I'm now on my second ramps board due to the pt100 shorting out components. I followed ythe instructions that I had found on Rerap's forum but it still shorted out. Any advice would be nice
I have a PT100 on my Prusa i3, which uses a RAMPS 1.4 board. I've had no trouble with it at all other than when I messed up - see below. I followed the instructions here http://wiki.e3d-online.com/wiki/E3D_PT100_Amplifier_Documentation to attach the PT100 using e3d's PT100 amplifier board. Make sure you edit pins.h as stated though, I flashed the firmware with an unchanged pins.h once and spent ages working out why it didn't work.
