thermistor bad reading

Does your hotend heat block take a cartridge thermistor or a glass bead?
-
@Phaedrux block thermistor
-
Does it look like the little metal tube in the E3D link above, or does it look like a little glass bead?
-
@Phaedrux small metal tube
-
Then that E3D thermistor is the one you want.

this is the alternative pt1000

@Veti ok we Will see

also I would like to report a bug. when the endstop is positioned upwards for the z axis the platter stops when it touches the endstop but if you give the command again it continues to rise ignoring that the limit switch was already pressed

@ninni said in thermistor bad reading:
M208 X0 Y0 Z-200 S1 ; set axis minima
M208 X230 Y210 Z0 S0 ; set axis maximaNot a bug; you have put in strange values for Z axis minima and maxima. Firmware expects all moves to be in the positive range; no CAM/ slicer outputs negative absolute coordinates.

The reason for that is the G1 H2 Z5 command in your homez.g file. That command tells the firmware to raise Z by 5mm, but that isn't appropriate when homing to max Z. You should probably remove the one in homeall.g too.
