JGAurora A5-A5S - Linear rail X - MGN12H - FINISHED
Here is the publishing of the MGN12H rail for the X axis V1.0:
https://www.thingiverse.com/thing:4352006
This modification is for installing a linear guide on the X axis.
3mf print files and STEP files are included to be able to modify the parts and customize them.
There are two versions of the carriage, one without BL-Touch and one with BL-Touch. The accompanying guide shows the distances to position in Marlin:
X: -19mm
Y: -46mm
The first and important step is to replace the Z limit seat so you can adjust the height freely.
It includes a list of materials, some of which are reusable from the X-axis such as t8_trapezoidal_nuts and screws and X-axis switch screws.
Installation Guide is included.

Comments
The improvements I've noticed are two basically:
The first and obvious is the improvement in extrusion control thanks to the direct system. I'm using retractions between 0.6 and 0.8mm.
The second is to have a belt tensioner. My A5 was one of the first and it was a pain to tighten the strap and the vibrations and artifacts it created.
The worst thing I think would be the loss of impression volume space staying at 270x285x260mm. In my case I do not make such large pieces but I recognize that it is a loss that must be valued.
The next Project is to improve the Y axis.
Howdy, Stranger!
