Dan,

I know this is late, (didn't get a notification) so I hope it's useful. Ballscrews don't work in a manual mill. They have no holding torque and rely on the holding torque of the motor...

Just delete the B when you copy and paste.

You just get the R8 spindle, not R8 and R4.

Interesting to see that. AT doesn't have the datasheet for it displayed on the webpage, and searching for KL-8070 only brings up the kit with the pictures of the other driver in it, but they have...

If it goes 50% too far at .005 and .010, does it go 50% too far at 0.050, or 0.100, and so on? That would say you have a steps per inch problem.

I spent a little time on Automation Technologies...

First off, what Ken226 is saying is exactly right. I use the KL6050 drives that Hoss had in the parts list I bought, but the motors are the most common 200 steps per revolution, my drive is set for...

When you get your Kickstarter URL, would you post that?

I was reluctant to answer this because I didn't know which screws to talk about. The 704 itself is metric, tapped 6.0 x 1.0 mm, but that's not a motor mount, that's the extension that leadscrew goes...

Count me among the folks who would like to help, but don't know enough about the boards.

What it sounds like to me is either a real intermittent connection or something that makes it not work as...

Something told me to restart Mach3. I did, and now it works.

Onward to trying to zero all three axes!

The machine is in inches and has never been run in any other mode.

No material offset. The version of Mach is the .062 that Warp9 recommends. I've been running the combination of the...

I'm having a problem getting the 2010 screen set to work with Mach3. This is the Simple Auto Zero, the single down arrow.

If I understand the manual, it's supposed to lower the probe in the...

I found a "hardware store" 3/8-16 nut was too thick, but a good width to use in the slot. I could shave them back on the lathe pretty easily so they fit. The easier way is that a 3/8 bolt head...

Thanks, Peter. Nicely done.

Roger that. I was just hoping someone would chime in with "I have that table - a 3/8 set works fine", or I need a Metric set, or something.

I see some square 5/16 nuts that are .547 to .562...

I just built up my 4th axis using the RDX table that you used, Hoss, the 1990-0015 from Wholesale Tool.

I thought the 7/16" Tee nuts and bolts from the mill would fit it, but they're too...

That's wisdom. If it ain't broke, don't fix it.

I've gotten into too much trouble over the years ignoring that advice.

Thanks! That got it working right.

I did the same with the brains and that worked as well. It's as if my system is telling me it runs some things from different directories than I think. I...

I just bought the 2010 screen set and did the installation. The installation failed.

I get the attached display. Almost nothing except some boxes and the current settings of the DROs in Mach3....

Thanks - that's what I've been doing. I was thinking of making the accordion folded cover for the Z-screw removable and oiling the bottom.

I was concerned the plastic bushings on the ballnut...

How do you oil the Z-axis ballscrew? Hold the sponge vertically, or just shoot it with a spray of oil?

* 3d printing the "phase 1" parts. Hoss mentioned most of the STLs being "untested" in his documents, but have they been tested since? Is it a viable plan to print those parts, assemble the mill with...

In case someone someday should stumble across this looking for the answer, Automation Technologies helped me resolve it.

Both SW4 and SW6 need to be "up". In the documentation I got from their...

I have an odd question that I hope someone has seen. It's in the electronics, and I think I've ruled out everything except for the C35 interface card from CNC4PC.

The KL-6050 drivers have a...

The corners of jam nuts would hit the bored hole on the bottom half. I could see that the mount was offset compared to the ballscrew. I think I shaved like .010 or .015 off the bottom part of the...

It's done! My machine is fully built up and running just fine on all three axes.

Couldn't have done it with your help.

At this point, the whole project isn't done, but I'm moving...

In case anyone stumbles across this, the ballnut flange wasn't my issue. I found the binding in my motor mount and once that was resolved, my machine moves just fine.

Another question, Hoss. I noticed while getting my table to clear the hoses that sometimes it felt like it hit something hard while I was sliding the table back and forth. I saw some debris on the...

I have a tendency to suffer from what they put in that old saying, "when all you have is a milling machine, every problem looks like milling operation". (or something like involving hammers and...

After sleeping on this, I think I see another way to fix this problem besides cutting away that corner of the table.

Cut away the ballnut mount. Specifically this web of metal. (Crude...

Well that would fix it for sure, but I don't have another machine big enough to do that.
