everyone else who helped out in one way or
|
|
another.

Required hardware
|
|
-----------------
|
|
|
|
In addition to things you can reuse from the stock build, these items are
|
|
required:
|
|
- 1x MGN12 linear rail with MGN12H carriage (same length as the original MGN9
|
|
rails)
|
|
- 1x M3x40 SHCS
|
|
- 4x M3x8 __BHCS__ (or 2x BHCS and 2x SHCS)
|
|
|
|
Recommended probes:
|
|
- Omron TL-Q5MC2 (use M3x25 or M3x30 screws)
|
|
- Panasonic GL-18HB/18HLB (use M3x25 or M3x30 screws)
|
|
- Panasonic GX-H15B/HL15B (use the 9mm probe bracket, and M3x16 or M3x20 screws)
|
|
|
|
Instructions
|
|
------------
|
|
|
|
Assembly is similar to stock V2.4, see the assembly images below.
|
|
|
|
The belts are clamped between the carriage and the MGN12H block. This
|
|
procedure worked for me:
|
|
1. Loosely fasten the carriage to the MGN12H block using the M3x8 screws.
|
|
2. Push the belts in on the left side, until they are just visible in the
|
|
middle. Tighten the screws on the left side a little bit, to secure the
|
|
belt ends.
|
|
3. Push the belts in on the right side as far as you can, and pull them out
|
|
through the middle.
|
|
4. Tighten all screws, while making sure that all belts are firmly held in the
|
|
clamp teeth.
|
|
5. You may wrap the extra length of belt around the probe cable, as in the
|
|
photo below.
|
|
|
|
Please check the Z endstop position after assembly as it may have changed
|
|
slightly.
