Controlling Stepper Motors

The X, Y and Z axis stepper motors are powered by two Allegro A3959 Full Bridge PWM Motor Drivers, one for each of the two coils in the stepper motors.

The inputs for each of the stepper motors can be found on PDB connector J13. Each axis contains the following individual connections: Phase A, Phase B & Voltage Reference A, Voltage Reference B. Additionally all motor drivers can be put to sleep simultaneously though J13 Pin #45.

Controlling Servo Extruder Motor

The servo motor for the filament extruder is controlled with an STMicroelectronics L298P Dual Full Bridge Motor Driver. This is a DC powered motor with a built in quadrature encoder that sends a signal back for computation of the current position. The inputs for the servo motor are found on PDB Connector J13. There are two input pins for Phase A & Phase B, as well as two outputs to be read from the quadrature motor encoder. Additionally all motor drivers can be put to sleep simultaneously though J13 Pin #45.

I/O Board

The I/O Board is the main place where connections are made to the ancillary boards in the extrusion head, X, Y motors, limit switches and front panel display. It is also where the main chamber's thermocouple is connected along with an on board analog-to-digital converter.
