Temperatures can be manually set in degrees Celsius. If you upgrade your hot end (say, to an all-metal E3D v6 from a PEEK one), you’ll want to be able to increase the maximum temperature so that the printer knows it can go up that high. Knowing how many endstops the printer has and whether the switches are always on or always closed is important, and these settings are easily adjusted here. Setting how many steps is required to move the motor one millimeter is critical for calibrating the printer and making sure it moves correctly. Changing the value for the direction of the motors will cause them to spin the opposite direction. While motor wires can be physically swapped around to change the direction in which the motors turn, the firmware can sometimes more easily be changed.

Defining which thermistor your hot end uses is absolutely necessary to ensure that the temperature is measured correctly. A4988 includes a fixed current regulator close. The product can be in full, half, 1/4, 1/8 and 1/16 step mode operation bipolar stepper motor with an output driving performance up to 35 V and + / - 2 A. This A4988 equipped board is a micro stepper motor driver with a built-in converter. Thermistor typeĭifferent thermistors have different resistances to measure temperature. Build your own 3D Printer with this Motor Driver Module. The type of controller board your printer has. The rate at which bits of data are interchanged between the board and the host computer.
