Laser cutter/etcher update 11/06/16

Lets see. What have I been up to?

  1. I began disassembling the $5 scanner from craigslist
  2. I got an old scanner from my brother that I will start taking apart soon
  3. I ordered necessary bits for the electricals from the interwebs
  4. I almost completely changed my design plan. (I will explain more below)
  5. I went to Home Depot to pick up the wood and screws and such
  6. I fixed my mother’s toilet, which admittedly has nothing to do with this
  7. I did some test cuts in vinyl (logic for this will also be written below)
  8. I also did some test etches on the University laser cutter just to get an idea about material logistics
  9. I received my diode in the mail (Happy dance because it was $40 less than I was anticipating)
  10. I managed not to physically injure myself, or anyone else for that matter, but I did tear my new shirt though so maybe that counts?
  11. I got a pretty good Rhino model set up and even did a little Keyshot rendering done.
  12. Went to Midland Plastics in search of acrylic. I didn’t find black like I had wanted, but I did find red and so I am going to see what I can do with it for this project. YAY RED!!!
  13. I got more bunnies transferred from pen drawings into Illustrator and Rhino
  14. I received 9 8″x8″ black shadow box frames in the mail to put the final pieces into
  15. I found my Arduino Uno. I knew it would come in handy in the future.
  16. I am setting up a time budgeting list so that I can stay on track and get this finished
  17. I tried to figure out when I will have time for a social life. So far I am failing on that part ūüė¶
  18. I have also been discussing the technical aspects, read coding, with one of my IT friends. I suck at coding and am hoping he will be able to grant me assistance even if it is from a long distance

 

Ok now, onto the explanations:

The changing of the design came about for multiple reasons. One the coding for the cutter I was originally working on was a whole lot of BS. When I say BS I mean that it was incomplete in several different ways and wouldn’t do what I needed it to do. My other reason was purely because of aesthetics. I got to thinking about how the final piece would end up looking and decided that an old scanner body was not the looking I wanted to achieve. Hence, the change in the design. Now the biggest downfall to this change is the fact that this new design is going to add to the cost a bit. It’s something I can work with, but not something I am thrilled with. The trip to Home Depot for building materials cost $30. And the order from Amazon ran me about $150. (I’ll post a breakdown of my costs at the bottom) There is a bonus to my change in my design though. I will be able to work on slightly bigger surfaces. I will have about a 10″x14″ surface to work with rather than an 8″x10″ surface. This will grant me a greater range of what I will be able to cut and create.¬†The other reason for changing the design, as I mentioned before, was the exterior aesthetics. The new design will allow me to do more customization of the outside. With this new design I am going to have an easier time making it a color that appeals to me as well as etch some design on the sides so that it will be prettier. So as you can see I think that the changing of the design will ultimate be a marvelous, but expensive, plan.

The test cuts on both vinyl and on scrap bits of acrylic… The logic behind this is to see how the acrylic looks when it is etched on. The black turns a deep shade of grey. I am going to do a test on the red I procured to see how it reacts to an etching. I am thinking that it will turn a shade of pink. Pink is not the color I am going for, but I might be able to layer some vinyl over it, or maybe use clear and do an underlay of vinyl coloring. More tests will be needed to cement a plan. I enjoy the testing part very much, because it makes me feel like I am making some sort of progress.

Here is what I still have to do (but not in the order they are listed):

  1. Cut the wood for the inside and outside bits of the cutter
  2. Assemble the inside frame
  3. Order the required rod for the system
  4. Wait for my mechanical bits to arrive
  5. Assemble the mechanical bits
  6. Run a test with the red acrylic
  7. Get the coding set up to run
  8. Figure out what I have for missing pieces and GET THEM
  9. Work on making more of the bunnies digital (I need 9 and have 6 done already)
  10. Get the following:
    • 1″x1″x1″ aluminum block
    • TIP122 100v 5A DIP Power transistor (general purpose)
    • .3135″ I.D. x .4395″ O.D. x .5″
    • 18-26 gauge solder wire
    • 2) 5/16″x18 steel rod
    • 2) 5/16″x16″ steel rod
  11. Get pieces 3D printed for the assembly
  12. Not stress about this so much. Yes, I added this to the list because It keeps happening
