The only option on the window is to proceed, and closing the dialog window also has the same effect. I don’t know that there is a typical use case for this, but it forced me to go hit the panic button as I didn’t have a bit loaded and didn’t want it to crash.
Since it’s monitoring the travel, would it have mechanically crashed? Would it have required re-initialization?
I have managed a couple times where I missed the load new file button and accidentally hit load new tool. It was mostly a combo of the small touchscreen and not having the Windows scaling settings proper. But it would be a nice option to have a button to cancel the tool change for those kind of moments. In the end though I usually just have it to touch off anyways, so really it’s just a minor inconvience of a minute.
If you have a feed / hold button you can halt the movement of the router to allow you to install the bit of your choice. Not a cancel operation but you don’t have to start over.
I tested this at the initial reading taken by the system PRIOR to loading a file so there was nothing to click on but pressing the feed / hold button a second time allowed the machine to continue.
