I wanted to turn my XYZ Davinci 1.0 into dual extruder with auto bed leveling.
I replaced my controller with MKS Gen V1.4, got Chimera clone, extra motor and
...Show more bltouch.
Now the trick was to make sure I don't lose much bed space with this upgrade.
With this XCarriage I have full 200x200 space and about 195mm height clearance.
you will need 3 linear bearings to attach this to xcarriage rods. once linear bearings are on the rods you can take out xcarriage for maintenance without taking the whole printer apart.
I did PLA part cooling fan, not the best design but gets the job done right now.
Will change that tiny fan hole to a more elegant design later on and add LED light bar to the print head as well.
