The filament run out seems pretty essential to me when prints sometimes run into the early hours and then run out of filament.
Anyway I can cope with it not working, the E2 shows approx the amount of filament left on the reel and seems to err on the safe side. I like the Ideamaker slicer as well, it shows the amount of filament required and the cost of it.

I looked at the Leapfrog in the link, looks a super machine, but it's physically too big and much to heavy for my situation here.

If I do send this E2 back I'll be looking for an alternative with a similar build volume.
I think I looked at the BCN after I sent the Creator 3 back and they were possibly out of stock.

It will certainly be with reluctance if I send the E2 back because it really is a cracking printer, just needs a better support back up.
