Whatever units you draw your part with in your CAD program is what LazyCAM should use. Set the cutting depth to a negative number, -.25 to cut 1/4" deep. Before running the code, set the top of your part to be Z = 0.

well thats most of my confecion i was drawing in inch and still go dip

[ger21]

Can you post your .dxf file?

[thesaent14]

here it is

[ger21]

Do you have it figured out now? Your drawing is in inches, so you enter the info in LazyCAM in inches

[thesaent14]

so many Q? not know how to make them i do it in inc or mm i don't know why still doing it i don't know whats wrong with my machine i saw the videos on the mach3 web page and i have all the setups like is supposed to be and still do the same is there a way i can speak to some one and see what i am doing wrong


thanks for the replays

Might check to see if your clearance height is set in negative instead of positive or Vise-versa. Just a guess. looks like you are raipiding to a Z 0 then machining above that.

thats somting ells i don't know whats what on this + or - i don't know how the machine is suppost to be
