New CNC up and running, Need some G-code

What kind of controller is hooked up to your mill? What tools are you going to use? What's the envelope of your mill? Are you writing code by hand or using a CAD/CAM program? I can send you my cam post if you want.

post 29.
Keep in mind this is for a mid-nineties fadal with the origin shown as below. Three tools, (if I remember correctly) a .250" drill(T20) , a .375" em(T21with 1.96" reach ), and a .250"em (T22 with 1.40"reach ).

Good luck, and I assume no responsibility for any crash.

ETA: if there are any changes you want made such as moving the origin, or increasing/decreasing depth of cut or side step size, let me know and I'll repost it. If you know what format your mill likes, I'll see if any of my stock post libraries can spit out your format.

wish I could afford the big toys :P

That all sounds like such a hassle to setup. Best just crate it up and ship it off to me

Nice machine. That should really open up the possibilities.

Thanks Guys, Like I said we’re just getting started, but I do understand most of this.

Lostsheep Thanks for the code. It’s great to see it and to have something to compare the code we generate to.

We loaded some solid models into SprutCam and simulated cutting AR-15 lowers from billets. It worked great, but SprutCam asks a lot of questions I wasn’t real sure of all the answers. It’s a steep learning curve.

SprutCam used what information we gave it and did what it could with the tools we designated. I’m sure we could cut out some steps if we knew all the answers, but SprutCam only did what it could without going too far. I’m sure the answers will come with experience.

PM your email address and I'll send you code for FCG pocket milling for a Tormach.

[VaderSpade]

PM sent Thanks

[Lostsheep]

I recommend you get some inexpensive foam, plastic, or wood and try to create the fcg pocket in that first. It will save you money on material and tooling.

There is a place that sells machinable wax. You can remelt it in your oven at like 400 degrees too if you save the chunks/scrap.

Shouldn't break any tools. Just make sure your feed rates are right. Otherwise you break end mills like me.

Thanks, I built a deck last year with that wood/plastic decking (Trex?) anyway we have been using the scraps for test runs, it seems to work well.

PanchoVilla, I think I have some of that wax. I cast jewelry for a few years and used blocks of hard carving wax. I hope to use the CNC to carve some small parts for casting.

Damn, you can do ~investment casting?

Some day I may ask you a favor...
