Dear people,
I am retrofitting an old masterwood project 309 with mach4 and a CSMIO-ip/a. I am at the stage that I can test the machine. I now havea porblem with milling somehting. I use fusion360 to generate the gcode. Below you can see a screenshot of my sketch. The problem I have is that the upper y value between stock edge and the inner rectangle is 100.5mm and the lower value between the edge and rectangle is 99.5. The distance between the inneredges of the rectangle are perfect. It looks like the program takes the whole rectangle and places is 0,5mm lower on the y axis. The stock dimensions are 2310mm x 875mm
When I try to run a other op like a slot the dimensions are perfect and the problem does not occur. Is this maybe a porblem with arc mode or distance mode of some sort? or maybe in my cam skills because they are not great.
I am really desperate because I can't seem to find the problem. I really hope someone could help me with this problem.
