E3Dv6 vs hexagon

[printbus]

...the bore on the hexagon is tight. it will will be more prone to jamming. from what i read its 1.8mm. you have to keep in mind also that plastic expands when it gets hot so 1.75mm filament for example very well might just make it down the bore without a jam. if you hit a spot that is 1.77-1.78 your done for. im not sure why they made it so tight. most hot end bores are 2mm...

This is why I provided the earlier link. I've had multiple rolls of 1.75 PLA with bumps in the 1.80 to 1.90 range. I continue to believe that this is a more common reason for filament "jamming" than people realize. I put an E3Dv6 on the budgetary wish list as soon as I read it could accept filament larger diameter than the hex.
