MPCNC - Original corner block with limit switches Remix for US & IE Version

thingiverse

I updated Rev9. I had some interference fit problems with the original, so I changed a few things to fix that and also made a version to use Mechanical switches instead of circuit boards. The y-axis mechanical version may be a tight fit getting the wire on there, but it looks like it should work. I have also uploaded a U.S. and IE version of each design. There is an OpenSCAD file for the 2 designs that you can also change to your liking. One downside to this design is that you can only print it in the upright position. I copied the geometry of this design into OpenSCAD, so it should work for US or IE versions. You just need to change the variable: EMT_OD = 23.6; // For US version EMT_OD = 25; // For IE version For the U.S Version that uses circuit board switches use the STL files: Corner_Block_LockRemix_WithLimitSwitchBoard_A_Rev9_repaired.stl (for Minimum limit switch) Corner_Block_LockRemix_WithLimitSwitchBoard_B_Rev9_repaired.stl (for Maximum limit switch) For the U.S Version that uses mechanical switches use the STL files: Corner_Block_LockRemix_WithMechLimitSwitch_A_Rev9_repaired.stl (for Minimum limit switch) Corner_Block_LockRemix_WithMechLimitSwitch_B_Rev9_repaired.stl (for Maximum limit switch) The International versions have a prefix of IE for the STL files. For reference, I used the Limit Switch: https://www.thingiverse.com/thing:1039934 I included STL files for the 2 opposite corners like the original version. You can also create your own modified version from editing the included OpenSCAD file. There are 2 STL files that just used for reference in the OpenSCAD file, the limit switch circuit board and Corner Block. I am using 4 M2x10mm with a locknut to connect the Limit switch boards. M2.5 would work better, but I did not have those in a 10mm length. I used M2.5x16mm bolts for the mechanical switches, but 14mm length will probably also work. After installing this, I realized this idea will only work for the Min. X and Y switches. The center section is too far away when it hits the limit at the maximum.
