Newbie Alert! Offset problem
« on: August 21, 2007, 02:20:48 PM »
Hi, I'm new to CNC and I'm having a problem setting offsets in Lcam Pro, I've included the files i'm working with. The material is .25" thick the cutter is a .125" endmill. The squares and rectangle need to be cut through and I set an inside offset for cutter compensation using the tool I setup in the tool database for a 1/8 inch cutter with a diameter of .125 in. The outside of the horseshoe should be 8.025 in wide so I use an outside offset using the same tool. The secondary inner arch needs to be cut .125" deep and I used an inner offset on that section. When I cut the part, the dimensions come out wrong it comes out at about 7.75" wide and the squares and rectangle are wrong. What am I doing wrong? Help!!! ???

I have had a look at your DXF files and the problem may be that you have multi lines making up your contour (See Picture).

It is always better to have your DXF files as one continuous single line.

I would try it again with single lines.

What did you use to draw the outline?
