what went wrong

[CLASICOAK]

set this job up, viewed my toolpaths , started the job did the rough cut , changed the bit started the model cut. checked the progress occasionally was going ok. the last time I checked was at the end of model cut just before profile it looked good came back and had this . what could have caused this. the profile cut is off center and there is a cut running down the middle of the job -Jeff [attachment=1]sailboat1.jpg [attachment=1] sailboat1.jpg

First thing that comes to mind is your mill slipped from the collet from either a wore out collet or it not fitting tight. and/or it had a bind somewhere and you lost some steps. I once used a 1/8" collet with a 3mm mill and had that problem.

later on I am going to run it and use the pink foam and see what happens -Jeff

Looks like lost steps to me.

One thing that helps all of us is if you list what type of machine you are running in your profile so it appears over here----------------->
