Different wiring of the relays removes risk of shorting the power supply, so no need for diodes to motor, but I added a resistance of 8 Ohms as additional security (in case the motor decides to short internally, probably not necessary). Also, there are no capacitors, because they might influence reaction speed of relays. I did the schematics with "fritzing", somehow they don't look as fancy and understandable as other schematics seen around here. What software do you use to draw schematics (on a mac) ? This absolutely solved the erratic bahaviour of the DC Extruder Motor, who is now ready to print correctly the parts for a stepper extruder. :-)
