This Timing Pulley has 10 teeth. it is made of Aluminium with a set screw for attachment. Bore diameter is 5mm. It has 2 flanges (dia 20mm) suiting a belt width up to 6mm. Overall length is 17mm.
Stepper Motor Driver Board - DM542A
The DM542A is a type of two-phase hybrid stepping motor driver for one motor. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current.
Input Voltage: 18VDC to 50VDC.
Input Power: <4A up to 80W
Output Current: 1A - 4.2A(peak)
Inputs and Outputs are opto-isolated.
Overvoltage, under voltage, overcorrect, phase short circuit protection
Operating Temperature: -10 to 45 degreesC
15 channel subdivision and automatic idle-current reduction. 8 channels output phase current setting
Replaces the older MD542 Driver
Timing Pulley - XL pitch, 12 teeth
This pulley is made of fibergrass reinforced polycarbonate. It no longer has an Aluminium Hub with a set screw for attachment. It has a single flange and suits belts up to 9.5mm wide. Overall length is 20.64mm Flange Diameter is 25.1, hub diameter 12.7mm, with a 4.763mm bore to suit our Nema17 stepper motors.
T5 belt is not compatible with this pulley - see T5 pulleys
40 x 40mm Heat Sink, drilled for extruder cooling
This heatsink (40x 40 x 11mm high) is designed to fit on the back of a Nema 17 stepper motor, or the front of a Nema 17 based extruder as found on the Makerbot Replicator Series or MBot Cube.
Mounting Holes are 3.2mm diameter, 31mm apart. The center hole is aprox 12mm diameter
