Description
3040-MGN 3-Axis CNC Router Mechanical Kit
For sale a new “MGN” line of CNC desktop routers, suitable for engraving/milling in such materials as: wood, plastics, epoxy resin sheets, soft metals. It is a variation of a 3040 CNC router which contains 4x Nema 23 motors( 2 x motors for Y-axis). Two motors for Y-axis provide better, more stable and stronger movement.
This build is based on decent MGN12H bearings and MGN12 hardened steel rails and 2080 extrusion profiles. It provides much more stability and accuracy than builds based on Openbuilds Delrin wheels or Chinese construction CNC routers based on SCS or SBR ball bearings. The Z-Axis module contains high quality LM16LUU linear bushings. Our 3040-MGN CNC Router Mechanical Kit is equiped with hardened steel MGN12 rails, which significantly increase the accuracy of cutting in engraved or milling materials.
We sell pre-assembled mechanical parts machines with stepper motors & drag chains. However some assembly is required. Gantry side bridge arms and front/back plates of the router are made of hard bakelite which has tensile strength comparable to aluminium gantry arms of same thickness. It is also much lighter than aluminium. Thanks to that, our machine kit weighs just about 12kg. It is also easy to assemble and disassemble and will fit easily on a mid-size desk.
Also, we made a great effort to design a machine where rails and transmission screws will be as much as possible separated from the working area, so dust and chips will not gather on rail and screws. It will increase the life of moving components( bearing slide blocks, anti backlash nuts). 3040-MGN is a perfect tool to start your CNC milling journey.
PLEASE NOTE!!!
Price do not include controller/driver board or 65mm palm router. Suitable GRBL controller box and a 65mm palm router can be found in our store.
It is the buyer’s responsibility to check and tighten all screws, especially MGN rail M3 bolts, also machinery needs to be aligned and angles must be set with precise probing tools, to achieve a best milling accuracy. Do this, unscrew gantry bolts a little and set 90 degree angles, then tighten bolts back .
OPTIONAL ITEMS(can be found in our store):
65mm palm router
This palm router will fit in the supplied 65mm spindle mount provided. Power for the router is sufficient to successfully mill in materials like: hardwood, acrylic, epoxy, hard plastics Compatible with Makita/Katsu palm router.
