I have been working to upgrade my Workbee CNC to the Queenbee Pro CNC with the Bulkman3D kit. I noticed that the kit does not have endstop mounts, so after some measurements and a little time in Fusion360, I came up with some simple mounts for the OpenBuilds Endstops (https://openbuildspartstore.com/xtension-limit-switch-kit/) which include noise filters which really helped when I was trying to locate the source of some noise in my electrical system.
