This is the latest project that I made at TechShop Chandler. I wanted to try engraving a logo using the ShopBot. So a grabbed a Nissan logo off the web (I don't own the logo, I just used it as example of something to engrave).
Step 1: Convert logo to Vector
I imported the logo into VCarve Pro, and converted it to a Vector using the software's wizard. Then I had to edit the nodes to simplify the logo to make it acceptable for the ShopBot.
Step 2: Preview of the Toolpath
I told the software to use a 1/4" endmill to engrave the main logo, and a V-bit for the text engraving. Here is the tool path preview from VCarve Pro.
Step 3: On to the ShopBot
Then I loaded the machine code into the ShopBot, installed my bit, set my zeros and starting cutting.
Step 4: Finished product
Here is the finished product. As you can see, the maple split because I shot a nail too close to the edge. The text isn't perfect, because the V-bit was damaged. And I still need to sand it, but overall, I am quite pleased with the potential of the ShopBot.
I am still trying to come up with more projects to take advantage of my local TechShop in Chandler.
