 <p>I plan to map the other controller card connections to RJ45 too.
 Will try to keep power on pin 1 and ground on pin 2, and put control
 signals on the rest.  One sad issue is that the print head controllers
-(DC motor, PWM and temerature) in total uses 9 pins - one to many for
+(DC motor, PWM and themerature) in total uses 9 pins - one to many for
 the RJ45. :( Guess I will have to find another connector for these.  I
 will have to keep an eye on the plans to make print heads
 hot-swapable, and see what kind of connector will be used there.
 
+I decided to use one connector for the DC motor controller, and one
+for the PWM and temperature controller.  Here is the DC motor
+controller pinout.  Decided to keep the directions in one pair and the
+PWM signals in another pair.
