Had no money for the big CNC I designed (its like 1300 cuz tariffs) so building a small one using parts from a workshop. just need a bit of funding for the stuff I don't have. basic idea: Dissassemble a broken lulzbot TAZ Pro. The double Z-axis become the Y-axis, the bed becomes the X-axis, and a spindle will be mounted above, stationary in X- and Y-axis but will move on Z-axis using the threaded rod from an Ender 3. Electronics will be CNC Shield because I will just be reusing the Nema17s from the printers. Only funding I need is for electronics and the spindle.

Added Z-Axis Prototype for the CNC

Background (since this is the first devpost):

I had planned to build a large CNC (42x42in) for my robotics team, but, due to tariffs and our team’s budget getting cut, we would be unable to fund it even with hackclub help.

While we may have little money, we have about 13 years of junk in a workshop. We have a bunch of broken 3d printers, one of which I am repurposing to make a CNC. I know its super underpowered and jank, but it would be fun and will probably work if I am careful with the design.

Today I designed the carriage for the spindle. I based my design off of an Ender-3 Z-axis, using its threaded rod and v-rollers. However, after some reconsideration, I will probably swap the grey plate with the clamping mount included with the spindle so it can be mounted higher up.
