LGX with mosquito for single rail MK3

This is a work in progress.  I will be testing this soon, but thought I'd upload it anyways.  There is an LGX filament sensor that works with the MK3, so you can use that.  I've had terrible luck with the reliability of the prusa filament sensor so I am designing my own simple switch (that's why there's spots for heat set inserts in the carriage file).

This will only fit the single rail x-axis, all parts (except tensioner if you are already using the original design) are needed as they will replace the original (and they're stronger anyways).  Countersunk M3 screws will be used to secure the base to the carriage.  High quality M3 heat set inserts are required for this model.  

I'll add more to this as I make this and test it.

Step 1: install M3 heat set inserts into all applicable parts.

Step 2: Install extruder carriage onto linear rail carriage using 4x m3x4 countersunk screws (this may vary depending on your linear rail carriage, I was also able to use 4x m3x6 panhead screws)

Step 3: Install back cap using 3x m3x6 panhead screws that go into the extruder carriage.  use 1x m3x12 panhead screw from extruder carriage into back cap (must be done before hotend is installed)

Step 4: Install M3 square nut into Base for the PINDA probe.  Install Base onto extruder carriage using 2x m3x10 on the top two holes using 2x m3x6 countersunk screws on the bottom (panhead screws may also be used, just take care with the top screws to make sure they're in as far as possible so the extruder is still able to be installed later, this may have to be modified depending on your particular clearances)

Step 5: Use 2x M2.5x6 socket cap screws to install the Mosquito hotend into the Base.  (The thermistor and heater cartridge should be pre-installed)

Step 6: Install Cover using 2x M3x16mm socket cap (or panhead) screws for the top holes, use 1x M3x25 socket cap (or panhead) for the bottom hole.

Step 7: Cut a piece of PTFE tubing to approximately 15.5-16mm.  Use a countersink bit to flare one end.  Insert the piece of PTFE tubing into the LGX extruder with the flared end going into it.

Step 8: Install the LGX extruder into the base using 4x M3x6 panhead screws.

Step 9: Install Fan duct and fan support, each using an M3x8 socket cap screw.

Step 10: install Cable Holder and route wires!

don't forget to change your steps per mm to 400, you can either use pronterface or similar or create a gcode that says:

M92 E400 

M500

Things may be changed in the future, some walls are a bit thin for the heat set inserts so it bulges (I just filed away the spots that bulged).

Edit 08Oct2023: Updated the back cap and carriage for zip ties so the wires can be routed on the side.  This should allow the carriage enough clearance for full Z motion to the top.  I haven't tested it yet though.  I also enlarged the hole for fan support heat set insert on the front cover as well.  The updated .step file assembly has also been uploaded.
