I like the stability and functionallity of the Prusa MK3, and combined the Bondtech BMG extruder together with Kozamakers X-carriage for the Tronxy X5S with the smart belt tentioning mounts.
The Cable chain is about 30mm higher then the original, to go free of the belts.
The carriage is stabil with 4 wheels that is really tight, You might want to drill/clear the holes in the back to take some load of the wheels, and easier assemble. But make the holes in the front to stay narrow.
- Start with mounting the 4 long screws for the wheels to the front carriage. You might want to glue them, since you are not able to reach them when putting the carriage on the printer.
- Mount the Prusa extruder parts together with the Bondtech BMG / E3D hotend. And remember to press in the 3 m3-nuts in place (use a m3 screw and tighten them in place).
Replace the 3 BMG-screws with 3 pcs M3x40.
Check that the BMG and stepper motor is working, and all parts go free.
- Mount the extruder parts to the X-carriage with 3 m3 screws from the back.
- Mount the X-carriage and v-slot wheels on the printer.
Remember to set e-steps to 415 for the BMG (Marlin) or 830 for 1/32 microstepping (Smoothieware). If you can´t change it in firmware, use start code: M92 E415 in your slicer.
Print the parts with high infill. (>80%) Pet-G or PLA-pro/HT-pla prefered.
Print with support.
