I3 Pro C with 3d touch major issues

[superfly4545]

Hello Everyone.
I'm in dire need of trying to fix my geeetech i3 pro c auto bed leveling issues. i am out of options and is about to smash it after so many attempts to fix it. here I go

after connecting all these pins correctly i uploaded the marlin frameware with the correct configs. i will attach the marlin files and pictures of my 2560 board and some of the errors im getting when i run the code.

at first when i press auto home the printer came to somewhat middle of the bed and homed correctly. the only issue was getting the z axis correct. so then i connect the printer with pronterface and began trying to fix the z axis. and when i try to move the Z down using the manual controls it wont go below zero. then found out every time i try to adjust the z axis offset using pronterface it gives me this error "echo:Z Offsetz_min: -15z_max: -5"

>>> m851
SENDING:M851
echo:Z Offset :
-0.78
>>> m851 z0
SENDING:M851 Z0
echo:Z Offsetz_min: -15z_max: -5

then nothing happens when i even try to turn off the soft end stops
>>> M211 S0
SENDING:M211 S0
>>> M211 S0
SENDING:M211 S0
>>> M211 S0
SENDING:M211 S0

so while i was trying to see what was going on with this i must have cchanged or done something, now when i hit auto home the X and Y axis goes to the nds and starts grinding the gears then the Z comes down all the way at the end of the table around 200,200. i have attached a video of this just to show what is going on.

this is some of my Config...h data

// There are 2 different ways to pick the X and Y locations to probe:

// - "3-point" mode

// You must specify the X & Y coordinates of all 3 points

#define AUTO_BED_LEVELING_GRID
// with AUTO_BED_LEVELING_GRID, the bed is sampled in a

// these are the offsets to the probe relative to the extruder tip (Hotend - Probe)
// X and Y offsets must be integers
#define X_PROBE_OFFSET_FROM_EXTRUDER -6
#define Y_PROBE_OFFSET_FROM_EXTRUDER -60
#define Z_PROBE_OFFSET_FROM_EXTRUDER -1.4

i measured the x offset to be -6mm and Y offset to be -66 however it won't let me add -66 as y-probe offset only lets me do -60 so i left it at -60.
so i reupload the frameware several times but the printer will not home as it did the first time. now the x trys to go off and so does the y just like in the video.

my printer bed is 210 by 210

i now know how to manually send commands using printerface and would like to plead for your assistance. because im am lost.

thank you

Hi，perhaps you set the Z-offset value beyond the range of -15 to 15.

hello
when i measure the actual distance of the sensor from the print head the x = -6 and y = -66 so am I doing something wrong. because i have the i3 pro C which is the dual extruder one the 3d touch is mounter way in the front. how can i fix this?

[William]

Sorry, I do n’t quite understand, can you provide related videos?

[superfly4545]

Hello, here I have attached few pics and a video of how my printer acts when i hit auto home and how my printing nozzle and 3d touch sensor offsets picture distance example. and i also attached the current frameware that's installed on the printer for your reference.

thanks

Hi，it is recommended that you directly use the firmware that supports 3Dtouch, do not change.
