Easel GCode part scale issue

I calibrated using universal GCode sender, I accidentally flashed my Arduino so had to re flash it following instructions. When I use universal GCode sender and do x300 it moves 300 but when I cut a square that’s 300x300 in easel it comes out at about 32x32 approx.

Help

Thanks Marc jeeves

Yes I did several times, but there is no where to assign a delta what I asked it to cut compared with what it actually cut

Ok I made a nube mistake I thought my path was on the contour edge of the part but it was spiraling from inside to out so it looked really small.
