 In the case of both the Big MOSFETS pair, and the Small MOSFETS pair, you take power from the PSU to them via their respective power input connectors. ​ In the case of both the Big MOSFETS pair, and the Small MOSFETS pair, you take power from the PSU to them via their respective power input connectors. ​
  
-There is an alternative however. For each pair, you can use jumpers ( one jumper for the small MOSFETS pair ( **JP28** ), two parralel ​jumpers for the two big MOSFETS pair ( **JP11** and **JP27** ) ). If you solder the pins for those OR connect a [[http://​www.computerhope.com/​jargon/​j/​jumper.htm|jumper]] to those pins, closing the circuit to VBB ( the stepper motors power input ), allowing you to take the power from those MOSFETS from the same place as the stepper motors do. +There is an alternative however.

 In the case of the big MOSFETS, you have to solder and put in place two jumpers, in parallel, in order to handle more current. ​ In the case of the big MOSFETS, you have to solder and put in place two jumpers, in parallel, in order to handle more current. ​
