Do a search on “bitsetter”, “tool change” or “bit change” and you’ll see a couple of dozen topics asking for the same. Yes, I know this thread e.g. **which shows excellently** what you can do if you simply make use of inserting g code into the “tool change” text area input field in the [General Configuration Tab](https://buildbotics.com/manual-v1-1/#generaltab) of the Onefinity Controller: [BitSetter in the future?](https://forum.onefinitycnc.com/t/bitsetter-in-the-future/412/14) But do you see [in the video](https://forum.onefinitycnc.com/t/bitsetter-in-the-future/412/15), **it probes tool length at a repeatable and workpiece-independent position**. If you accept this, **you can run program files with multiple tools right now** with the Onefinity CNC very well today. --- _[View the full topic](https://forum.onefinitycnc.com/t/like-many-new-forums-the-excitement-and/9209)._
