Printer to replace Z18

[Magicolor]

Mankati Fullscale XT Plus is OK for NinjaFlex, but do not print with a high speed over 70 mm/s, or else, the thick melt filament will make the flexible filament curve in the filament tube,
this kind of problem also happens in some direct style extruder system, the flexible filament curves at the area under the feeder gear.

And I don't think NinjaFlex is the best choice of flexible filament, I found PolyMaker's PolyFlex is a better option for bowden style extruder, because its higher tenacity.
