Thermistor Error Ramps 1.4 (MINTEMP) Hi, I'm new here and building my first 3D printer and I have a number of problems. For one I am not getting any readings from the thermistors. I measured the resistance to make sure they all work and connected one of them to all three sockets. Still I am getting the MINTEMP error. Second the y axis is not moving. I switched the motors on the x and y axis, so the stepper is okay. This might be fixable by changing the pins from E1 to Y, but that won't fly without the thermistors working. The printer is using a Base V1.3 board which combines the Arduino Mega and RAMPS 1.4 electronics. I fear that there might be a defect on the board, but I have no clue how to check the circuitry. Did any of you have similar problems or have any idea how to fix these issues? Thanks for listening to my troubles :( https://reprap.org/forum/read.php?219,570976,570976#msg-570976 Tue, 21 Jul 2026 02:54:51 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,570976,571215#msg-571215 Re: Thermistor Error Ramps 1.4 (MINTEMP) https://reprap.org/forum/read.php?219,570976,571215#msg-571215
For the mintemp error make sure that the wires have continuity. If you have everything selected in the firmware correctly, and the thermistor shows resistance, it is probably a board issue.]]> gmckee RAMPS Electronics Fri, 16 Oct 2015 00:23:55 -0400 https://reprap.org/forum/read.php?219,570976,570976#msg-570976 Thermistor Error Ramps 1.4 (MINTEMP) https://reprap.org/forum/read.php?219,570976,570976#msg-570976
