There's a lot of good things being said about this printer ...supposed to be blisteringly fast. I'd be interested to hear your experiences with it, as I've been considering upgrading to the 'next level' of printer for a while.

First of three staircases done ...13 separate parts, about 45 hours printing.
I've used these peeps for years (I only print with PLA though). Never had a clog with their stuff, unlike others I've used. They're my go-to now and it's nice that it's made in the UK. Not the cheapest, but consistent.
Hoping you've sorted your problem, but if not, a fella in a F*cebook group I belong too has described a problem similar to yours, although on a Mingda not an Ender. Turns out his problem was a grub screw on one of the extruder gears loosening a bit. I suppose any slipping could be heat induced...

I always open any downloaded files in 3D Builder (built in to my version of Windows) to start with. Just downloaded this and 3d builder had to 'fix' it before it would open it, but it did seem to come out the right size afterwards ...not sure if this is helpful?
