CNC V9 Oozenest beltless 3 motors
Description
#I'm moving to Cults3D.com **files available at https://cults3d.com/en/3d-model/tool/cnc-v9-oozenest-beltless-3-motors** **Finally I did it, see video below** [Functional test](https://youtu.be/WWbq8JD_XoE), slow speed because it's a stone carving file... After completed my [V7 version](https://www.thingiverse.com/thing:4462424) and began to use it I discovered that belts are prone to stretch, slip and so on at a minimal error of mine (who doesn't do?) even using GT2 belts with iron inside; furthermore I cordially hate belts, since my first printer I always implemented the less infamous T8 lead screws. That said, this is my interpretation of Ooznest OX CNC in T8 form. Changes made: - only three Nema23 now needed - Y axis hidden below thw workplane - moved the two 2060 X axis carriage profiles 20mm to front to align them to X motor - boxed Y carriages, to better protect wheels from dust, chippings and whatever else - use of well known Arduino Uno and CNC shield, cheap and affordable - an SSR relay DC-DC, valid option for direct or PWM drive the spindle motor - X/Y/Z magnetic endstops, not strictly necessary but... - an safety switch that can act as main power switch too - chinese 200W spindle motor 12V 5000RPM / 24V 10000RPM. I bought it because I don't need a more robust one, but you can find a bunch of spindle motors at Aliexpress at reasonable prices. - cooling covers for Nema23, you'll need them for sure - lowered work plane by 20mm, gained in favour of Z axis - changed location of electronic items to back and added an 2040 profile to protect them - vacuum dust collecting system with Neato motor (that of Roomba) - alternative cyclone dust separator, tnx to [mgx](https://www.thingiverse.com/thing:124551) - optical Z finder, see [here](https://www.thingiverse.com/thing:4571246) - 8"-10" tablet support, orientable on 2 axis - an Automatic Tol Changer, see [here](https://www.thingiverse.com/thing:4584693) and [here](https://youtu.be/PQpgL7FScZQ) Working limits are about X=300mm Y=500mm Z=30mm I provided a laser support too for who loves engraving.
