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
Endstops
X & Y
- ??
Z
- ??
Software
Workflow
- Lists of software tools
Generating G-Code
- F-Engrave - DXF to GCode, single pass only
- gcodetools for Inkscape (not tested yet)
- dxf2gcode (not tested yet)
- image2gcode online, not tested yet
- PyCAM (not tested)
- http://simplegcoder.com/ (not tested)
- https://sites.google.com/site/heekscad/home/Details (not tested)
ToDos
- Put portal together, replace belt
- Test / identifiy endstops
- Build portal frame
- Evaluate Controller Software
- Find matching controller Hardware (like this or that.)
- Try Z axis brake
Sub-projects
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 (maybe that)
Software & Controller
- What will tell the drivers what to do? PC/parallel port, Mikrokontroller, old CNC hardware, ...
- Hardware? What do we need?
