Looking for a parts list for a G0704 conversion. I am in the unique position that I will be compensated for some website work with a machine and all the components I need for the CNC conversion. I need to make this as complete as possible to ensure I don't end up going too far out of pocket to finish the conversion. I do have to keep this reasonable, and would like to eventually add a power drawbar for quick tool swaps in the future as well as 4th axis capable of simple bore/threading jobs....but i can expand electronics later for that. I do want to do mach3 spindle control though. I have the C11 included to allow for that, but not sure what else I need. I will be using Hoss' Phase 1 conversion as a guide.

Also, is it safe to run the machine without it being anchored at first until I decide where I want its final resting place to be? Is there any way to anchor it without drilling into the concrete of the garage? I rent the house, and would hate to mix concrete just to fill little holes with.

Please see attached parts list, and if one could help me flesh it out, I would really appreciate it.

I am also looking for a basic tooling list for this mill - I have no mill tooling at this point. I will also get a bench grinder and bandsaw soon....this chop saw of mine just isn't going to cut it. (No pun intended.)

Thanks,

John

Oops, forgot to attach the PL.

Off the top of my head.
Theres about $20 of stock in the phase 1 conversion.
And another $20 in fasteners, though it's probably less for the phase 1
You'll need the oldham couplers
You'll need a couple of Taps, 1/2-20 and #10-32 I think
You'll need a box to put the electronics in and connectors to plug the steppers into, a power switch, an E-Stop button.

A Copy of Mach3 unless you plan to use EMC2.
A computer to run it on.


Do you have sufficient tooling to make the stepper standoffs?

I assume your not doing the BallScrew conversion?

Stock and Fasteners shouldn't be a problem, nor the couplers. I have the taps, and can get a box easy. I have the steppers, a power switch and need an e-stop button.

Got Mach3 and a computer.

I do not have the plans, so I'm not sure if I have the tooling. Like i said, I dont have any mill tooling, so probably not. I do have a drill press and a chop saw and dremel at this point. Not much. haha.

No ballscrews yet. I'll use the Mach3 backlash comp for now, and upgrade at some point in the future, if I actually use the mill enough.

[rpovey]

You should be able make the standoffs with the manual mil.
There isn't much in the phase 1 plans that's got critical tolerances as far as I can see.

Some basic measurement equipment. Calipers, 1-2-3 blocks, Machinist Square, Test indicator. . . . Etc

A pretty good vise, Hoss uses the Shars 5" and did a little video on its squareness and I was pretty impressed.

Hoss's website (g0704.com) has a list of suggested items and spec's to help you out.

Thanks for all the help all. How do I use it without bolting it down? Any ideas? Do I need to make a box that I can fill with concrete/lead ingots, and sink some anchors into that, then attach the mill stand with that? That way it is weighted, but removable without damaging the garage floor.

Some guys are using large diameter leveling pads. But i think they had to drill some holes further outboard to give the machine some stability. Im sure someone will chime in shortly. The devices look like hockey pucks with a bolt through them.

You can find leveling feet all around, that's all I'll be using since I don't want to bolt it to my bedroom floor.
It's been free moving for a year and a half but I keep a bit of weight inside the cabinet to prevent tip over.
The tooling list can be seen here, not much to it.
Shop Info
Fractional drills that are close could be substituted for the letter and number drills.

Great. Thanks for the link. I will keep a coolant tank and 2x 50 pound bags of lead shot in it to give it a quick 100 pounds...and can remove or add as required. I do the same thing in my gun safes to make them harder to move....500 pounds of shot in the bottom of each of them.

I pretty much have or will have the tooling, so that will make life easier.

[j.steensen]

On the C11 and Keling Drivers, is the pin spacing standard so that I can use flat cable, pin headers, and locking IDC connectors?

Will the LMS Z-Bot work with a G0704? (LittleMachineShop.com - Power Drawbar, R8 Mini Mill)

Never dealt with pneumatics, so I am a little hesitant to roll my own at this point, though I would like it to be solenoid controlled in preparation for a future ATC installation.

[hoss2006]

The zbot is made to fit the x2 head which is about an inch narrower than the g0704 head.
It's also a design that puts the full force on the spindle bearings, it's not too terrible
because it's only good for about 700lbs. It's a light duty system.

[j.steensen]

Then what modifications would I need to make right off the bat to your system, Hoss? Or is it straight across compatible?

God, I've been working around engineers too much.....you should see this BOM I've built up, with supporting SolidWorks models of everything, with full motion/mechanical mates for later simulation and testing.

[j.steensen]

Dumb question. Just realized how this mounted to the head. I would have to lengthen to the width of the G0704 head.

[j.steensen]

Would the nominal width of the G0704 head be 4.724"?

[hoss2006]

yes

[j.steensen]

And would this work to drive the power drawbar: McMaster-Carr ?
