I'd like to thank everyone for their quotes, one has been chosen, this is now closed.

Thanks for that important point. I will be doing some homework on steel to find out what should be required.

I'm converting a Porsche 944 from gas to electric, I need a steel coupler to connect the output shaft of the electric motor (1 1/8 keyed) to the torque tube splines (Spline count = 23; Pilot diameter...

It does appear to be floating because the LED was mounted to the top of the spindle, which is probably 12" above the table surface at that time.
I didn't actually cut any material, I just ran the...

Switcher, I would like to thank you for a couple of DXF files that I used from your Blog. I was doing something a little different for a photo group that I belong to, the results were quite...

Mouser part numbers you could use are:
TIP147 = 512-TIP147T
D1 = 512-1N4007

If you haven't already purchased the screws consider a 1/2"-10 acme (2 start) which gives you 5 turns per inch.. and resonable cost anti backlash nuts are available from dumpstercnc.com I went with...

The machine is coming along nicely, I did the first cuts on the weekend.

Awsome thread, I spent the whole morning reading it.. wow..
great interactive product development.

G-Pak for the set of 4 w/MB etc.

I'm not sure if I would build a rockcliff type machine now that I've gone another direction, I guess it would depend on your budget and the type of work you would like to do with it. My machine is...

That's a nice machine, the t-slot extrusion is great to work with. I like the fixed gantry design, I'm thinking of making a pcb mill of a similar style when my first cnc machine is done. It just...

I'm in Calgary,
And I have to admit that the free stuff took my build to the next level. I actually purchased the rockcliff plans, good for an entry level machine but that's about it. What I'd...

Thanks airbrush,
As for the t-slots, I got it all for nothing. It was salvaged from a machine collecting dust in the corner at work. The only drawback, I had to adjust machine dimensions to fit...

Here's a little on my cnc project.
the entire frame, including gantry, z axis etc are made from t-slot extrusion.
I used bosch rexroth, salvaged from some old machine at work.

Hi Glenn,
I'm also in Southern AB, Calgary to be exact.
I also bought the rockcliff plans, as a reference though, and I designed my own machine based on those principals and many other ideas from...

If you have a business/work address you can have your stuff shipped to , McMaster Carr will still ship to Canada. We get stuff from them at work all the time so I ordered my acme screws and some...

Hi Bob, thanks for the link.
That's quite the impressive machine you've built.
The only weak link I see in my machine sofar is the main axis rails, I'll have to find a way to support them in the...

Hello all, I've been browsing this site for a couple months now, but as my machine actually starts to come together I thought I might post what I'm building. I started off designing an MDF machine,...

Hello all,
the problem was windows driver/update related.
I formated the computer and reinstalled windows (using the F5 install method noted in the mach 3 manual as "standard pc") installed all the...

I did the reboot as required after the install.
But I'll try the things you recommended, thankyou for the very promp help.
A few times in Mach 3 I would get a "watchdog driver" error that would...

Hello, this is my first post here.
I've been reading this site for awhile now, and it seems loaded with info and great people.
I'm basically done the "collecting" parts for my 3 axis cnc router....
