I got things moving from the answer to a previous question. Now, since the base-video I'm following is non-English, I want the next phase fixed:
After the final adjusted firmware upload, and bringing the sensor up, I see that the extruder pushes the bed down a bit when I auto home and then the LCD screen says probing failed.
If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes:
#define FIX_MOUNTED_PROBE // Line #0719, Uncommented #define X_PROBE_OFFSET_FROM_EXTRUDER 16 // Line # 0779, Was 0 #define Y_PROBE_OFFSET_FROM_EXTRUDER 58 // Line # 0780, Was 0 #define Z_HOMING_HEIGHT 5 // Line # 0870, Was 4 // #define MIN_SOFTWARE_ENDSTOP_Z // Line # 0907 Commented #define AUTO_BED_LEVELING_LINEAR // Line # 0977, Uncommented #define LEFT_PROBE_BED_POSITION (X_PROBE_OFFSET_FROM_EXTRUDER + MIN_PROBE_EDGE) // Line # 1027, Uncommented #define RIGHT_PROBE_BED_POSITION (X_BED_SIZE - MIN_PROBE_EDGE) // Line # 1028, Uncommented #define FRONT_PROBE_BED_POSITION (Y_PROBE_OFFSET_FROM_EXTRUDER + MIN_PROBE_EDGE) // Line # 1029, Uncommented #define BACK_PROBE_BED_POSITION (Y_BED_SIZE - MIN_PROBE_EDGE) // Line # 1030, Uncommented #define Z_SAFE_HOMING // Line # 1144, Uncommented
From the above changeset, lines 1027-1030 are from the other SO question I mentioned above, the remaining are following the video.
After completing the steps up to the point where I push the firmware and have to lift the ROKO up I followed instructions in this video, my "Auto Home" operation is failing.
I used Pronterface as recommended by @dgrat in comments below and got this result:
>>> M119 SENDING:M119 Reporting endstop status x_min: open y_min: open z_min: TRIGGERED
I did not get the Probing failed message this time.
I also went ahead and tried out the second answer, where @0scar is recommending to uncomment
The results are exactly the same: The head hits the hotbed and goes back and then comes down slowly hitting and compressing the spring a bit before stopping. I did not get the Probing failed message this time.
