I must be scaling it bringing it into sheetcam. Everything works, but it is 2 times the size I need. How do I use scale in S-cam???

When you bring in the drawing you will have the option as to HOW you want it brought in from a drawing options page. Select INCH and it will bring it in at 1:1 in inches.

Once in you can measure the drawing objects in Scam.

IF it is still not to scale then yoour problem lies in the original drawing.

Post the drawing and we can check it.

Thanks

I can't open your version of the dwg here can you do it in say V14 or a DXF.

It is a vent for a charcoal grill. Thanks

The drawing looks OK and it camed out correctly with Scam.

Does your machine MOVE the exact distance it is programmed to ? Are you certain that MACH3 scaling has not been turn on?

I have redrawn this thing 5 times and it does the same thing. Where would I find Mach3 scaling? Thanks for looking @ it.

Look to the RH side of  the xy dros and see IF there is a yellow led lit up beside each dro.

Have you tested the accuracy of the axis moves?  If you command a move of 5 inches does it move 5 inches ?

Can you post an example of your Gcode that cuts it X2 in size?

Trying to figure how how to post the G-code now.
