Left bias CNC not cutting full contour

Anonymous

I am machining a very simple piece, just a rectangle with a chamfer and fillets around the perimeter. However, every time I start machining the workpiece the offset is biased towards the left. As in the X+ side gets machined and the X- does not. The WCS is centered and the work is probed on center. I was able to get the X- side machined but only after moving my g54 x offset over .035 in  the X + axis direction. I have used cam on a previous job with good success. but this however is baffling me. The Stock setup is Mode: from solid, Stock Solid: body, is selected. 

 

Thank you for any help

It sounds to me like your WCS point in Fusion is not set to the same point as it is at the machine. Can you share your file?
Right click on the file in the Data Panel and select "Share Public Link". Paste that link here if you could. Otherwise, you can PM me the link

Your g-code is perfectly centered in the model and you are going to equal positive and negative values all around (X and Y). The issue does not lie in Fusion.

How are you locating the part at the machine, is your probe calibrated, are you setting the proper offset, is there any XY shift in the common offset?

The part is located on a fixture plate, it is super glued down because I am only taking a light cut. The part is indicated square in X and Y. I probe using an X web and Y web, in the haas control IPS probe commands. I have not shifted the offsets, tool offsets are set. I'll try calibrating the probe again, and probably just probe all sides individually. See if that helps.

Problem solved, I wasnt probing correctly. I overlooked a probing strategy in the control. However I had to adjust the "stock to leave," and enter a negative number -.0980" to get the part finished. 

 

Thanks for the help
