Problem with thermistor

Seems I've been here before. Gen 3 electronics. Difference this time is software compiles and installs. Problem is temperature say's 0. software runs but always says t:0. I've had similar issues before but then the software would just hang and the issue was usually SCL/SDA D9/D10 issue. I have swapped out the mother board with another and swapped out the extruder board (albeit with extruder boards with other issues) but the temp always worked. I have placed a new thermistor right on the extruder board. always says 0 ?? Note: I am evolving to ramps and have bought same which I hope to use on a new prusa that is almost built i need the mendel to finish making parts. any ideas ??

Have you considered gen3+ ? [koti.kapsi.fi]

hmm that does look tempting. I have makerbot electronics. Is that hard to get to work ?

I haven't tried it myself, but for regular gen3 it should be nothing more than building it (pcbs are here: [www.lulzbot.com] ), plugging it in and uploading a firmware with the correct pinout.

don't mean to sound ungrateful but after looking at the parts list and trying to identify and find the parts and then adding the "upload the firmware with the correct pinout " might send me into a rabbit hole that I may never find my way out of. I think I'm ok building if there are good plans and directions. Still find it strange that everything seems to work except the temperature always says 0. I think I did upload a newer version of the software I wonder if that did something to me original setup ??

Well since I haven't heard anything else on this thread, I believe with these electronics I will try the 3+ approach. I'll let you know how it all goes.
