help with my i3 pro c & 3dtouch

Post by superfly4545 » Sun Mar 15, 2020 10:16 am

I'm new to 3d printing and after getting pro c and only using one extruder and having so many issues with bed leveling I decided to get the 3dtouch thinking it will make things easy. and it been a nightmare. I found frameware on this thread downloaded the file made the changes and upload it using Arduino 1.0.1 because it was the only one that didn't give a compile error.

then it uploaded with no issue and when I send a print X seems to have changed direction and z stops like 1 inch from the bed and starts to print in mid-air. :cry:

I soldered the extra pin properly and all connections are correct. i have the GT2560 old board so i had to solder the extra pin.

its going crazy. i have an older version of the geeetech i3 pro c with the mega 2560 not the rev a or plus.

can you please help.

my printer now has become a very sad paperweight.

thank you any help will be much appreciated

Hi, is this happen to all the models you print,
When changed to firmware with 3d touch,
Whether to perform calibration processing,
And change the save settings.

actually I can't even get it to start printing. the 3dtouch just stops and the Z axis try to break my printing bed.

Hi, do you calibrate the 3d touch itself,
The z-axis limit switch can be removed
3d touch functions as a limit switch.
You can refer to 3d touch: https://www.youtube.com/watch?v=_RtsZDbR2po
Perform calibration.

thank you again for your time. i looked through my LCD display and now i dont see the BLTouch self test option anymore. not sure what i did for it to go away.

Hi, are you update the firmware?
about the pro c firmware you can refer to this:viewtopic.php?f=20&t=17046

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
