I was having issues with my toolhead board colliding with my Z chain when homing Y Axis on my Micron R1 180. Custom Homing Overrides helped but didn't completely solve the issue. I wanted to find a solution that didn't require me to dissemble my gantry or re route wires while keeping the existing stock Y limit switch. I came up with a solution to install a pod on the X axis joint to push the Y axis end-stop switch about 8mm sooner. This solution works for me with Zero loss in bed area or collisions with my toolhead carriage, YOUR SITUATION MAY BE DIFFERENT, MAKE SURE YOU TEST BEFORE HOMING.
My current setup:
Honey Badger CNC Printers for ants carriage.
Dragon Burner
EBB36 Toolhead Board
G2SA extruder
I had to move my bed a little forward, and change my printer.cfg to reflect the change in bed and the loss of travel in my instance 8mm. I’m also using my homing override macro to position the tool head in the center of X axis before I home the Y axis
here is a good article on how to configure your printer dimensions and homing
BOM:
2X M3X15 BHCS
You’ll need 2- M3x15 BHCS to replace the M3X8 BHCS that secure the top of the X axis joint to the extrusion.
.STEP file is included so you can make any changes you need.
This design uses a dovetail and locking geometry. It's keyed so you can't install backwards, you'll need to push the pieces against a solid object, like a table. You could add a drop of CA glue to ensure permanent fit, depending on printer tolerances it doesn't seem necessary.
