very useful thing. It has been working for me for 5 days on the Ender 5 Max. I passed about 3 kg of filament through myself. + in that it helps the extruder (it pushes the filament forward with its motor) + no longer need to monitor the change of the spool; it will automatically change when the thread runs out. just need to set the time interval for refilling the additional thread (choose from 3 options) For proper operation, I needed to glue PTFE at the entrance to the extruder. because periodically the tube would be torn out and the buffer would provide an unrestricted flow. I bought a new fitting with a clamp, but it hasn't arrived yet. printed holders for 2 reels I secured the tube with electrical tape. Without fixing it to the buffer, there were interruptions and as a result, printing was interrupted. The moving part must always move forward and downward parallel to the guide rail. Good luck to everyone!
Works as expected according to the instructions.
Main filament goes in the left port, backup spool on the right.
Manual load and unload buttons work without any issues.
I replaced the filament runout sensor on my Ender 3 V3 Plus with this system, which in any case works better than the original.
Works well. I already own three of them, and all my printers are equipped with this device.
Be patient with it, it does work.
Very good product, comes with clear and good instructions. So far it's working great.
Great device. Works independently, so it is compatible with almost any printer. Especially useful when the filament spool is placed far from the printer.
improves the printing, less stress on the extruder. Very happy with product. great when printing large prints that require more than a kilo, it loads automatically the second filament. would recommend
