Probe macro issue

PaulHew

I have a macro which is giving me the following error
1/23/2020, 3:03:41 PM M98 P"0:/macros/Probe PMFH"
Error: Invalid gpio port 64

The macro is for probing the bed with a BL Touch. These are the lines in it

G1 Z10
M280 P64 S10
G30 S-1

I recently upgraded to RRF3 and not sure what I need to change it to.

Assistance would be appreciated.

Regards,

Paul.

@PaulHew In you config.g you'll have something like:

; Z-Probe
M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
M558 P9 C"zprobe.in" H5 F120 T6000             ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5                            ; set Z probe trigger value, offset and trigger height

Where M950 S0 creates the servo pin/index. Unless yours says M950 S64, the M280 in the macro is wrong, and should be M280 P0 S10. See https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M280_Set_servo_position

Thank you both.

I got lost as this is on my maestro board and the example is for a Duet2.

I still have not got my head around the pin numbers, assigning and referencing them.
New learning curve!

Thanks again.

Paul.
