3040 Frame

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.

IMG_2350IMG_2351IMG_2359This 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.

Proof-of-concept prototype

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.

IMG_2298Will 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.

CNC Lathe making chips and choosing a video editor

I guess I should have chosen a curvy part instead of this boring one… maybe the next time.

Now some words about my search for a decent linux video editor. I did my previous video using OpenShot; It was a bit crashy and I really don’t like the way it handles titles. So after checking some reviews and doing some tests, I finally settle on Kdenlive, which is really nice.

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.IMG_3106IMG_3107IMG_3110The 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.
