Make some tools for it.
Want to know how flat (or not) your material is? use a dial gauge mount and jog the head around. Shim or surface the platform as needed.
It only comes with one cutting surface / platform. This a bit of a limitation because each material has different needs.
Cutting / Drilling PCBs works best with "soft" material, backed with a stiff surface. Laser cut and mill all the base plates needed: MDX-15 Base Plate, MDX-20 Base Plate
Clean up the wiring. Mounting the power supply on the back, or hide them inside the side covers make for less handling / cleaning issues. The side panel on the on the left is hollow and comes off with two screws. One small notch was all it needed.
Make a blower / collection bin. Removing the cutting makes for better and trouble free milling. The design are here: MDX-15 and MDX-20 . This removes cuttings from the work surface, and collects them in the back by both blowing from the front and pulling air from the back.
The dust case has a drop so cuttings go down and air goes up. The blower needs a minimal filter.
It blows... It sucks... yeah...yeah...
