Re: Is this really backlash ?

I am having a similar issue with 'backlash'.
Here is the file I am cutting from:
And here is the outcome:
You can compare the insanely large varying gap by comparing the red and green circles.
Notice the orange arrow. This indicates typical backlash.
Yet, look at the blue circle. The far left side was last to be cut. This area is grossly lower than where it should be! (compare to vector file above)
So my thinking is this is software/firmware related because, IIRC, this phenomenon did not begin until I upgraded from an older version of LaserCad to the latest with the PPI update. However, I also changed PCs as well. There has been no electro/mechanical changes.
