Axial Cooling Fan for 3D PR...View Instructable »
Hello. Another 10 days of printing with my RCServo extruder. I have printed at least 8 hours/day, every day and all worked well. The longest single printed parts took about 6 hours. So for now is it fine. All printing was done at 60 mm/sec, with PLA and PETG.

Wow, you are fast. Please give us some detail. The new attiny85 based extruder have adjustable current limiting. Also aggressive P.I.D. settings could damage the motor. Thank you for your feedback.
The new version with Attiny85 it is also simpler and smaller. Cheaper and handsome to. I will post it after I finishing the tests.
Thank you for your comments. A small DC motor need gearbox, a large one it is heavy, so the servo was the choice. Also, a good servo is reliable and available everywhere. For now I have about 50 hours with 4 hour the longest print. We see.
