you have Z_PROBE_SERVO_NR 0 this is fine.

are you sure its a ramps 1.3 ?

as the only difference from a ramps 1.3 to the ramps 1.4 (firmware wise) is the servo0 pin changed

#ifdef IS_RAMPS_13
    #define SERVO0_PIN                         7
  #else
    #define SERVO0_PIN                        11
  #endif

Hi

My first time on this forum thank you for allowing me on .

i have attached both a pic of the servo as well as as configuration.h config..

I have build my own 3d printer in 2018 based onthe prusa reprap, and are running marlin v1.0.0.0 and new really needed to upgrade it is time now..

I have got the homing working after bit of trails and errors but really failing to get the z_probe working on a swing servo...

I would really appreciate any help i can get to get this working soonest.

in using the Aduino mega 2560 with ramps 13 efb board and driver the 4988 drivers

on the attached pic file

i do not get the "red" encircled servo to come down, but when doing the HOME i manually touch the "b" section in blue and this doe take the sensing when i depress the micro switch

i am not very clued up with the in depth knowledge of marlin FW, i have some figured out but really struggling with getting the getting this z_probe servo to deploy ....

I would really appreciate any help ... Thank you in advance

I presume if this servo is sorted will the automatic work on the bed leveling on the Z probing...
