Writing our name
Writing our name
We were instructed to write our names using only the desktop mill, so to start off we made our names in a website with a grid (Virtual Graph Paper) so it was easy to write the g-code. We wrote the g-code in notepad and copied the code onto a flash drive them uploaded it to the desktop mill with a pen attachment. We would then run the mill to write our name.
My first attempt was a fail and it didn't even look like my name. The pen didn't even get up off the paper to start writing another letter.
My second attempt was way better I realized that the Z couldn't go up to 3 inches (what I had it set at in my code) because the machine is smaller than normal. I also added decimals to all my whole numbers because the machine couldn't read the number unless it had a decimal point after or before it. My first A and N were messed up because I missed adding decimals to the g-code.
My third and final attempt was perfect and looked exactly how it looked on the virtual graph paper website we used. Below is the finished g-code I used and the three attempts I did.

Curvy N
Curvy N
Today we designed a letter that had some curves to it so we could figure out how to code curves using radiuses. I started out designing an N on Virtual Graph Paper .com, I have the ratio of 1 box = 1 inch. The designing went great but things slowed down when it came to programming the G-code, I tried to start out by just manually placing little lines to make up a curved shape but I knew that was going to take way to long and wasn't going to look good. Rick taught us that the code for writing curves was G2 or 3 (for counter clockwise and just clockwise) F50. (feedrate/how fast the pen tool moves) R?? (The radius of the line your are going drawing) X and Y. I was having trouble Getting the radius of the line I was trying to write, I tried to use the website to see the radius by looking at the bottom right corner the triangle was the radius of the line I was making but since I sized up the sketch to real life it was off.
After I realized that the size was off I switched to fusion and remade my N because I thought that I would be able to understand it more, and I did I also figured out that it was easier to get the radius using the measure tool. Below is the G-code I made and used for the final attempt

Fresh Orange
Fresh Orange
Today we were instructed to redraw a picture of our choosing using the desktop mill with g-code. I decided to redraw this fresh orange picture that I found online on a website called "logoworks.com". After I found my picture I put it into fusion to sketch out, so I could have exact measurements and radiuses for my g-code. I had a 5 inch by 5 inch box in fusion that I used as a base for my picture, so I know its going to fit in a 5 by 5 inch box on the paper we're drawing on.
This is how I got all the points for my g-code I had the measure tool to see how far the points were from my offset point/bottom left. This is also how I got all the radius for the curves in the part.
These are the two tries that I did to draw the fresh orange, as you can see on the first attempt its messed up, but on my second and last attempt I got it perfect. On my first attempt I didn't raise the z high enough and it was still touching the paper when it shouldn't have been because it was moving to the next letter, and also I for got to add an X coordinate and that's why its stopped early because it errored out. After I fixed the two problems I also realized that I forgot to add the Z going back down after finishing a letter so I fixed that too. Below is the G-code I used for the final product.
