Trying to set origin coordinates

[LockTech]

I have a piece that is going to require a few manual tool changes, therefore I am wanting to run these as seperate gcodes.

I created a fixture and now I am wanting to clamp an item into that fixture and run several different steps on it using the original alignment I used to produce the fixture. So now I have different layers saved as DXF's and I made a starting point in the same place on each layer. However I dont know how to tell LazyCam to make that starting point a certain X,Y coordinate?

Did all that make sense?

Also, how do I change the direction of a cut? For example I have a straight pocket the same width as the bit. LazyCam is automatically setting it up to run right to left because its closer to the starting point. But, I want it to cut from left to right, is there a way to tell LazyCam to switch the direction?

There's a new manual that may have the info you need.

Thanks Gerry, I will check it out.

Well I scanned through the ebook and a very good book it looks to be. I did find out how to change my starting cut point, so thank you for that.

I was not able to find out how to change the origin coordinates, or should I not do that?

Thanks

I don't use lazyCAM, but you might try moving the drawing in your CAD program so the origin is where you want it when you save the .dxf.

My main use of Lazycam is to produce engraving.

I am having difficulties working out how to center the engraving on the item.
Say for instance, i have a round item that i want to engrave. I do a .dxf drawing, but Lazycam has everything referenced to the bottom left corner. I'd like every layer and chain to be referenced from the center of the engraving....

Thinking of doing some changes to the drawings to make a line or cross in the center... change the layer to 1mm above the work, so that i can stop the program on the line or cross and set the center.....

Anyone can help?
