The right way...couldn't tell ya...what I did was about an 1/8th turn at a time till the dial indicator on the end of the screw didn't move anymore when I changed directions turning the screw. I'm...

I installed AC bearings on my Z axis ballscrew when I did my CNC conversion. I bored out the lower bearing block and used 2 AC bearings in it and replaced the upper bearing with a ball bearing that...

I'll check when I get home late tonight and see what the directive was from the users mailing list, but I think devilspie sounds familiar. If it was something different I'll let you know.

I used a 3 pole contactor - the switch for F/R is a 3 pole switch which closes another signal line as well as connecting the DC lines to the motor.

Haven't seen it yet, just saw the ad posted and responded but the poster hasn't replied yet. I hope it's not sold as I've been watching for a used SB for a while and one FINALLY popped up. ...

Ok guys looking for opinions - all are accepted.

If you found this advertisement

And the ad's asking price was $300.


How bad of a condition would you let the lathe be in and still say yes?

I used that same head for my X3 conversion and had no problems. When you calculate the RPM & feed based on generic SFM and chipload recommendations you don't run very fast once you get outside of...

Unique idea. I'm sitting here kicking myself saying - why didn't I think of that?!?!

Thumbs up.

Looks very nice. You'll like having everything in one box - glad you were able to find one reasonably. Keep the pics coming, we all love machine pron :)

3.5A * 3 motors * 2/3 = 7A. Typically I've seen 2/3 recommended as the powersupply factor since rarely will all 3 be pulling max torque at the same time. Others say add all three and add an amp for...

Since it's a multicircuit ballnut from my interpretations of the nut, it probably isn't going to as big of a problem. Where you will see an issue is probably skidding and errant recycling of the...

Matt - Definitely investigate increasing the pulley size, I know my setup is over geared thus limiting my Z rapids, but not overly detrimental to performance. By increasing your gear ratio you will...

FTP Added -

I have now setup FTP for transfering large images. I obviously don't want to post login info so contact me at the email in the previous post and I'll forward directions for logging in...

I believe I found some at Radio Shack and some at the Local Hardware Store in some of the small parts drawers in the electrical dept. Not a big box store, like a True Value or ACE Hardware or...

Fogging oil also is good for short term open-air protection. I use a Rustlick product for extended duration protection as I encountered a rusting problem after an extended period of non-use and an...

I had a little bit of that when I was still using WD-40 as a cutting fluid (first couple days of the machine). Since then I've been using Rustlick WS5050 without trouble. Not much gets onto the...

Hey we all had to start somewhere! Welcome to the 'Zone!

For the P.S. you could probably get by with cheap PC power supplies converted for on-off use (get the right connector and you can handle the conversion as a snap on so replacement would be a swap of...

For anyone running a machine on EMC2 -

As some of you already know I preach the virtues of EMC2 :)

At the NAMES show in Toledo April 18-19 there will be a booth and a couple of EMC related...

Any details on model #'s ? I looked through the Grainger catalog and didn't find anything that seemed like it would fit the bill (a while back) and to the best of my recollection they carry pretty...

Looks like a sound idea - will you share the plans once you complete them?

They're also not 6ft long... I agree, 20-18ga is best. Mine are not shielded and I haven't had any interference problems. There is only one point where the 3 axes cables come together and that...

DISCLAIMER - This is a tongue in cheek post :)

EMC is idiot proof - it keeps idiots from running complex machines that can kill themselves.

Bill Gates would never publicly admit he was using...

Ditto on HimyKabibble's post - I've used my boring head several times since CNC'ing. It leaves a much better finish than an interpolated helical milled hole and is much more precise - bearing...

Used the cable I mentioned in my last post. Not sure about the max amperage, but they have beefy contact area and haven't had any problem running for a long time sustained on my machine. The...

For cable to the cables to the steppers I used a 4 conductor 18 gauge cable from Home Depot (forget what it was called, I had a spool of it from a previous job). For connectors I used Ham radio...

Though he did say "under the misapprehension that a CNC machine will automatically produce more accurate work than a manual machine" which I don't think really conveyed what he meant well. What I...

If he did that by hand I'd want to go and shake it. :) (disclaimer for the old-timers - I am not saying that it couldn't be done but the time inolved [assuming a reasonable hourly rate] in setup and...

Looks very nice - keep the pictures coming :)

Another wonderful EMC example fitting.
