If you have an AC bed turn the heat off during this step. If you have a direct drive printer
disable steppers as well to make sure E is off. This mitigates any potential EMI from the bed/e
motor.
The adjustment screw is on the SIDE of the sensor and gold/brass colored. Some mounts may
cover it up. If this is the case hold the sensor in position while calibrating it and then secure the
sensor with the included nuts after calibrating.
If the sensor
RED LED
is already on, turn the screw counter-clockwise until the
RED LED
turns
off. Now turn the screw clockwise slowly until the sensor
RED LED
turns on. Make sure the
RED
LED
stays on when you remove your screw driver AND move your hand away from the sensor. If
it shuts off or flickers when you do this turn it just a hair clockwise and move the screwdriver
and your hand out of the way again.
RED LED Turning off?
- Repeat the clockwise adjustment until the
RED LED
stays on when you
remove your screwdriver and hand from the sensor. If you are having issues getting the
RED
LED
to stay on check the grounding on your machine, visit our Knowledge Base on grounding
checks and how to perform them.
Do NOT change the sensitivity if you are getting different heights between prints due to temperature
changes. This should be handled by the Z Offset/BabyStepping the Z height. Under normal conditions
at most you should only have to occasionally Babystep small amounts. If you are getting more than
that please contact our support to go through more advanced troubleshooting steps.
Large babystep changes are usually related to a physical machine issue if M48 is returning a consistent
reading under 0.01mm.
