MPCNC z axis drag chain mount

thingiverse

This mount secures the MPCNC z axis stepper, bypassing attachment to the top of the Z axis assembly. Mounting the drag chain atop the z axis rails exerts considerable leverage on the z axis, potentially leading to instability. In contrast, this setup attaches directly to the XY part, which is more resilient under stress. The mount requires drilling two holes in the XY part and securing with through-bolts. Assembling the mount can be a bit tricky, but placing nuts within reach using a dowel and superglue facilitates completion. Alternatively, using properly sized wood screws achieves the same level of stability without the need for adhesives. Additionally, the setup necessitates drilling two holes to secure the drag chain in place, depending on the chosen size of the drag chain.

A 60% infill provides more than sufficient strength, making it a reliable solution.
