1.7mm filament

[alaris2 1]

it's cheaper and easier to buy 1.7mm filament here - so I wondered, if I change the bowden tube to a smaller ID.. is there any other reason why I can't print with 1.7mm filament?

I guess you would also have to replace the brass tube of the hot end to match the filament's diameter.

And its quite possible that the range of adjustment for the feeder isn't quite large enough to adjust for 1.7mm filament.

You'd want something like a 2mm ID tube. But that's unlikely to be 6mm outer diameter. So you'll get 4mm. Next you'll have to change the clamps everywhere.

I'd say internet-order your filament well in advance so that you have it on time.
