 +==== Issues ==== 
 +  * Printer sometimes doesn't wait until desired temperature is reached. 
 +  * After stopping the print (Kill function), **reset Z-zero** 
 +  * It seems that Repetrel doesn't do accelerations? Why is that?

 +==== Random knowledge ====

 +    * **Reset**: will reboot the 407 motion controller 
 +    * **Aux**: will toggle a relay, which can be used to allow or deny power to an auxiliary item like an air filter or heater 
 +    * **Respond**: was intended to be used to resume after a pause, but I don't know if it's enabled yet 
 +  * If you hear tics in a regular or random pattern, chances are you're printing with 'Spiral mode' selected. The tics are generated by the the Z-axis motor.
