After a few months owning the FLSUN Q5 printer, I only recently obtained acceptable results with ABS.

ABS is notoriously more difficult to manage than PLA and my first attempts with left overs filaments from an old 3D pen have all been disappointing, no matter the print bed and nozzle temperatures or even the speed.

I eventually gave up until I ordered, by mistake, a big 1kg reel of ABS instead of PLA! 

I had no choice but try to make the best out of it...
