Unfortunately not. I just have not had time to mess around. Ive just marked that machine in the same batch as the Trex2+, ones that you expect to handle anything but no flexible. I mostly have it dedicated to abrasive stuff now.
The only way it could be fixed is reprinting the bracket with the clearance tighter between the drive gear and the feed tube. Simply a design flaw unfortunately. Im not a bug fan of either the lulzbot or itworks aerostruders. They grind almost as much filament as they push. The lulzbot one cant handle 80% fan at 215 for pla without thermal runaway from overcooling the nozzle. The itworks is lighter, and overall seems to be better than the lulzbot design by a small margin. The option to customize it from them is a big plus as well. Not good enough id say I recommend it though. Even the stock bowden extruder on my CR10S5 that I stuck a volcano on seems to keep up better.
