3DPS Europe – the mindset behind the workshop

https://www.youtube.com/watch?v=Ykkbt8RgGxI&t=818s When using my large-format 3D printers, getting filament from the dryer to the print head has been a constant struggle. Unfortunately, most machines equipped with lightweight print heads have weak extruder motors, and pulling filament over long distances also generates excessive heat. There are, of course, many solutions available on the market for this problem. However, these solutions do not allow the use of any type of extruder for feeding, and they are limited in terms of distance. They also lack the ability to create a controller separated from the buffer, and they do not learn the consumption rate, which often leads to jams in the printer’s extruder. The extruder I intend to bring to market will have the following features: LOAD function: supports distances up to 10 meters and filament spools up to 10 kg UNLOAD function: tracks the filament length loaded during the LOAD process and can retract it back to the extruder Auto Refill function: automatically feeds the next spool when the current filament runs out 50 mm buffer length Automatic speed adjustment based on filament consumption rate Built-in TMC motor driver and standard 2.54 mm JST connector for the feeder motor Firmware update capability 12V DC operating voltage LED status indication Type-C monitoring interface Firmware- and printer-independent operation (compatible with Marlin, Klipper, RepRap, or any other system) Bowden tube disconnection protection: if any fitting fails and the tube disconnects, the system feeds a maximum of 150 mm of filament, then stops and issues an error signal Alarm output (Pro version) Handling up to 8 filament spools simultaneously — feeding into a single output, multiple printers, or a combination of both Issues resolved so far: Replaced 12V–5V conversion with a DC-DC converter Replaced series resistors (since 82°C is too high for a resistor) Adjusted TMC motor current Changed notification LED position Created a debug tool for component testing Replaced return spring with a stronger one Redesigned filament guide channels for smoother automatic loading Since launching the campaign requires video materials and extensive testing—which reduces the time available for my other work—your support will help make the campaign possible
