I have the same issue

sometimes if I turn my layers on and off, it starts working 

sometimes if I select all operations it comes on, and then works normal for a while

pretty damn annoying 

Good morning

what does locking operations do

I have trouble with speeds and feeds changing

I set all my speeds and feeds in every operation....and then i code and look thru and a few have changed back to default speeds

if I click on a tool in the list in the op window.....or rename the tool all the speeds and feeds settings change sometimes and sometimes the stepovers in cut parameters in dynamic milling ops change also

i have to go thru 3 times each op sometimes to get them to stay

a whole lot of wasted time reviewing and resetting

i have lock feedrates set in config if i open an existiing file that setting is not necessarily checked

So does locking ops have any effect on keeping things set they way i have set them

i use alot of high performance endmills and they have to run at speeds feeds and stepovers that are the manufacturer specifies or they wont warrantee the cutter

Thanks 

you can also go into the post and remove the path call and just keep the file name 

i think its 80 characters max length but not sure
