(work) Arduino stepper motor control box

stepper-motor-control-box

A simple UART-controlled stepper motor driver.

UART configuration

UART is currently configured for 115200 baud, 8N1.

Usage

Send one of start ###, speed ### or stop where ### is the rotational speed of the motor. As the DM556 stepper driver is currently configured for 400 steps/rev the RPM value is effectively halved i.e. 20 set rpm is equivalent to 10 motor rpm.

Wiring

Two 4-pin GX12 style connectors provide motor and heater connections. The pinouts are as follows:

Heater connector

Pin number	Function
1	Heater +
2	Heater -
3	PT100
4	PT100

Motor connector

Pin number	Function
1	A+
2	A-
3	B+
4	B-

Firmware compilation

Board type should be Arduino Uno

Necessary libraries

• AccelStepper
• CommandParser
