I’ve got this chinese 3040 CNC frame some time ago from RATTM MOTOR CNC on aliexpress, for just US $ 536.07, shipping included. This is not a ready-to-use machine; you should put your own chains, steppers, stepper mounts, controller, etc.
This frame looks pretty good to me; It comes almost fully assembled and every axis has a pretty good sliding action. Of course you should clean the whole thing and re-grease linear bearings and ballscrews before use. Please note I did choose the version with detachable spindle bracket, so I can install whatever spindle I wish.
I’ve just finished installing wire chains, steppers and tested the whole thing. Next step would be to make an adapter to mount my 12.000rpm DC spindle.
I’ve been lazy. This thing has been gathering dust on my desk for several weeks. Desgined to be cheap, lightweight and cute. Powered by Arduino and GRBL.
Will this cut anything? or would be just a piece of modern art? Of couse, if this doesn’t work, I would say it was just a learning exercise, and use it as a paperweight.
Don’t ask for plans, this isn’t the diy cnc machine you wish to build. And I know, I need a better spindle.
I wish to start to publish some cnc stuff videos on YouTube, so here’s the first one.
In the next one I will show this babe in action.
I know, I know, a Mitutoyo Micrometer and Caliper set for US $60, shipping included, can’t be true. Chinese tools aren’t so bad, but these Mitutoyo chinese counterfeits are a joke.The mic doesn’t even look like the real one, and the caliper is the typical chinese cheap caliper (well, a little bit better may be, but not a Mitutoyo). The mic is usable, but I think the caliper needs some tweaking to make it a worth tool. The seller, jingshengyang2088, has a 99% positive feedback. Lesson learned.
