tldr; While I wait for filament to be delivered, I'd like to understand how to change filament and any tips to get more smoothly started in the printing, and any advice on maintenance, cleaning... I've finally completed the commissioning stage, and a couple of minor panics re the belt tensioning, all seems to have gone well. It may seem more than a little remiss, but at this point, I still don't have any actual reels of filament - only the samples sent. Naturally I want to print something as soon as I can do so, but I'd like to ask a couple of details that are missing from the build manual. When you get to the "Your first print" section, it only gives instructions using a reel of filament. I also read in the forums that using the loose filament can be problematic, as it's more likely to snag or jam in the printer. Should I be so concerned? There are other two reasons that make me hold back - that calibrating for such a small sample will be a bit wasteful, and secondly, that I will have to change the filament again before I've had a chance to get used to how it works. Are there any good resources / videos that explain how to change the filament (applicable to the BigBox)? I also, by mistake, ordered some Colorfabb PLA/PHA, which, in retrospect, seems to have mixed reviews, and also has different properties to PLA. I do really want to get used to PLA (I think) at first (and changing between filaments / types), before moving on, so I now asked to change that for the Premium E3D filament. Does anyone know any good videos / tutorials for these basics (including maintenance, cleaning, etc)? Sorry if I'm asking stupid questions - I feel so relieved that so far the printer progress is going well, and I want to keep that momentum going as smoothly as possible. Also, thanks to everyone who's given support and advice thus far. I couldn't have got this far without such an amazing community and fantastic support!
