PETG filament is a close cousin to PET (Polyethylene terephthalate) filament. It's the perfect filament to combine strength and flexibility.

• PETG filament has minimal shrinkage and warping
• The filament has easy adhesion, so it can be printed on acrylic, glass, polyimide (Kapton) tape, blue tape, and others
• Has good flexible strength more than ABS filament
• It has great chemical resistance with good acidic and alkalic resistance
• Environmentally friendly and recyclable

• Drive mode: Chopping wave constant current drive.
• Two-phase stepper motor with 4-wire, it is available for rotation of forward and reverse.
• The order of power is AB-BC-CD-DA, from shaft end see C.W.
• Rated current (one-phase): 1.5A DC.
• Rated voltage: 3.45V
• Stepping angle: 1.8°
• Comes with 1m length cable, works great for your DIY projects.

• High torque motor for 3D printer and CNC
• Precisely machined full metal body
• High-quality black powder paint
• Minimized heat gain for continuous run
• "D" shaft for easy and secure coupler connection

This bipolar Nema 23 stepper motor is the most popular and it's
1.8 degree step angle (200 steps/rev). Each stage
Consumes 2.8A, allowing 1.9Nm (267.7oz.in) of holding torque.
