I will take a look, thank you sir,

I'm glad to hear I'm not the only one who is "accident prone":)

Hmm, Thank you for your input,

I was able to buy one a year ago for $43, confidentially this has happened before. I guess that's where my price point was. I found a full set Ball nut and...

That actually crossed my mind considering possible damage to the screw. I haven't looked closely at the screw, kind of hoping I could just get a nut. I have located a nut/screw assembly on Ebay...

Hi Guys,

So after a perfect storm of issues, the spindle of my G0704 conversion slammed into my vice and I couldn't get it shut off for several seconds. I'm pretty sure by ball nut is shot. I...

Hi,

I by no means know what I am doing, but I did not remove the bearings after break in. I figured the added stress to the bearing, pressing them in and out, was not something I wanted to tempt...

Hey guys,

Thank you so much for your assistance, after redrawing the model and starting over on the CAM I had the same misalignment. I decided to check the calibration and found that my Y axis...

I measured how far I was off and it looks like I'm off .025" ???? I guess I was being optimistic. Again, this was with perfect zero settings On both sides. I've attached a pic with a crudely drawn...

Thank you for your replies, I measured the stock that I am using and it does vary from 0" to .003". I should have perhaps faced all sides to get that more consistent though I dismissed this as an...

Hey guys,

I'm stumped on this and just need help thinking this through. I'm essentially milling a cylinder from 1" square stock. I have 1 setup to mill one side using a parallel tool path, then...

Thank you gentlemen,

I cleared out all the excess grease and when tightening the lock nut down onto the bearing I applied just the lightest touch and tightened down the two hex bolts. I ran it...

Thanks for your reply,

I have a feeling I over greased the spindle bearings. I watched a video and the guy used 1cc for the large and .5cc for the small bearing. I wasn't even able to hit each...

Hey Guys,

So I just finished the belt conversion from Benchtop Precision and as part of it, I replaced the spindle bearings (roller) and the upper larger ball bearings around the barrel they...

Thanks guys,

It looks like if I go with the UC400ETH then I will have the option to either stay with Mach 3 or try UCCNC.

Hey Guys,

Well I was trying to isolate some accuracy issues with my G0704 CNC conversion and I ended up killing my PC. Rather than tracking down a base image with windows XP, I thought maybe I...

Well, I'm gonna start here :-).

After about 15 minutes at 2000K the spindle is so hot I can't touch it. I can't imagine this is normal. Once I get the Bearing in, I thing a belt drive may be...

Nice! Thank you

Hope this cuts down on the heat of my originals. I swear I could heat the garage after just a few minutes. :-)

Hi,

Thinking of pulling the trigger in these bearings and was just wondering, did you use the standard number/size shims with these bearings?

Afternoon Guys,

I am doing the infamous conversion on the G0704 and have a couple questions that I can't seem to find the answer too. I purchased the ball screws and electronics from Automated...

Thanks for the help guys, I have a couple 3-axis projects ready to cut my teeth on before I attempt this, essentially routing out parts off of a flat piece of aluminum, but this is my goal.

I...

Thanks for the comments,

Yes I do want to cut it as one piece. It's so small that I don't think I could weld it together, though that would make the process of machining easier. Plus I think I...

Hi Guys.

I've been working on a project that I can't seem to talk myself out of, though I've tried :-)

I drew it up in Fushion360 and am ready to move to the next step. I guess I'm just...
