X axis profiling positioning out??? Please help.
« on: June 24, 2011, 03:27:11 AM »
Hello

I've just bought a proxxon mf-70 cnc mill and I'm have problem with profiling positioning on the x axis.

The problem is the the pockets with arcs in the body of the part are .2mm's out to the outside profile of the body?
Y axis is fine (symmetrical) but again out .2mm's in the x axis (where it should be symmetrical)

I calibrated the axis, there's no back lash in x and y.

Also if I make the pockets square without any arcs in there it comes out fine??
So I'm assuming it's a problem arcs??
The pocket sizes and distantance from each other are fine again 0.2mm's out in x+ ???
The part is a test piece 20x20 square with pockets in each of it's corners leaving a wall thinkness of 1mm.

Hope some one can help.

Hello and thank you for replying.

I have just this miniute figured out what it is.
In my CADCAM i had programmed it to do the outer body with tool comp.
The post processor for it had not put the g-code in to allow compensation!

Feel a bit silly now! Ha ha!

Again thank you for reply to help.

Much appreciated.
