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.

[thesaent14]

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

manny

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.

[thesaent14]

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

[ger21]

Z+ should move up and Z- should move down. It sounds like you may have it backwards.

[thesaent14]

wow problem solve lol now how i fixit it is backw how the x and y are suppost to go lol wow i am so stupit well it happents when you a newbe

[KKutt]

Like Ger said, try programming the highest part of the work piece at Z.0 then you can easily see if your rapid positions are violating your part. Don't get discouraged, this is all normal in the world of programming, not uncommon to send an end mill right into tour table! Just try not to! You will get through it. One thing you can do is hit feed hold at the point that the tool is violating the part and read the program line, then you will at least have an Idea where to look for the problem. Trust me it is something simple and when you figure it out... you are gonna slap yourself in the forehead and say &^&*^$&&$&%$
Hope this helps.

[KKutt]

guess I was a little late on that one.. Good job Ger

[thesaent14]

well z axis the + go dow and the - go up what the x and y should do

[KKutt]

The way I think of it is : in and out is the Y axis (just like sex.. in is positive!!!) the X axis is then to you left and right.... and Right is positive. That work for you?

[mar999]

sounds like somthing set wrong in the driver because line 50 of the code says

N50 G1 Z6.3000 F3.20 should be going other way OOPPPS SORRY ger21 already answered this
