Relay Fix for DC Extruder Motor Thing-O-Matic

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
