hi everyone-

we moved the "blog" section of the website that contains all the info on our homebrew cnc mill to another server and are working on getting it back online. that's why the links don't currently work. but keep clicking and it just might..

the project's still alive and well!  :)

thanks!

Fignoggle,

Thanks for the reply,  yes I did make a y-axis bearing block,  I went kinda cheap with it though.  I just used 2 ball bearings and preloaded them to each other by shimming between the outer race.  This didn't leave much room on the stock leadscrew, just enough to get the pulley mounted.  Next time I take it apart to adjust or tune things I will take some pictures incase someone wants to do something like it.

Arn


hi arn-

that'd be great - always nice to see other x2 conversions :)

our y-axis block looks like this: http://www.fignoggle.com/machines/x2mill/howTo-upgradeScrewNutY.htm

are you using split nuts on the acmes on the x/y axes?

not sure abou
I recently upgraded my mini with imperial lead screws. I'm now thinking of converting to cnc, but one thing has me vexed. The Z axis is rack and pinion. How will the difference between rack, and lead screw, affect the Mach configurations? Also what size motors to use to move the Z axis. All that cast iron is heavy. Any assistance will be greatly appreciated.

hi-

you can leave the rack/pinion in place while the leadscrew drives the z-axis. for example, in our conversion, you leave the rack/pinion in place so that you can use both cnc and manual operation. if you go cnc only, it make make sense to remove it. when you go to confugure mach, you enter in the "steps per unit" (http://www.fignoggle.com/calculators/stepcalc.php) for the leadscrew. hope this helps!

disclaimer: we also sell plans, so please factor that into our reply. :)

hi all-

finally joined the forum! we've been working on a home-brewed cnc vertical mill that has a work envelope comparable (or larger) to a sieg x3 that can be disassembled, can fit into a car trunk, has a total materials cost of $1000 or so, and with accuracies of +/-0.001".

we were planning on using a x2 motor/controller but may just go with their spindle and use another motor/controller and have it all run via nc. this is just a prototype for now so it's pretty rough, but promising!

the blog is located here:

here's the preliminary drawing:


and the finished product:


here's a video clip:

thanks for listening and enjoy!

oh, it's going to be run with mach of course :)
