Vivid isn't worth your time
I've had this unit for 3 months now, it has yet to provide a decent result
Finding stretched nearly torn belts on the filament feed shaft, stripped grub screws on the filament gears and pinched wired in the case feeding the chamber heater. This unit is not worth your money. Inconsistent spool winding sometimes it works sometimes you end up with a ton of filament inside the machine not nearly spooled back on the roll.
Latest failure, to feed. The idlers tight the cam rotated the filament is snug in the tube but it does not feed.
This is the worst product btt has released it needed more time to figure out how to actually work.
Initial setup was impossible had to switch to happy hare as the btt automatic installer wouldn't complete with no clue as to why.
