How to generate g-code to mill flat surface

[pminmo]

This is probably a really dumb question, and I'm brain dead at the moment. I need to mill a surface 6" x 10" flat with .125inch end mill. Is there a quick and dirty way to generate the code for Mach3? Dept of cut I would handle via multiple iterations of the same code.

Mach3 has a "surfacing" wizard

I used the Probe Cycle command, in TurboCNC, to mill a surface.

This line does multiple 0.1" passes, to a depth of 0.25".
It also covers an area 0.1" larger, all around, using a 0.1" overlap.

Why would he need to use a 1/8 endmill?
-He broke all the other endmills.
-The largest shank allowed in the spindle is 1/8"
-The spindle only has .01hp driving it.
-The spindle runs at 100,000 rpm and 1/8" on down are the only ones that won't burn up.
-He likes the sound of the router motor screaming for hours on end while he gets a few winks of shuteye....the 'white noise syndrome'.
-Setting a new record in Guiness for "largest surface planed with a 1/8" endmill."

Thanks guys, I figured out the mach3 wizard. Worked great.

Hi pminmo,

I haven't figured out the mach3 wizards, when I type in a number it changes back to some default number. I switched from Qstep to mach 3 and haven't used mach enough to know how it all works yet I used kippware for the above g-code.

Hi pminmo,

You MUST hit enter after typing in a number, ANYWHERE in Mach3

[motomitch1]

Thanks Gerry

That was it

[pminmo]

Yep, I learned the same lesson fooling with the wizzards. Couldn't find anything in the documentation. Then all of a sudden something worked, scratched my head as to why, then a couple of more trys and got it. Wow something so simple was so elusive. Guess too many point and clicks in my brain!

[motomitch1]

I gave up because I thought it was a option that i didn't have, them wizzards look pretty handy.

Whats wrong with using the jog keys in mdi mode?

Whats wrong with using the jog keys in mdi mode?

Stand at the machine pushing or holding buttons for an hour
vs.
Do something else while the machine does the work.

I too, have had the same problem... What a simple solution to the wizzards or the conversationals just change the number and hit enter... I felt so stupid, Before I called Art I just pushed post and in note pad I just edited what I wanted the numbers to be. And I told myself that can't be the way to do this. So I emailed Art and I got a one word email back... ( Enter). When all else fails email the guy who wrote the program. Works for me every time. Besides he is a nice guy. Just like Gump said ( I don't know much about cnc programming, but I know Art. And thats all I have to say about that.

Also to have the wizzards or the conversationals it's a 50.00 fee to licence your software thru newfangledsolutions. And then your Mach 2/3 will work just fine in those areas. Another hard lesson like the word ( enter) Now it's simple...
