Move to new house/office has been hard, but we are now ready to resume production. Most boxes are unpacked, equipment is calibrated and assembly has began.
There are many steps involved in producing a PiBurn.
- 3D printing plastic parts is currently done mostly on Prusa i3 MK2.5 printer. It produces a reliable, strong and nicely textured parts in PETG material. We have other 3D printers in our shop, but Prusa seems to be best for this job. And we are getting another one soon to handle the load. 3D printing takes a very long time (several days for just a handful of orders) but fortunately it doesn’t require much interaction.
- Acrylic Parts are Laser Cut from 1/4″ cast acrylic. We’ve made some extra parts before the move to fulfill orders while our Laser Cutter is being setup at new location.
- Wiring stepper motors takes a lot of effort, as each individual wire is soldered to the motor and the plug. Then wires are placed in wire loom and finally each motor is tested for correct operation and direction of rotation with Stepper Driver.
- Then aluminium extrusion rails are cut to length and threaded. We can produce PiBurns of custom lengths thanks to the modular design that uses 2040 extrusions. We’ve made rotaries from 16″ long to over 3 feet.
- Bigger parts assembled with tons of machine screws, washers and nuts. Axles inserted into wheels and bearings with hand press, motors installed and belts are tensioned.
- Clamp takes some fiddling as there are many small parts that need to be assembled just right and springs are also hand made.
- Whole PiBurn is test assembled and aligned.
- Finally we partially disassemble, clean and package components and pack everything for shipment to our customers!
