CNC Mill

Release status: experimental [box doku]

Description
Author(s)  Tarwin
Last Version  v0.1

We want to use the big-ass CNC portal Thomas rescued from the trash to build a CNC router.

Goals

  • Mill Aluminium!
  • route PCBs
  • be open for extensions, easy tool change

Hardware

Motor System

X & Y Motors

Z Motor

Motor controllers

Power supplies

Endstops

X & Y

  • ??
  • Seems to be an Solid-state Auto Switch, not just a Reed sensor, maybe same pinout as the SMC

Z

  • SMC D-F9H (datasheet) (Solid-state Auto Switch, works like a PNP transistor)
  • Omron EE-SX870p Photomicrosensor (datasheet)

Software

CNC_router_software_eval


Sub-projects

Fix up portal

  • The portal needs to put together and fixed up
    • Put portal together, replace belt
    • identifiy / Test endstops
    • Build portal frame
    • Try Z axis brake


Frame and table

  • The X Axis is raised, the linear bearing runs far above the tool head. This implies a high center of gravity.
  • Frame needs to be very stable
  • Maybe use old routing table placed inside the frame to have a stable and level working surface
    • Build / reuse old routing table (should be movable by itself, maybe use old manual router)

Tool head

Software & Controller

  • What will tell the drivers what to do? PC/parallel port, Mikrokontroller, old CNC hardware, ...
  • Hardware? What do we need?
