I have pulleys for 3:1 on my Z-axis as well!

However, this interesting response was a reply when I asked the very same question:...

It all depends what gear ratios you want to achieve. Generally speaking, a direct drive system would use either Oldham Couplings or drive pulleys of the same diameter. For increased torque and slower...

I'm afraid that as precision increases, so does the cost. I wouldn't look at anything less than a closed-loop drive system...ideally go for Servo drives rather than stepper motors. The main issue...

I've still got the 600W DC motor and associated electrics from my Warco WM 16 if you're interested?

I assume you meant AC control? If so, the mechanics are probably the hardest thing to do...in particular getting a motor small enough to fit the machine without giving up too many horses.

Obviously the OS is more important than the software. If the OS is unstable or unreliable, then we can't expect any software to be stable. But yes, at the end of the day all we need is a CNC...

99% of the time, they will choose Windows because they are already familiar with it. People don't like change, no matter how easy or difficult it may be. That's why M$ have done so well...

Well, my experience with the LinuxCNC forums is that they've always been helpful and quick to respond. Most of the developers actually run CNC machines, so understand hardware as well as software. I...

In addition to this, particularly if buying from eBay, make yourself familiar with what's in the the "machine tool sets". Some sellers start off with these but sell the contents individually to make...

Is this for counterboring caphead bolts? If so, why not use a proper counterbore?

Just found this. Apologies if it has been posted before:

I'm dithering about with a Warco WM16 mill which I plan to convert to CNC but was planning on leaving the standard lead screws in and seeing how it performs. If it turns out to be crap, then I'll...

Looks OK in DraftSight on my Linux machine.

Geoffrey, if you click "Go Advanced" in the bottom right corner of the "Quick Reply" box, you get some extra options, one of which is "Add Attachment". the icon looks like a sheet of paper with a...

Personally, I wouldn't touch anything Chinese. Actually, that's a lie because most kit is made in China nowadays. What I mean is...I wouldn't touch anything unbranded. It's all about guarantees,...

Probably a bit late, but I'm a C&G qualified welder. For home-use MIG, I use CO2 without any problems at all. A lot of people say "don't use CO2, too much spatter, etc" but you'll find that 99% of...

Just discovered this rather nice FREE software: QElectroTech: Welcome, presentation

It's still Beta, but is available in the Linux repositories. Also works on Windows according to the developer.
