Dear blog followers,

Sorry I haven't been keeping up with the blog. I will use this post to catch you up on the last few weeks.

 Much progress has been made on the laser cutter. I have acquired the Raspberry PI that I will be using to govern the hardware, and the stepper motors and stepper drivers. I will discuss the BOM of parts here and later present the CAD model.

Here are the parts that I have sourced:

I am still waiting on my tax return to purchase the rest of the parts. There are some McMaster parts that I need to order as well, specifically 80-20 beams and connectors to join them together.
