Cyclone PCB factory V2

This project aims at equipping PTL with a PCB mill for rapid in-house electronics prototyping. The particular goal is to establish a well-maintained, in-house PCB production workflow. The final goal is to be able to complete simple projects (schematic → tested board) within an evening and have a decent throughput (“a PCB a week”).

The mill to be built is a Cyclone, version 2 (see links below). As of 8/11/2014, version 2 of the Cyclone has not yet been released, but it seems to be in a “PTL-complient-enough” shape to give it a try!

For a list of fabricated PCBs look at here PCB creation!

  • Assemble machine
  • Test
  • Document built and tweaks

Liste de fournitures

All parts are based on version c0c7732 (Hardware/CYCLONE_2) of the official repository. Not mentioning screws and other small stuff.

3D prints

Sorted by importance.

Electronics

Description Model Qunatity Supplier Comment/Status Picture

Stepper Motor Driver StepStick A4988 3 reprap.me arrived (x4)
Driver heat sink for A4988 3 reprap.me arrived (x8), but drivers came already with heatsinks
Power supply TODO 1 TODO 12V 7A (2A per motor + 1A for electronics)

Alternative electronics

This comprises newer stepper drivers (in case we need higher currents) and a RAMPS. The latter is also used for the 40W Laser Cutter and goes in direction of unifying PTL CNC controls, but might require some work for height-probing.
