3D Touch Sensor:Auto-levelling for Geeetech 3D printer

[daveapplemotors]

Those numbers in the matrix don't stand for correction at each point.

I don't know what they are for but I get the same kind of results and my 3D touch works well.

can you please send me your firmware?

Where I get the firmware for the Prusa I3 pro C dual extruder 3D and 3DTouch Auto Leveling Sensor
Because I do not come with the guidance and have no idea of programming

Would be nice if one can upload it
Is there still no way to help?

woher bekomme ich die firmware für den Prusa I3 pro C dual extruder 3D und 3DTouch Auto Leveling Sensor her
da ich mit der anleitung nicht klar kommme und keine ahnung von programmieren habe

wäre schön wenn einer es hochladen kann

suche es immer noch kann keiner helfen?

i have an Pro X ( GT2560 RevA+ Board )with Firmware from the 1st page( + changes for the GT2650 Rev A+) + Setup like described on the wiki + mount for the sensor from the wiki. M280 Po S10 + S90 + S160 are working.

if i do G28 -> y,x work, then it goes to the middel and z is going up 3mm, G29 -> the head is moving y + x correct , but z is going up !!!

than i changed the polarity of z-max connection( white - black)

G28 y,x work,then it goes to the middel and z is going down -> sensor touches -> going up again but z is going down further until it( nozzel) is touching the bed.


How to debug this behavior ? Some hint's ?

[daveapplemotors]

What color is the light on sensor when going down to bed? White is good--and pin extended. Red is not--pin retracted and no help!
Maybe this will help. I was stuck where you are for a bit until I work this through.

First prep sensor with -- M280 P0 S160.
Then change color to white with M280 P0 S10
These two commands precede G28 but don't forget G1 Z6 to clear the bed because you just extended the pin.

[daveapplemotors]

I forgot to add that it is normal for the nozzle to go up if the sensor is Red--not extended. It's wired right when it does that.

@daveapplemotors: the ligth is off + pin extended, but see for yourself https://youtu.be/mPHlSE_rdmE

I if i do G28, the sensor pin is going down, the z is going down, if the pin touches the bed , the pin is going up, led switches to red, but z is not stopping

[daveapplemotors]

You are down to just two wires. You are nearly done. Black and white wires from sensor connect to the board.

To Z min stop? I forget but the photos and instructions are clear there.You are almost finished. Is it one of those two wires that gets reassigned in pins.h?
Z min-end stop 32 --??

[schlaubi666]

yes black + white are connected to z-min

pins.h -> i followed the instuctuion of the pdf for Rev A+ so i did

Code: Select all

/*****************************************************************
* Ultimaker pin assignment
******************************************************************/
#define Z_MAX_PIN -1 //32
#define SERVO0_PIN         11  //13 untested for GT2560 Rev A+
#define Z_MIN_PIN 30 

there is no z min-end stop, do you mean Z_MIN_PIN ? this is unchanged 30
