Hi Brian,

DXF is not normally used for 3D, DXF is best for 2D drawings, IGES is for 3D.  Fanuc 6 refers to a g-code format used in Fanuc 6 cnc controls that a CAM system produces code for.

Hi Art,

my chess king is looking more and more like a production part, looking good, keep up the good work.

I have the full set if you need them for testing.

Hi,

G28 x0 y0 z0 sends the machine to a known home position, e.g. the machine has already been homed before.

G28.1 x0 y0 z0 will send the machine to find the home position whether its been there before or not.

General Mach Discussion / Re: G52 with Tool Radius Comp (G41)

Hi Eric,

this is a known bug and is on the fix list, I reported it to Brian a few weeks back, if you recode your tool path without the G41/42's all will be fine.

Ok, here is a bit of code :-

For a lathe to put a 5mm rad on the end of a bar in diameter mode.

G00 X0 Z0 (move to start point)
G03 X10. Z-5. R5. (form rad)
G00 X50. Z50.(rapid away)

I am not sure what you are wanting, can you give more detail on the problem.

Do you have any values other than 1 in the scaling DRO's? (program run page top centre)

Are you working in MM or Inches ?

Have you calibrated your motor tuning ?

If you go to MDI and enter G91 G00 X1. how far dose the table move 1mm or 1 inch or ?

Hi Malcolm,

this is what I get from your code, it looks fine to me.

G-Code, CAD, and CAM discussions / Re: Speed Feed and Depth per pass question

« on: June 10, 2008, 12:05:31 PM »

Hi Robert,

most tooling producers (not all) base there feeds and speeds on a cut depth equal to half the diameter.

If you read the data sheet again you may find it says something like if depth equals diameter half speed and feed, .25 depth increase by 25%

If you look through the forum there are lots of threads on this subject.
