Description
We currently have a under construction C BEAM based CNC Mill. The mill took its first cut on 20/02/2016.
The CNC Mill is based on the C BEAM profile from open builds, it is currently a X/Y table type "C BEAM MACHINE" thats 400x400x120mm but we have all the parts to make it a 1000x750mm gantry style ASAP.

Design
The first machine is a 'out of the box' C Beam Machine kit [2]. This is a X/Y table machine based on the C Beam aluminum profile which offers better stability and accuracy than OX type v slot or shapeoko.
This kit will be used to make the plates for its own upgrades into our specific 1000mm x 750mm gantry style machine with dual X drive based on this design. [3]
Parts Status
We have purchased the majority of parts from Colin at robocutters.co.uk[4], he offered a wealth of advice, a great discount and is genuinely interested in supporting Hackspaces.
- A C Beam machine kit
- 3 NEMA 23 Motors
- 1 1000mm linear actuator kit
- 1 750mm linear actuator kit
- 4 750mm 60 aluminium profiles
- 16 wheel kits
From China we ordered as a kit:
- 800W 60mm mount water cooled spindle
- 1.5kW VFD
- 12 VPump
- Various collets
From other sources:
- 6 C.P type limit switches (swwils)
- Radiator (swwils)
- 4 Core spindle cable (swwils)
- RUMBA Board + Drivers (Martyn)
Build
- First cut occurred
- Safety and software phase started
