Thanks ! and so easy to build...

follow the hackadays' link, you will see how easy it is to make one. Please don't forget to like and follow on hackaday :-)

And a part of your firmware is included ==> thanks !

Hello, Oui j'y arrive. Voir ici : hackaday.io/project/185196/log/206126-fusing-two-filaments-into-a-longer-one Mais c'est assez fastidieux du coup je ne le fais plus et je préfère un détecteur de fin de filament hackaday.io/project/185196/log/208440-adding-a-filament-run-out-sensor Merci de liker et de suivre le projet sur hackaday (je suis en finale du concours ) !

Merci ! Non je ne pense pas qu'il existe de solution commerciale. ça s'adresse surtout à des bricoleurs ! Mais pourquoi pas finalement !

Hi, No there is no need for a filament diameter sensor. I do use a wiper motor driven on the low speed and with 5V DC supply. The speed is really smooth and doesn't need any regulation not electronics.

be sure not to increase the output hole more than 1.5mm then try to shorten the lenght of this 1.5mm drill on the "big side" with the 2mm drill and above. The 1.5mm lenght should be 1mm almost. If bigger the filament will force and break. I pull my filament at 200°C and it works. The only critical part is the 1.5mm hole length. Ty severa times carefully not to increase the 1.5mm diam at the output

@@freedom2000 good ideea, I have also optimized the conical surface with a conical mill now there are no steps, I have seen people extrude even at 240C, I have increased the hole tho, to 1.7mm, It will be no problem because I also have a filament diameter sensor which will speed up the stepper if the diameter increases too much, I'm trying to make it as efficient as possible and to not load the motor too much, will test everything in a few days

@@freedom2000 my nozzle keeps getting stuck I can't even pull the filament with pliers, I have tried 210 up to 260 degrees, the pet strip turns white and becomes rigid, It slides for 10-20 cm or so and then it gets stuck again, could this be caused by a too thick strip? 0.6mm thick and 6mm wide

@@alf3071 my bottles are .4mm thick. And my ribbon around 8 to 9mm width. I never go above 210°C as setpoint for the PID. If your filament goes white and rigid it is merlting and cristalyze ... it's way too hot !

@@freedom2000 the bottle thickness was the problem, thinner strips slide better, this bottle started thicker and went thinner towards the neck of the bottle, I need to find bottles with more constant thickness, and a better way to cut them since now I did it with the cutter blade method

Tu peux le faire 1.8mm ou alors 1.75mm diamètre.

with a hole at 1.5mm the filament takes the "perfect" size of 1.75mm

Merci :-)

@@freedom2000 j'aurais juste une question, tu aurais le plan pour découper le bouteille en lamelles ? Merci !

@@freedom2000 Super !! Merci !!
