I haven't converted yet. That was my intention when I got this 8 years ago; I bought lead screws, ballnuts, and motor mounts, too. But, life got in the way, and here I am, back again. I'd like to...

Greetings,

Sorry for this throw-away thread, but my 'search mojo' seems to have abandoned me. I know there are threads detailing how folks set up new G0704 mills, including disassembly,...

Thanks for the replies. Lots of good information.

I read the K-Flop manual. It seems like industrial strength stuff. It can control using linear encoders for position feedback.

What manual...

O.K., another week or two of thinking and researching for this project leads me here: closed loop operation.

Closed loop operation, i.e., steppers driving the axes, with linear encoders providing...

I think your expectations may be too high. I'm a bit puzzled, though, having just purchased the same machine (received last week, not unpacked yet); where did you get the notion as to what the...

Thanks!

Thanks, that's cool. I haven't come across any threads yet for guys here using servos. Are they direct-coupled, or driving through a reduction, i.e., belt or gear reducer?

Cool!

So, I assume you are direct-connected to the stepper, the stepper has 200 steps per rev, your lead screw is .2" per rev, and your are microstepping 8:1 to get to 8000 steps per inch?
...

A couple of things. First, I may have introduced a terminology collision here: "hybrid" can refer both to a stepper motor configuration, as opposed to permanent magnet or variable reluctance, as...

I read this thread with great interest, as I have the same question as the OP. There is clearly a lot of knowledge and experience among the participants in this thread.

The idea of a...

BDTools motor mount kit and CJA Masterworks ballscrew set arrived today. The mounts are beautiful. The ballnuts are as I imagined, the Roton ballscrews with a 15/16-16 UN thread mount.

I was...

Has anyone taken an analytical approach to motor selection for this machine?

I confess I knew nothing at all about stepper motors until this week. I read what I think is an excellent paper from...

O.K., I see. Thanks. Can't wait to take the mill apart and actually get my hands on the pieces.

My BDTools motor brackets and leadscrews arrive today, too.

Wow, man, I feel so stupid. I'm still not getting it. I even googled "pinch bolt" and still couldn't figure it out. :)

I am further confuse by your saying that there's a ballnut involved. I...

I was following you right up until you said "pinch bolts." I don't know what you mean.

By the way, the machine arrived today; order was finalized Monday afternoon, delivered Thursday around 1:45....

There's a long story in answer to that, and the answer is no. At the time of the purchase I was not aware of ballnut mounts. It turns out that the ballnuts I'm getting (haven't received them yet)...

I hesitate to start yet another vanity G0704 build thread, as there are so many great ones here already, and I can only aspire to the heights that others have achieved.

I have ordere the mill,...

Not yet, should have them in a few days. Here's auction I won:

In retrospect, I probably should have just...

I bought the mounts and screws together from someone who abandoned the conversion project.

It occurred to me this morning that the ballscrew mounts might not be included. Duh!

Does anyone...

Thank you for this thread. I have just committed to a very similar project, CNC'ing a G0704 with the BDTools bracket set, and CJA Masterworks ball screw assemblies. I ordered the mill yesterday.

Thanks!

Re: which "kit" - I haven't selected one yet, I was browsing eBay. I need a couple of NEMA 23 steppers plus 1 NEMA 34, for the X, Y, and Z of a Grizzly G0704. I still an very new at this and...

Thanks - tried searching on that auction number and came up blank. Can you please re-check it for me?

Thanks! Duh, do I feel like a dummy! That's one of the reasons I started a thread asking for book recommendations. I really don't know what a complete system looks like.

Thanks,

Newbie question:

I have Alibre CAM 2.0 Basic, which is the version of Visual Mill that is integrated into Alibre Design, and "free" with Alibre Design Expert.

I have just started the tutorials....

Thanks! I have since found a company that makes controller boxes specifically for CNC controllers, but it adds up to a lot of money quickly. It's cnc4pc.com. I like that they have brackets for the...

Stupid newbie question:

I'm shopping for a stepper kit, and I've seen, for example, kits consisting of three stepper motors, a breakout board, three stepper motor driver modules, and a power...

Greetings,

I'm new to "home" CNC, 'though not to engineering, metalworking, and computers. I think that I want to tackle a CNC conversion based on the Grizzly G0704.

If one were to purchase...

I'm very new at this, but I would do the following:
