Is this an all-V-slot design?
Also, I have seen several people not use the relay; is there not a mosfet heater driver as a standard part somewhere?

How is the flex/stiffness of this larger 12" frame?

@milkypostman: Good ideas. Nice thing about aluminum...it heats up and cools off real quick. May have to give that a try.
Also, today I made a huge mod. Dropped the heat bed relay. I was finding that when the bed heater came on (bang-bang style), the first and second layers were messing up big time and getting patterns in them. So, I had some IRF4905 MOSFETs from a different project. I took one of them, and with the aid of a 10k, 1/2 watt resistor and a small heatsink, made a high current switch. The RUMBA board does low side switching and this is perfect for this. The IRF4905 turns on when the gate lead is grounded which makes this such an easy mod. Put the gate lead to the heat bed negative terminal and the middle leg of the device went to the positive side of the heat bed and the right leg went to +12. The 10k resistor is mounted between the outside legs and keeps the device off when not called for. So, turned on PID mode and retuned. So nice not to hear a relay clicking on and off. The next big question is, does the print clean up or not? I am currently using two supplies, one 50 amp supply just for the heat bed and a bank of batteries to run the rest (they were there, so use them). What a day.

Relay controls the bed? I would imagine a non-relay option would be a first upgrade. Or is the cost a big jump?
