I3 Pro C with 3d touch major issues

Post by superfly4545 » Wed May 27, 2020 8:30 am

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


// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

#define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS.
#define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below.

// Travel limits after homing
#define X_MAX_POS 200
#define X_MIN_POS 0
#define Y_MAX_POS 200
#define Y_MIN_POS 0
#define Z_MAX_POS 180
#define Z_MIN_POS 0

#define X_MAX_LENGTH (X_MAX_POS - X_MIN_POS)
#define Y_MAX_LENGTH (Y_MAX_POS - Y_MIN_POS)
#define Z_MAX_LENGTH (Z_MAX_POS - Z_MIN_POS)
//============================= Bed Auto Leveling ===========================

#define ENABLE_AUTO_BED_LEVELING // Delete the comment to enable (remove // at the start of the line)
#define Z_PROBE_REPEATABILITY_TEST // If not commented out, Z-Probe Repeatability test will be included if Auto Bed Leveling is Enabled.

#ifdef ENABLE_AUTO_BED_LEVELING

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

// - "grid" mode
// Probe every point in a rectangular grid
// You must specify the rectangle, and the density of sample points
// This mode is preferred because there are more measurements.
// It used to be called ACCURATE_BED_LEVELING but "grid" is more descriptive

// - "3-point" mode
// Probe 3 arbitrary points on the bed (that aren't colinear)
// 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
// AUTO_BED_LEVELING_GRID_POINTSxAUTO_BED_LEVELING_GRID_POINTS grid
// and least squares solution is calculated
// Note: this feature occupies 10'206 byte
#ifdef AUTO_BED_LEVELING_GRID

// set the rectangle in which to probe
#define LEFT_PROBE_BED_POSITION 30
#define RIGHT_PROBE_BED_POSITION 200
#define BACK_PROBE_BED_POSITION 147
#define FRONT_PROBE_BED_POSITION 20

// set the number of grid points per dimension
// I wouldn't see a reason to go above 3 (=9 probing points on the bed)
#define AUTO_BED_LEVELING_GRID_POINTS 2


#else // not AUTO_BED_LEVELING_GRID
// with no grid, just probe 3 arbitrary points. A simple cross-product
// is used to esimate the plane of the print bed

#define ABL_PROBE_PT_1_X 20
#define ABL_PROBE_PT_1_Y 150
#define ABL_PROBE_PT_2_X 50
#define ABL_PROBE_PT_2_Y 100
#define ABL_PROBE_PT_3_X 100
#define ABL_PROBE_PT_3_Y 75

#endif // AUTO_BED_LEVELING_GRID


// 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
gala

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?

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

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.
