How to cut a print fine…
I’m digging your z-screws and extruder setup. I’ve been riding the same horse for a while and it feels like it’s time to upgrade HW.
Z Screws are the stock Migbot ones, the E3D mount is my design and the extruder is tge stock Migbot one that’s been modified to allow the use of the E3D
Also thanks… should have said that first 
That’ll bring on the anxiety, if you see it happening. But such satisfaction when the print ends!
Now that was an efficient end of that spool.
@Griffin_Paquette - It was a 5-ish meter length that I’d cut from a spool, but I’d had a couiple of rough prints so it was just over 4m by the time this print happened, S3D said it would be just under 4m, so I left it run and that was the result. It was still arse clenching time when it was getting low…
