      Hi Everyone!

      This is my first CNC build primarily created to help me with my other hobbies as well as my interest in design and fabrication. Here you can follow along with me throughout the weeks as I develop and build this small CNC mill. The goal was to keep the budget fairly low while maintaining accuracy and versatility. I currently own a Prusa i3 MK2S, which will be used to develop all of the parts. I have tried to keep all parts both 3D Print-able and mill-able so that I can get the tolerances close to what I'm looking for and then go back and mill all the parts so that the machine can upgrade itself!

      Today I had a bit of unexpected progress! I ordered some hardware from OpenBuilds so I could finally put some of the wheels on the printed parts and have a basic tolerance check. So far everything seems to fit snugly (except the z axis due to a modeling error on my end) and there's no visible play in any of the parts. Below are some pictures of how everything goes together. It's a really simple build at this point so I'm going to annotate it very little for now.

      This is the right side of the gantry, the left side still needs to be printed and I need to buy some appropriately sized screws for the stepper motor mounts. I also managed to order the wrong gear for the stepper motors so I'll need to try and exchange those!

      Here's the z axis, I'm going to add two more wheels to it as well as tighten up that tolerance! I somehow got it wrong by about a millimeter

      This is a spacer that will be used between the Z and Y axis mount to join the two parts together.

      Now jumping forward a few minutes here's a rough test fit of all the parts together! I need to purchase an m5 tap tomorrow (I accidentally broke the one I just ordered...) and print the other side of the gantry and the prototype will be mostly assembled!

      Next will be electronics....


      Here's the original renders too to see how it changes as you follow along!
