I have a feeling this revolves around the Z offset that is established in the setup wizard. On the picture, the collet nut does not have tapers on the bottom, but in real life you obviously do. My guess is that I need to set the Z to the height of the flats on the collet nut, but I’m setting the bottom of the whole collet assembly to be flush with the top of the pocket/cartridge.
Anyway, check out the video and let me know what you think. It sounds really bad in person and it does it on every pocket with different tools even. At one point it caused my spindle to start making noise so I stopped it. Fortunately after running the spindle for a few seconds the noise in the spindle went away…
I don’t own or use this type of tool changer, but have been interested in it enough to have done a fair bit of online research, as well as reached out to Onefinity and Don at RapidChange ATC.
Firstly, the Redline HMI Realtime CNC software wizard if used correctly will properly measure all the required offsets needed for the successful loading and unloading of tools. Don’s hardware and software take into account the design of the standard collet nut, and so does the Easy ATC/Realtime implementation (software setup steps vary). I would not advise altering any offsets unless instructed - official manual or Onefinity support.
As for the sound, I do not hear the rubbing sound of any misaligned pockets. The load/unload sounds are what I have come to expect having watched many videos over the last few years - both official and those shared in forums like you have done.
I am sure others with first hand experience will join the discussion and share their thoughts and insights.
In all of the videos I’ve seen, there seems to be just a nice little “clunk” - where what I feel like I’m hearing is the bottom rounded parts of the collet nut spinning on the ball bearing detents inside.
You’ve got me wondering if this is just normal though
It definitely kicked something in my spindle out of whack and I’m afraid it is going to cause some damage if I don’t have it set up correctly somehow.
I would reach out to Onefinity. The wizard works, but if for example you selected the incorrect Easy ATC Version, then the offset will likely be off and therefore the nut engagement too high or low.
Support would likely ask to go over your settings and setup.
Dude I’m almost positive that feed rate was 100% the issue - thank you so much!
Why they haven’t patched that in the firmware is beyond me. I would have never seen that post. It is WAY better with the feed rate set higher!
