Setting up Z Probe M558 problem
-
I need help setting up my BLTouch 3.1
When I add the code M558 P9 F100 H5 R0.2 T6000 A5 B1 it sets the Z-probe to 1000. When i add the I1 to invert the signal it goes to 0. All the actions, drop pin, raise pin, test, and reset all work. The issue is when I go to home the z-axis, it never triggers. I set it up using BeTrue3ds set up and changed P5 to P9.
Let me also add that this issue started when I added a Mosquito hotend and thermister.
Any help would be appreciated. -

I say again...

Have you tried the static test described here? https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
Are you saying that triggering the pin during a G30 move does not stop the movement?

Board is Duet Wifi 1.04
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
Duet WiFi Server Version: 1.23The issue is the input for the probe is always high. So when the probe is started it stops right away.
The probe input is high even when there is no probe attached. I did not have this problem before I added the new thermistor.Thank you for helping so far
