I read all the documentation I could find regarding wiring the E3D PT100 and it’s amplifier board to the Smoothieboard 5xC, however I found mixed information and want to get some help on the topic.
Looks like I need AVCC, AGND and ADC pins in order to properly wire the E3D PT100. The documentation mention that newer Smoothieboards comes with header AVCC and AGND pins. The only pins I could find was AGND from the thermistors section of the board. It also looks like I need an ADC pin for signal. Not sure how to identify them. The documentation suggest 1.30 or 1.31, however I have both being used by my Viki2 LCD Display. Another documentation also mention the signal thermistor pins (0.23, 0.24, 0.25 and 0.26) as ADC, however looks like they cannot be used due to how PT100 works compared to regular thermistors.
I also read posts with people saying the board was designed for ultimaker and not to be used on the smoothieboard, but also read that Smoothieboard support the E3D PT100 Amplifier board.
At this point I am not certain where to connect any of the pins and I am afraid of killing the ADC port. Can someone tell me how they wired the E3D PT100 Amplifier board to the Smoothieboard ?
Appreciate it, thank you
