MGN12 X axis
|
|
============
|
|
|
|
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 is not supported as it is too long. Use one of the
|
|
alternatives listed below.

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.
