K40 eBay Chinese CO2 Laser Cutter – Replacing the Controller with Arduino and GRBL Part 1!

Please visit www.DIY3DTech.com for more information on this and many other projects! As in this episode we will be kicking off a series to replace the standard proprietary controller found the common 40 watt eBay K40 CO2 laser models with an Arduino and GRBL running GRBL. This will do away with the flaky operation of Corel Laser & Laser Draw as well as the need for that crazy little USB stick! Instead at the end we will be able to operate this machine properly with GCode and like tools!

CNC Tips and Tricks – Cutting Extruded Polystyrene Sheets

So in this episode we are going to look at machining sheets of extruded polystyrene sheets we bought a  couple years back.  This was very cheap verses that of acrylic, however machining is a bit harder as the plastic wants to melt rather than cut.  So what we did was:

1. Use a 1/8″ 2 flute end mill (amzn.to/1LMWEJy)

2. Kicked the speed up to 100 Inches per minute

3. Slowed the spindle down to only 1/3 speed using a speed controller(amzn.to/1GUViXB)

 

A. Polystyrene

 is a synthetic aromatic polymer made from the monomer styrene. Polystyrene can be solid or foamed. General purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year. Polystyrene can be naturally transparent, but can be colored with colorants.

As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion, and also for molding and vacuum forming, since it can be cast into molds with fine detail.

B. Polystyrene features

  •  Excellent light transmittance.
  •  High mechanical strength.
  •  Weather proof
  •  Non-toxic and chemical resistant.
  •  Easily be processed

C. Polystyrene applications

  •  Advertisement: blow molding board, CNC engraving materials, Laser engraving materials, sign board,  light box,  window, logo and mark, etc.
  •  Furniture: office furniture, cabinet, window, etc.
  •  Finishing Material: decorative sheets, storage racks, room segments, etc.

2 Watt Laser Cutter and Engraver Project Part 8 – First Test Cuts of Machine!

So we connected the laser and sorted the PWM pin for TYL (the -Z pin) and got the whole thing to work!  It was exciting to see the whole thing work the first go around as we built it all the way up from a 2 watt laser diode to the maker rail motions running GRBL!

InkScape Workflows to GCode – Cutting a Logo with a Laser!

In this episode we will use the free InkScape application to convert a raster image (PNG in this case) into a vector and than to GCode to cut on our laser cutter.  Worth note is this will also work with other raster image formats such as JPG, GIF and others.  Also this is a workflow video so we will talk about how we several programs to create a “workflow” which gets us to our end product.  In addition, while this will cut on the laser cutter, we could also run the same code and mill this on the CNC machine as well.

2 Watt Laser Cutter and Engraver Project Part 6 – Setting up the CNC Proto-Sheild

In this episode we will look at configuring the CNC Proto-Shield for the Ardunio and GRBL for the laser cutter.  For more information on the CNC Proto-Shield click this link, also for the configuration page click here.  This has turned out to be a great little board for the money and highly recommend it for any type of CNC project which your working on!

28BYJ-48 Unipolar to Bipolar Conversion Project – Part 2

In this video we will complete the conversion of the 28BYJ-48 stepper motor from unipolar to bipolar format and drive it with an Ardunio Motor shield (Click here for shield info: http://amzn.to/1jhdlCj).  Also if your looking for the 28BYJ-48 motors, you can just click here to get a package of 5 or simply find out more these little gem of a motor.  Also for the coil pairings, in my case it was: Blue & Yellow and Orange & Pink.

Below is the sample code to run the modifed 28BYJ-48 stepper motor in bipolar mode:

Using a Laser to Recycle a Cereal Box Into a Stencil!

In this episode we will use our CNC mounted 2 Watt Laser Diode cutter to recycle a stencil out of an old cereal box! I have this is a great tool for recycle and reuse of things that would normally end up in the trash.  How use care when cutting due to both fumes (which could be toxic) and reflections from shinny surfaces so use care when cutting something new having proper ventilation as wearing the correct safety glasses for your laser!
