Optical endstops for my BLV mgn Cube.
The X-endstop will work with the original design. I've included all the modified parts for either a bowden setup or a BMG direct drive setup. I've also included my own modifications for the BMG direct drive which contains support for better cable management and a more open "block shield" so cables wont get pinched.
A slight change on the XY-joiners, I've replaced the middle M3x45 screw with a M4x45 screw and nut instead. This was because I had some difficulty sourcing longer M3 screws than 35mm, but M4 was readily available. I've included the
.step files if you don't want/need to use M4 screws so that you can easily revert back to M3.
I used M3 threaded inserts for mounting the X flag. But if you don't have that laying around you can easily change the diameter of the holes to 2.8-3.0mm.
Do note that the Y-endstop will currently NOT be compatible with Ben's original design! It all comes down to the differences on my machine. His design uses 36.751mm between the top and middle aluminum extrusion, while mine uses 41.00mm. This creates a difference of 4.251mm that needs to be adjusted somewhere, either on the optical endstop mount itself, or the flag location or both.
Unfortunately I don't have the time to fix this right now, but I've included the
.step files for easy(ish) modification. If you do find a solution to this, it would be greatly appreciated if you share and tell me, then I can link to your solution :)
- Y-axis optical mount compatible with the original BLV mgn Cube
- Add two dowel pins to the BMG motor mount for better stability. It's currently mounted with a single M3 screw and nut.
2019-06-03: Added a wide version of the Block shield, enables easier installation of LED lights in front of the hot end.
