Hello Everyone

Since the beginning of the “Filament Spool Switcher & Winder” project, I have always used a cordless screwdriver. One day I had an idea to create an automatic filament winder using a motor. During the tests, I decided to add the automatic stop function after the filament winding was finished, so that the process would run fully automatically. I created the whole project over a month because I tested a total of 6 motors until I came to the best solution. I lost a lot of time, nerves and money :-). I had to make sure it worked every time. That's why I rewound 25 spools of filament for 2 days. Yes, 25 spools :-) and only for testing. By the time the project was published, I had rewound over 67 spools in total. I am a reliable person. I never post mechanical designs unless they are thoroughly tested. If you follow my recommendations below, you will be guaranteed trouble-free operation. However, if you do it your way, don't blame me that something doesn't work as it should. You make any modifications at your own risk.

Special Thanks to :  
@Shoe  for his contribution and help in this project

When you complete the project, please share a photo and a comment. Thank you and have a nice day.

UPDATE 03.03.2024 : 

• I added separate catalogs for Original Winder Spool Frame by Miklos Kiszely & Remix and Motor Drive 2 - Modular Design for Stand and Update from Winder Spool Frame 1 to Winder Spool Frame 2. Now you can download the selected version for a given project faster and easier - In the photo gallery there are instructions for Winder Spool Frame 2 - Modular Design and Update from Winder Spool Frame 1 to Winder Spool Frame 2 - The other things in the project remain unchanged

UPDATE 10.03.2024 : 

• For the "Original Winder Spool Frame by Miklos Kiszely & Remix" version, I added two new versions of the file: Motor Housing V2.stl and Wires Holder V2. In the case of the Motor Housing V2.stl file, changes only in appearance

UPDATE 11.03.2024 : 

• I have added a new version of "Motor Drive 2 - Modular Design for Stand" intended exclusively for the "Winder Spool Frame 2 - Modular Design" project

UPDATE 12.03.2024 : 

• I have added a new version of the Knob M3 which now uses a Heat Threaded Insert instead of a nut

UPDATE 10.04.2024 : 

• Minor visual changes for the files: Motor Drive 2 - Modular Design - Motor Housing.stl and Motor Drive 2 - Modular Design - Motor Plate.stl

UPDATE 02.05.2024 : 

• I added a new version : Powered by Magnetic Power Bank. The assembly instructions and wiring diagram can be found in the photo gallery. The project is included in the catalog with the MPB designation "Motor Drive 2 - Modular Design for Winder Spool Frame 2 - MPB"
  
  
  

What do you need to do for the project to work properly? :

• Use my remix "Bambu Lab Filament Spool Winder - Upgraded" which provides support for the lower gear axis 50 - Applies only to the first version: "Original Winder Spool Frame by Miklos Kiszely & Remix". The new version of the "Winder Spool Frame 2 - Modular Design" project has a different structure - https://www.printables.com/pl/model/478890-bambu-lab-filament-spool-winder-upgraded
   
• Use my remix "Bambu Lab Filament Spool Winder - Upgraded All Gears and Axes" which includes new gears and hexagonal axles. Be sure to use Axis 32mm - with holes for Heat Threaded Insert M3 - Applies only to the first version: "Original Winder Spool Frame by Miklos Kiszely & Remix". The new version of the "Winder Spool Frame 2 - Modular Design" project has a different structure. -  https://www.printables.com/pl/model/478967-bambu-lab-filament-spool-winder-upgraded-all-gears If you do not want to print all gears, use at least gears 50 bottom, top and Axis 32mm with holes for Heat Threaded Insert M3. Secure them with screws. Bearings without this can pop out of the winder frame.
   
• You need to buy a suitable motor with a minimum torque of 2.5 - 3Nm (25-30 Kg.cm). If you want to rewind spools of filament weighing 1 kg - it must have these parameters !!!. Note that even an ordinary cheap cordless screwdriver has a torque of 14Nm - 30Nm. If you buy a weaker motor, you will have a problem with rewinding a 1kg filament. In motors, the higher the rotational speed, the lower the torque. I tested the motor 150, 200, 330, 400, 550 revolutions. As for me, only 150 rpm is trouble-free. The 330, 400, 550 rpm motor couldn't handle a 1kg spool. If you find an motor with more than 150 revolutions that will have a minimum torque of 2.5-3Nm, you can safely buy it.
   
• Follow all other recommendations and use the components listed below.

IMPORTANT - READ :

• One of the most important things is the perfect fit of the gears in the “Filament Spool Winder”. There must be a slight gap of about 1mm between all gears. Thanks to this motor, it will be easier to rewind the filament. Each additional unnecessary friction on the toothed gears reduces the motor torque and thus the motor power decreases.
   
• Strengthen the Motor Gear 25 using Heat Threaded Insert M3 - 4pcs and Screws M3 16mm - 4pcs. View photo galleries - Applies only to the first version: "Original Winder Spool Frame by Miklos Kiszely & Remix". The new version of the "Winder Spool Frame 2 - Modular Design" project has a different structure
   
• I decided to use the module from the Creality filament sensor because only it has a bearing on the arm. Thanks to this, the filament moves smoothly. In addition, it is complete with wires. For this reason, I decided not to use a standard sensor. I suppose that the arm from the limit switch may heat up at such speeds due to the friction of the filament, which may cause distortion or melting of the filament. So I do not propose to replace my solution with a standard sensor. I realize that not everyone will like using the Creality Filament Sensor. That's why I made a second version for the limit switch. Everyone will have the choice of which version to use. 
  
  DO NOT CONNECT POWER TO THE SENSORS !!! ONLY NEUTRAL WIRES  SHOULD BE CONNECTED TO THE SESNORS. WIRING DIAGRAM IN THE PHOTO GALLERY.
   
• The Filament Sensor can be mounted in two ways. See in the photo gallery.
  Version 1 - Directly at the Filament Guide
  Version 2 - On a long PTFE tube
  If you notice that the tip of the filament loosens after the winding process is completed, use version 2. I use the version 1 and I had no problem with unwinding the filament from the spool. When choosing the version 2, the filament should stay in the PTFE tube. Then you will manually wind the end of the filament onto the spool.
   
• The filament sensor housing has a limiter for the PTFE tube. When assembling, insert the PTFE tube until resistance is felt.
   
• Do not be guided by the technical data of the motor where there is information that the motor with the shaft stopped consumes 5.5A. For all tests, I had the motor connected to my lab power supply. I stopped the shaft several times for 10-15 seconds and the draw was never more than 2.1A. With normal motor operation, it is much smaller. I tested it on the original Pololu and the replacement. Therefore, a 3A power supply is sufficient for the motor and the motor controller. This significantly reduces project costs.
   
• Using the Auto-Stop Function is not necessary.
   
• To install the new version of "Motor Drive 2 - Modular Design for Winder Spool Frame 2 - Powered by Magnetic Power Bank" it is required to have a hexagonal wrench with a ball end or a hexagonal wrench with a very short arm. The installation of the two screws for the "Power Bank Housing - Lower.stl" mounting is difficult.
