Will the printer main board handle the current draw of the QU BD silicone heat bed?

Re: QU BD

no or not recommended, and the power supply definitely wont

Theres plenty of threads covering this one already, so have a search around for the details - the solutions depend entirely on which controller board you have (depends when your SD shipped).

Re: QU BD

Works with sanguinololu but you have to wire it differently and have the right sized power supply.  I believe I had the negative wired to the hole in the MOSFET to compensate for the small traces on that board.

Re: QU BD

In case you (or future readers) have a printrboard, the supply trace is big enough and the gate driver can handle 100 Amps.

But again, the limiting factor is the power supply only putting out 12.5 Amps total for the entire printer. The Qu-bd heater takes 11.5 Amps.
