Z height issue - CAM/Post Processor/Controller/Mill?

[Dangle_kt]

now the tool pullout sounds possible... Before this op it running some adaptive clearing and I noticed the floor had steps in it, getting progressively deeper I thought it was all part of the same controller issue - but it's quite possible the heavy cut I was doing has dragged the 10mm endmill down within the collet. I seated the tool up against the top of the toolholder, so when I am in from work I can check by lossening it up and seeing if it can be pushed up, if it can then that is my issue.

Thanks for your help - any advice on stopping end mills walk out of collets is welcome :D

Check the recommended torque for the collets you are using and tighten to a significant percentage of it, you might find that 50% of recommended is way more than you're currently using when you do check.

If you are using ER collets, I would suggest looking at the ball-bearing version of the closer nut (available from Arc Euro and probably a bunch of other places) - let's you tighten the nut more easily.

well I went and checked, and you were correct - I had tool pullout. Thanks for the pointer
