Re-home after filament change? [feature request??]
Ran into an issue today after a filament run-out. The tool advanced to the front of the bed as expected after the filament sensor triggered due to running out of filament. However, the filament did not eject properly [more on that below]. I needed to open the tensioner, remove the tftpe tube from the top of the tool and pull the filament out [more on that below as well].
Anyway, in the process of doing all of that, I must have moved the print head slightly as when I did get the filament reloaded and the print resumed, it was off less than 0.5mm, but off none-the-less. Fixing the physical issue with the failed ejection is of course the best thing, but since this happened, my question is, can the XL [or any of the models really] automatically re-home on the x-y after a filament change so in case there was any movement it corrects itself and doesn't ruin the print? This was 'only' a 10-hour print, and it was 94% complete when the filament ran out, and thankfully wasn't critical that it be without blemishes, so it isn't the end of the world this time, but I can see it being an issue in the future.
I know a z-axis re-home would be a logistical nightmare, but I'd think the x-y axis' should be straight forward and not take more than an extra 30-seconds. A fair trade-off in my opinion.
Now, as for the failed ejection, what happened was the filament got stuck inside the filament sensor on the side of the unit. No doubt got pulled in past the guide tube and then got stuck there when it couldn't slide back into the guide tube to eject. I haven't yet opened the filament sensor to see how this might be fixed to prevent the issue in the first place, so any insight into this would be appreciated as well.
