Re: need some help. again
hi. ok this is what I am getting. I have set the home position and machine G54 homing position to zero. the home position is with the machine bed 70 percent into the -x travel and the y at mid point of its travel. the z homing position is just at the start of its downward travel. the machine position G54 is with the x at 50 percent into its travel so at midpoint and the y axis the same and the z just in contact with the work surface. I am not sure if this is correct or if there is a better g54 position to use.
ok I made a drawing in solidworks, exported it into artcam and this is the program it made.
Tool No1.

this program is just a test for a .5mm deep slot. what worries me is that there looks like there is know start position. ie g54 position.
I tried it on the mill a small MF70 and the tooling went all over the place.
what am I doing wrong ???????????

Re: need some help. again
To get back to your original request, I drew a small oval given the sizes you specified
Quote:
Any small shape would do a oval around 40mmx10mm 3mm deep would be good
The dxf was then put into Cambam and this is the resulting code :-
0,0 would be set right in the centre of the oval, and Z0 would be the top of your part, it is set to go down at .5 depth of cut, so for a total depth of 3mm, should go around 6 times.
Give it a try and see if it works?

It might be better to attach the file rather than post the code as you can see it takes a lot of space
Re: need some help. again
Terry It is going all over the place because you have not specified G54 at the top of the code.
