This page is for those customers, that want to drill themselves the hole, that was missing from the gantry back plate on first production batch.
To mark the hole location, place the gantry front plate on top of the gantry back plate, like this:
Align the holes marked with green arrow. You’ll notice, that the hole marked with red arrow is missing, although in the CAD image, it is showing. Mark the location. Using a bench drill, drill a 5mm hole to the marked location.
Once more, my apologies for the inconvenience!
