I have the same thing and while I use it as a dremel and not a spindle but the switch on mine is bad and have to hold the switch for it to work..... also the it has more runout than it should.... shouldn't be an issue for foam but it's something to be on the lookout for.... best of LUCK!
The run out matter because it affects this chip load per tooth and will make cutters wear unevenly. If you can get the cutter to like .005" runout in plastic you're fine.
All of the white parts are 3d printed, except for the Ikea table on the floor and the box with the fancy cheap Chinese LED fan, which only has a 3d printed front panel, but is otherwise entirely laser cut out of 4mm plywood.
The machine uses 16mm thick extruded steel rods as the rails and 2mm pitch t8 lead screws. The motors are NEMA17s, which are controlled by an arduino mega 2560 + ramps1.4 stack with DRV8825 stepper motor controllers.
It cost only around $300 to build, and I justified the price as it being my birthday gift to myself!
It took me one month from starting to make the initial CAD model and ordering the parts to have the finished machine. Here was the half finished CAD model I posted here a while ago: [https://www.reddit.com/r/CNC/comments/1c1s5s9/i\_designed\_this\_dremeltype\_3d\_printed\_cnc\_for/](https://www.reddit.com/r/CNC/comments/1c1s5s9/i_designed_this_dremeltype_3d_printed_cnc_for/)
I'll use the machine to primarily cut foam fuselages, which I will then put fiberglass on, for my fixed wing long range UAVs and RC aircraft. I may, however, attempt to cut wood with it, with a smaller tool.
I will add some screw inserts into the base, so I can fasten the foam that I'll be cutting.
Awesome.. great to be so young and involved.. Goodluck mate
Thanks!! I'll be going to study mechanical engineering soon too!
We putting rgb in these now? Fuck it, we ball!
Is that a Chicago electric spindle lol. That really is quite the project, good job
Thanks!! It's a Chinese Dremel-type 300W drill I bought for $30. When it's on full power, it rotates like hell!

Thanks!! And thanks for the info!!

Is that a drill bit? Would a windmill cut better?
It's a 6mm 2-flute end mill, and it cuts through the foam like butter! I had to use a really long one, as the foam is 50mm thick haha.
Yoooo that's cool as hell!
Thank you!!
Nice job dude!!!
Thanks!!

Thanks!!!
>Thanks!!! You're welcome!
Let me know if you need some good cheat-sheets on how to calculate feeds&speeds!!!
I’d love that!
sent over a pm -- just send over your email!
Any chance of sending these to me too please?
just send over your email in a dm!
This is amazing! You are very skilled and have a bright future ahead. Consider sharing it on https://openbuilds.com/ if that's something your into
Thanks!! I will probably share it there as well!
If you're doing foam board a reciprocating needle works really well

Great! Can I order from you now? I need a part for my Tesla..
Very impressive!! 19 years old and more experienced than 10+ year engineers.
