Loading filament annoyance
Does anyone have any tips for this?
If I want to load filament in and the nozzle is in its start position (very close to the bed), this means that the filament gets caught between the nozzle and bed and turns into a big-ish blob.
I have to calibrate Z so that the nozzle rises and I can clean the nozzle.
How can I sort it so the nozzle moves up when loading filament?

Re: Loading filament annoyance
The easiest way is to use Long Press of knob. This will trigger Z-adjust shortcut where you can do so at any time. Best not to tempt fate by using during print though. I also use home rolled G-code. I have one for each filament type I use. Maybe you can mod to your liking.
Below code is for PLA. Also please note, I have extruder setting code in there. You can comment out or use your own settings.
As always, use at your own risk.

Script error. Confused extruder relative with positional relative. Corrected below.
