I’m starting to work on the z-axis assembly and I have a question recording the holes that need to be drilled into the z-axis rails. The instructions state a 5mm to 8mm hole diameter for the nut trap/tool mount bolts. These holes a larger than the bolts supplied in the bundle kit. I’m assuming that this is to allow for alignment adjustments when everything is put together. I going to opt for a 7/32(5.55mm) bit for drilling the holes. Should I go larger or will this do. Note I’m using a drill press.
