Hello! im playing around with stepper motors/ dc motor for the first time. i bought this timing belt: GT2 Timing Belt Pulley, 8pcs 5mm 20 Teeth Timing Pulley Wheel and GT2 5 Meters Rubber 2mm Pitch 6mm Wide Timing Belt with Allen Wrench for 3D Printer CNC by Beauty Star https://www.amazon.com/dp/B0776KXY8G i got things connected and running to some degree. But i wasnt able to close the loop properly. I googled, watched youtube.. tried super glue, tried shrinking wrap, just read about threading with nylon . Why is it sooo hard to find resources on how to close the loop? i have a custom length loop Thank you so much. This is my first post here
