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
- 3x JMC 3M860
Power supplies
- 3x 70V 400W from China
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
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
- needs to be powerful (Aluminium) and precise (pcbs)
- Find matching Spindle with driver and cooling
- Bought this: that
Software & Controller
- What will tell the drivers what to do? PC/parallel port, Mikrokontroller, old CNC hardware, ...
- Hardware? What do we need?
- Main page for this: CNC_router_software_eval
