Hello all, finally got everything wired up to test my homebuilt mini. Limit switches seem to work, homing seems to work. But when going to run a test print cycle i run into this error that the max temp of my bed has been reached. I believe it only made it to about 122, which i doubt is the max. plus it was only slightly warm, not hot. Extruder temp was only about 34. I’m suspecting either the thermistor which came with my heat bed is bad or this is some sort of weird software issue. I am using Lulzbot Cura 17.10 and used it to reflash the firmware for the mini to the mini rambo board.
The closest thing i found was this thread from the ultimaker forum which hints at a software bug and/or the software looking for the wrong thermistor value. https://ultimaker.com/en/community/7445-errortemperature-heated-bed-switched-off-maxtemp-triggered
I have not ohmed out my thermistor yet, but i will soon.
