@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.
See example here https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_using_a_Z_probe
