Filament continuation
I am about to run a large print, but I know there will not be enough filament on the reel, how do I get my XL Original (2 heads) to automatically swap heads when the first reel has run out?

One problem to look out for: The inner end of the filament on some spools was bent sharply into a hole when starting the fill - so in some cases this hooked end catches the spool and tugs the filament tight causing underextrusion and if it does come free the bent end can resist entering the PTFE delivery tube with the same result.
If possible, cut off this bent end, ok, it's tricky when the spool is full so at least try to attend the printer when the filament is low enough to do so.
Cheerio,
