GT2 PULLEYS - 8mm Bore -  20 Teeth - RepRap Prusa Mendel etc

Aluminum 20teeth GT2 Timing pulleyBore8mm
20-2GT-6 BF Fit For Reprap 3D printer Prusa i3 mendel

20 Teeth GT2 Timing pulley Features:

The GT2 pulley with 20 teeth or grooves is one of the best choices for 3d printer construction. Compared with the T2.5 or MXL timing pulley, the GT2 pulley tooth profile is anti-backlash.   The rounded teeth of this tooth and belt are engaged together longer providing a smoother transition between teeth.

  Warning
  Make sure the power supply voltage dose not exceed the drive’s input range. Double check the connections and make sure the power lead polarity is correct.
  Do not set high current to small stepper motor. It is possible that the motor will be damaged.
  Disconnect the motor from the load if you are not sure the move direction. Adjust the axis in the middle before trying to run the motor.
  Never disconnect the motor lead when the power source is energized.

3D Printer Controller Board Module For RAMPS 1.4 REPRAP PRUSA MENDEL New

Brand new and high quality. RAMPS 1.4: RepRap Arduino Mega Pololu Shield 1.4 Fully assembled & tested It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Version 1.4 uses surface mount capacitors and resistors to further cover edge issue cases. As of version 1.3 in order to fit more stuff RAMPS is no longer designed for easy circuit home etching. If you want to etch your own PCB either get version 1.25 or Generation_7_Electronics. Version 1.25 and earlier are "1.5 layer" designed boards (i.e. it's double sided board, but one of layers can easily be replaced with wire-jumpers) that is printable on your RepRap with the etch resist pen method, or home fabbed with toner transfer. This board is mostly based on Adrian's Pololu_Electronics and work by Tonok. Copper etch resists methods suggested by Vik. Also inspired by Vik's work with EasyDrivers. circuit design based mostly on Adrian's Pololu_Electronics Joaz at RepRapSource.com supplied initial pin definitions and many design improvements. Much inspiration, suggestions, and ideas from Prusajr, Kliment, Maxbots, Rick, and many others in the RepRap community. Size: 11.5cm x 6cm / approx. 4.5in x 2.4in. Package: 1 x Printer Controller for RAMPS 1.4
