Part 5) Behemoth X & Z axis assembly

Part 5) X axis and Z axis assembly as pictured below started bolting up the bridge pillars, did my best to get close to perfect but being profiles these can be adjusted easily after when everything is all together.         The bridge came together easily, though i plan to machine custom plates for the c-beam to bolt to 80160 profile. I’m sure behemoth will make its own upgrades when complete. 🙂   Read more…

Part 4) Hiwin Rails HGW15 cbeam Y-axis leadshine hybrid Nema 23

To Start off the y axis we designed a nema 23 mount and 3d printed it solid. This is only a trail to see how it performs but for this size motor i believe it will be fine. Decided to try a new type of stepper motor the leadshine hybrid Nema 23 are integrated closed loop hybrid steppers. Before assembling everything I couldn’t resist doing a quick frame mocked up and I must say it’s Read more…

Part 3) Hiwin linear rail mounted onto openbuilds cbeam X axis

Hiwin Linear rail mounted onto openbuilds cbeam X-Axis The install of the Hiwin Linear rails onto openbuilds cbeam wasn’t plug and play, it required some grinding of the v-slot by 2mm so t-nuts could slide onto the profile. I took my time doing this because the grinder could easily destroy the profile. overall it came out okay besides from a few scratches here and there. Below image shows 1mm sanded from the outer edge of Read more…

Part 2 C-beam CNC Rigidity Epoxy filled Profiles

This part of the build was looking for the cheapest way to boost the frames rigidity and dampening effects so it can handle machining metals. I decided to use 3 lengths of 12mm reo rod that was purchased cheaply from the local hardware store which i glued in with epoxy resin. The reo rod diameter was slightly too large for the c-beam profiles so I used an angle grinder with sanding wheel and shaved off Read more…

Part 1 Behemoth c-beam cnc Design phase

Part 1) The Design process behind the Behemoth C-Beam desktop size Bridge milling machine Openbuilds c-beam platform by Mark Carew was the inspiration behind my design so thanks guys and hopefully I can contribute back to the community with my build ideas. I finally decided to build my behemoth c-beam mid-2017, originally was going to build the Sphinx style moving gantry router 750×500 but during my Cad design process & planning I started to realise Read more…
