- 4.
- 7. CNC Machine •3D Printer • Milling Machine • PCB • Wood
- 8. Why choose PCBMiller • too many 3D printerS in makerfaire • a Milling machine for wood is too hard and too expensive to build • Can help on building feature projects
- 9. Aid future Projects • make Smaller Boards • enable the use of SMD components • make a lot of duplicates if needed
- 10. Handwire vs PCB • Dirty • Hard to duplicate • Cheap • Fast
- 11. Handwire vs PCB • Clean and tidy • Easy to duplicate • Expensive
- 12. Ways to makePCBs
- 13. Etching • Slow • Dirty and toxic • expensive per board if home-brew • expensive in small qty if manufactured Milling • Fast • cheap in small qty • higher resolution (if trimed)
- 14.
- 15. • Working area20 x 20 (cm) • Machine size 55 x 40 (cm) • Use CNC miller Wood parts as Machine frame • A moving Table Design • Brushed DC motor Miller <ER11> • TI motor Driving solutions • All Standard Mechanical part
- 17. Controller MCU CortexM4 FPGA • Easy to code • GUI • Fast • Have useable code • Can turn motor at absolute same timing • Use SoC can do a lots of things
- 18. G-Code • 移動 G01 X00 Y100 Z20 F20 • 畫圓 G03 X2 Y0 I0 J-2.0 • Query Statues M114 • Motor Enables M17、M18 • A lot more, from G00 to G99, M0 to M99
- 19. Stepping Motor •Moving by steps • Absolute positioning • TI DRV8832 • Dir, Step control • Micro stepping
- 20. Current Code •CAD file -> G-code • pycam • Decode G-code into opcodes • self written python code on PC • opcodes -> Real Physical actions • ARM MCU
- 21. Plan • Portprevious work on FreeRTOS • Decode G-code on ARM Core • floating point is a obstacle • Implement more G-codes as more as possible
- 22. Obstacles we arefacing
- 23. See You atMakerfaire
