I finally got around to cutting the project I described in this thread.
All was going good until a little while after switching to a 1/16” bit and I had a shift in X. I wasn’t watching at the time so not sure what happened. It couldn’t have hit anything. The only thing I can think of was too much plastic buildup around the bit leading to lost steps or maybe some issue with the vac line but I have never had an issue with that before.
I paused occasionally to clear the bit but after I noticed the shift I paused to look and there was a a good buildup.
You can see it in the lines to the left of the words.
Naturally I had already messed up the back side because of a brain fart when setting the Y zero. I couldn’t use the BitZero on this one since the material is 36” wide so the corner was out of the cutting area on my Pro XXL.
$80 worth of 1/2” color core wasted. I can use the unmolested area on the back for some smaller projects.
