Machine Class – Full Size Heavy Duty Maker

Maximus-HD is a new class of heavy duty Maker Routers, we call it Max for short. It’s a full size Maker grade CNC platform. Its intended for large scale DIY Creative projects. It speedily and easily cuts soft materials such as timber, plywood, plastic, MDF and foam. It will also take on aluminium happily. Its bed accepts a full sheet of metric or imperial plywood with 150mm margin for clamping and fixtures.

For hard materials choose the 10:1 gearbox option. If its foam or very soft materials you need in a hurry choose the 5:1 gearbox option. The stand and base is up to the Maker. The Maker can build it in half sheet size or make it very long. Adjust the bench and rail lengths to suit your own application.


Maximus’ structural elements are made from laser cut and precision folded S30400 stainless steel sheet and plate. Parts can be polished for an extra cost, see the price list. The Maker can build a metal or timber bench depending on their resources and work requirements. Plans for a timber stand and bench are in the price list as well.

  • Z Drive is a 1610 ball screw with Nema23 4Nm motor and electric brake
  • The X&Y Drives use a heavy duty 25mm wide precision ATL steel wire belt. ATL belts are optimised for positional applications
  • The Maker can select the grade and price of the standard parts. From economy bearings to high performance it’s up to you and your budget
  • All motors are Nema 23 high torque and use precision gearboxes with stiff 14mm diameter output shafts
  • The large gantry is exceptionally stiff and all structures have been structurally analysed and optimised using finite element analysis
  • Maximus is a fourth generation machine based on Tetra Motions in-depth testing and ongoing CNC machine development programme
  • Why stainless steel? Because its cheaper, go figure! But if you want it to be orange or bright green then you can do this or we can, just ask.

Shopping List

Tetra-Motion supplies mechanical and structural components for CNC machines. We stock hard to get parts and we stock the parts we manufacture ourselves. All other standard parts can be supplied by bearing outlets, electronic stores and your local hardware. Tetra Motion provides a part specification and shopping list with expected costs for standard parts so you can easily cost and source the parts for your machine wherever you are.

Tetra Motion does not sell machine “kits” we sell individual parts. We have found that every CNC machine builder is different and requires different parts or is at a different stage in their build. By selling individual parts we help solve your build issues faster. The Maker gets what they need in a no fuss manner. Just get our parts list and check the items you want. Or email us describing what you want and we will put together a suggested Bill of Materials and quote for you.

Bespoke Parts

Because Tetra Motion is regularly ordering various parts we are very happy to quote on the supply of bespoke machine parts from one off to production OEM quantities. Just snail mail that napkin sketch to us and we will digitise it quick sticks!
