# Inductive Sensor Causes Print To Stop

Just added inductive sensor to my printer (MKS Gen L Board) using Marlin 1.1.9 After some tweaking it works great! The problem is when it starts print the sensor detects the bed and stops the print because it gets triggered.

Can I tell Marlin to ignore the Z-min readings while printing?

• Are you using the sensor as a normal endstop or did you modify the firmware to enable automatic bed levelling? – 0scar Jan 1 at 0:49
• i was able to solve it, here is my Configuuration.h file bitbucket.org/OrAzran/marlin_sxw1/src/pinda/Marlin/… – or azran Jan 6 at 8:13
• Great! Please post the solution as an answer. Copy the interesting parts of the configuration file in the answer. This may help other users with the same problem! – 0scar Jan 6 at 8:42

Solved the problem, I was missing this line:

#define ENDSTOPPULLUP_ZMIN_PROBE


Apparently the sensor required a pull-up to better define the signal.

• Thanks for posting the answer! I removed the link to the configuration, the pull-up hint should be sufficient for a self-contained answer. Also, linking to external content is usually not very wise as all things on the internet die from link rot eventually. – 0scar Jan 6 at 9:11
