Super cheap cnc

I know I caught your attention with the title,so here is the basic rundown.

I designed a 3d printable pen plotter that can be built completely for 75 dollars, counting filament. It is meant to be an easy build and is meant to plot on a 20 by 30 inch sheet of foamboard but can be adjusted for any other material.

I currently cannot build this but anyone who can please let me know and I would love to share this.

Is this machine designed to cut foamboard? If so, I may be interested.

I would love to see your design! It would be awesome to be able to plot on foamboard and other materials.

Would you like to beta build? I will attach a link to a google drive with all necessarry parts and files later.

no only plot for now, sorry

Possibly, I'd have to price it out for Canada first. Sometimes things can be hard to get and much more expensive here.

ok. Here is the link: https://drive.google.com/drive/folders/1e91mUA3JFWH49yW7nc5c8VhnWBpldZST?usp=sharing

Would you have any drawings of the whole assembly? I'm having trouble working out how everything would go together.

Yeah sure, I added the step file to the google drive
and here is a link to view it other than through the step file: https://autode.sk/3JfPiRJ

Very neat design! I wonder if the roller axis could be optimized to use a single stepper motor.

probably, but for me, its is cheaper and easier, as a metal rod, that is 100 percent straight is both expensive and hard to find.

so I randomly foudn the design of this in my list of designs, and would actually like to build it. Here are some photos. Knowing what I know now about cad design, I am surprised at how well I designed this but would also like to modify the design a bit to make it work better knowing what I know now from my experience with building a 3d printer. the main think I want to do, is integrate a 3d printed linear rail into the vertical aspect, as I have tried to pritn one and it works great and it will allow fro teh mounting of many differrent tools, including maybe a drememl at some point or a needle cutter more likely.

the design is honestly pretty good for a sharpie, so I will try as is, and then I will figure out a way to integrate a needle cutter.
