G-Code, CAD, and CAM discussions / Havin a helluva time!

« on: July 24, 2006, 10:12:56 AM »

Yesterday I was trying to use the somple thread wizard and it wouldnt even bring the tool into the part. I assumed I was putting a wrong value or something in, but now Im thinking there may be something else going on?

Anyway, one of the products I have been making over the last year on my manual althe and mill is some handlebar risers for motorcycles. They are the biggest reason I decided on getting this shoptask with cnc option.

Anyway, I went into a different wizard, for arc cutting on the face. I put in all my values but now its threading Looking through the code it generated, it I and K values but no J.

right hand corner of the part is x1 z0. end of the part is x1 z-1

Arc is supposed to start/end at x0 z-.5 and x.8125 z0

Anyway, are the wizards working for anyone?

Can anyone tell me what this code is supposed to be doing?

General Mach Discussion / Need help again, programming portion (using the wizard)

« on: July 23, 2006, 03:48:11 PM »

OK, thanks to a very cool guy that goes by papa bear (cant remember which forum) I got everything rolling pretty good.

I do sometimes have to keep changing the stepper values (from 20000 to 40000) but I can live with that, long as I remember to check it on each boot up).

My problem this time around (in mach3 turn) is in the simple threading wizard. Heres a screen shot of the values I am putting in..


The diameter of the aluminum bar I am trying to thread is 1.625. not really worried about it being used so the 2 threads per inch I have on the screen is fine by me, this is just supposed to be a test after all..

Anyway, I touch off on the part and tell the program that that point is +.8125 (on the od, center of the part is supposed to be 0 right?) and since I am a wuss i set Z0 at .100 past the end of the part.

Start the program and the tool is making the threads like it should, but dang near .250 away from the part.. so Im just cutting air..

Anyone see what I am doing wrong? This kind of thing is happening with all the wizards I have tried so far..

General Mach Discussion / How do I jog? (yep, another newb!)

« on: July 22, 2006, 10:46:17 AM »

Just got a shoptask machine (lathe mill combo) with the cnc option. they send mach3 for the software. Going through it to learn it as best as I can and I cant figure out how to jog the dang thing. The pdf file that was sent with the program gives a diagram with a jogball (wtf is that?), anyway, it looks nothing like what I have on my screen, matter of fact none of the diagrams or screenshots look like the version i am using. Not a problem not seeing most of the SC's, but this one is confusing me like, well, a newb..

Help please?! lol
