Re: Has anyone built a cnc lathe?

Since this topic has been brought back up, a new development is a board called the Acorn, from Centroid. It's a ready-to-go 4-axis controller that comes with some very well-polished and robust software- as you might expect, as Centroid has been a supplier of industrial-quality CNC software for some ...

Using Carbide Create with drag engraver diamond?

I need to use my S3 (if possible) to engrave some text on some small parts- the text will need to be about 1/8" high and only about 1-3/8" long. I have a(n admittedly cheap) eBay spring-loaded drag engraving diamond bit which should work- it's just tool marking, really, so I'm not terribly concerned...

Re: What about eBay spindles?

Okay, the supplied DeWalt 611 is about 3.5 lb, or 1.5 Kg. The generic eBay 0.8Kw spindle (water cooled, 65mm OD) is listed as 5.2lb, or 2.4 Kg. I could only find one listing that even gave a weight, but one might assume that's fairly standard across the board. That's over half again heavier than the...

Re: What about eBay spindles?

I'd already read Christian's writeup, but he makes no mention of weight apart from the part about cutting down the rather beefy supplied clamp. I'd also read ForgottenCNC's article on his 1.5Kw install, since that's almost the exact spindle I've been looking at (generic Chinese 1.5Kw with ER11 nose,...

What about eBay spindles?

I've gotten my SO3 up and running, and have started working towards the eventual production part I hope to produce with it. Details to come later, but suffice to say that it's a somewhat larger piece (roughly 12"x1.5"x6") and while not heavily figured, there will be some contouring requiring quite a...

Re: Joining the Club

Thanks for the info, guys! I finally had a chance to get my SO3 assembled, wired and running, and of course tried the ubiquitous "Hello World" test: http://docsmachine.com/2016/shapeoko04.jpg Everything worked great- although I will note the instructions I could find on installing the limit switches...

Re: Shapeoko 3 Z-Axis stepper skipping

I had an issue with my CNC lathe conversion, where one stepper, while powered up but idle, could relatively easily be turned by hand. I wish I could say definitively what the issue was, but I know for a fact it was electronic. I could swap leads between the two steppers, and the "weak hold" issue fo...

Re: Joining the Club

Good enough, PDF I can at least print out.

I'm not really a luddite. :) I just don't own an E-reader or tablet- I'd rather put the money into tools and machinery. :)

Re: Joining the Club

In that case, you may find Edward Ford's new book of interest: Make: Getting Started with CNC . -That does look interesting, although I have to admit a bit of disappointment to see it's only available as an E-book. Do you know what format it's provided in, such as a PDF? I don't own a Kindle, etc. ...

Re: Joining the Club

There's no 'potential for dust' with a ShapeOko, there's a CERTAINTY for dust... [snip] As you don't have any dust control, I REALLY, REALLY advise you to use a good mask. some of that wood dust will be small enouh to be airborne for quite a while, and can do some pretty horrible damage to your lun...
