cutting motor control board

There are 3 cutting motors on the RL2000, there is no real need to control these independently, therefore they will be driven from a shared output. The temperature of the motors should, however, be monitored independently. The motors have in built thermistors, therefore can be monitored using a resistor ladder with the analogue inputs to the arduino.

connector block

I’ve decided to change the design to be more modular, this will allow me to develop the system incrementally, as such I will use a set of stackable boards each board having there own function.

The “top” board will contain the connectors to all of the sensors/drivers (also containing the main pi zero) as shown in the diagram
