The instructions that come with the BitSetter are not very complete when it comes to installing the splitter PCB.
From the installation guide:
“After your cable is routed to the Carbide Motion Controller, re-install the controller cover or enclosure. Make sure not to pinch or accidentally loosen any of the cables.”
In order to address this design flaw I made a small wooden enclosure for the BitSetter splitter PCB. It attaches to the carbide motion controller enclosure cover with double stick tape. The enclosure is MDF, the cover is 1/4” plywood and 6-32 x ½” round head bolts secure the top to the enclosure. A few pieces of packing foam keep everything in place.
The cable / connectors that come with the BitSetter easily feed through the rectangular opening on the rear of the carbide motion controller enclosure and are long enough to reach the wooden enclosure.
