Looking forward to that screenshot.

even with 2 amp, i have to use this very thick wire... and barely made it to the crimp that i got from spare computer part.

I will try to take a screen shot next time i use it.

I found a nichrome wire calculator and told it the lengths I was going to use.  I want to make a similar power level to the QU-BD silicone bed.

must be a very low gage nichrome wire right? :-( good luck with that.

2 amp is more like it... (also that's why i didn't do the by pass mod)

So instead of being a 100% concern, its down to say an 80% concern.

Also, do you know of how much current the solidoodle board can handle before needing an external switching mosfet?

Also, what on earth that thermal insulation they use is called..  the white patchy stuff on the bottom of the bed.
