Hello,

I have drawn up a .dxf file...

Opened it in lazycam... it shows the profile and puts a rectangle around it...

I choose a tool... make sure everything is set... set it to "outside" cutting... but when it posts the g-code it basically cuts on the line.....

How do you make it cut outside the profile....

Do i have to draw a rectangle around the part and then in lazycam remove one complete entity?

Or do i have to draw the item larger as if i'm imagining the cutter toolpath with offset in mind?

Hope you can help

MotoGems,
Consult  the LazyCam manual, Tutorial #5.

Frankly, i would suggest using LazyTurn.

It is available from the Downloads link above and the most current manual can be found in Members Docs.

The part is being cut on a milling machine... so i was using the mill...

In the lazycam manual is shows where the offset instruction is to

"select a chain and press the offset button, this will offset (kerf) the boundary to the distance.... yada yada yada..

Problem is it shows the little box that is on the left of the lazycam offset screen with a create offset button....

When i click the offset button i have

Pro demo. No GCode

button... on the offset and the same in the pockets tab....

the version of lazycam is version 3.00.2

Is this something wrong with that version?

Do i have to download something else?

You need to have a licensed Pro version for advanced features of LC to post code for  ie; offsets, pocketing , lathe etc

I have a licensed version of Mach 3... i guess that's different?

I'll try to find this "licensed Pro version"..... of lazycam...

Cheers

Top of this page...under PURCHASE.

The free edition of LazyCam that is included with Mach3 carries no cost.  However, there is an optional PRO level upgrade that turns on advanced features such as object offsetting, pocketing, primary foam functions, importation of DXF profiles for conversion to Lathe turning code, etc.  It is optional, but gives one the ability to do more advanced importation of objects.  Due to the availability of other low cost CAM packages, LazyCam is in semi-permanent Beta and no longer being actively developed. LazyCam is not intended for use in a production environment.

You need to purchase the license for the pro upgrade....

RICH

OK,
Purchased the pro upgrade....

I guess it will arrive in the next 24 hours..

I'll let you know how i go.

Thanks

MotoGems.

Yes, everything now works fine....

Can offset and do a couple of other things..

Thanks for your help

Hello Rich,

my name is Bob and I'm a total noob to Mach3 and Lazycam and just proceeded to my first test cut just now.
I guess I have the same kind of problem :
I own a small cnc and tried to cut a piece with 2.5 and 4mm holes in it.
I created a DXF that was imported in Lazycam.
I selected the layer and applied a tool with a diameter of 1.2mm and then exported the Gcode to Mach3.
The holes are larger by the size of the tool, and the piece is smaller by the same size (1.2mm) so it's obvious the mill cut on the line.
What did I do wrong?

Thanks for your help,
Bob

PS : I'm french so the manual is sometimes difficult to follow when it gets a bit too technical.
