Need help programming Ender 3 Pro a d bltouch
-
I’ve ran through reprap configurator several times trying to get auto calibration set up. It starts by homing off the bed and the probe doesn’t deploy. Like it is looking for an endstop and not using the probe. The probe does deploy on start up like a test.

I suggest you post your config.g and homing files so we can see what the web configurator has given you.
The fact it's doing a self test at startup is promising, that would indicate that it's wired correctly at least. The behaviour you describe would indicate that the homing files just need to be modified.

@3DEric
do you have deploy probe and retract probe.g because it will call when you use bltouch
and to make home at center of bed you have to modifide home z and home all .g to some thig like this; homez.g
; called to home the Z axis

Thanks for the reply.
Are these the right files?

@3DEric said in Need help programming Ender 3 Pro a d bltouch:
G1 S1 Z-265 F3000 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z to axis minimum (you may want to adjust this)This section of home all and home z need to be replaced with a G1 X and Y move to place the probe at the center of the bed and then a G30 to probe z0.
