Meddeling with Mendel

Its been nearly a year and a half since I last posted about my Reprap Mendel.  I haven’t actually made any progress building it either! This is because I got side tracked with other things including developing RapCAD
Well recently I have taken interest again and started meddling with my Mendel. The first outstanding task was to solder the voltage reg and capacitor to the motherboard. I didn’t much like the official reprap solution of powering the motherboard entirely via the usb port! so rather than add a jump wire between the comms port and the 5v track I instead used a spare track to connect a power connector at J4. This still leaves J1 J2 and J3 to be used for additional extruder’s.
The motherboard will be powered instead from my previously hacked ATX power supply which will provide 0v 5v and 12v via the XLR connections. For some reason the official reprap uses these 3 wire connectors as well but doesn’t utilise the third wire.
