BL Touch Issue on 3.2 Firmware
-
Just setup a bl touch on duet 2 wifi after some fiddling and browsing this forum I found most of the answers to get it to answer to commands M401/402 and macros for self test etc. So all that works, however i'm still stuck with the machine reading 1000 for the probe right after boot up. I tried inverting M558 but that didn't help.
Here is my config.g also i'm connected to pin 8 (heater 3)

M558 C"!zprobe.in" P9 H10 F800 T2000 ; set Z probe type to switch and the dive height + speeds
remove the ! and put a ^ in place
but if the display is 1000 after that you have a wiring problem.
post a picture of your wiring
