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

g32 z-0.25 y6.2 x10.2 i.1

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

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?
