Goodmorning, yesterday i have installed 3d touch . but i have some problem. When i write the g28 code work well and go to home,the 3d touch reaches the base and stops . but when i write g29 ,goes into first corner (led of 3d is off) with the pin all lowered, but when touch the base it never come up and i force shutdown for not create damage.

Hi, Hi, you need not put another G28 after the G29 as it will just remove the G29 results.
and the G29 command should be added every time.
for specific operations, you can refer to this:http://www.geeetech.com/wiki/index.php/ ... ing_Sensor
I hope this can help you.

yes but when put g29 only code for bed leveling, it s goes down to much. how can modify the height

but when put in home is perfect

Hi, Whether you have calibrated 3d touch, you can refer to this:

Code: Select all

M280 P0 S10

; pushes the pin down

Code: Select all

M280 P0 S90

; pulls the pin-up

Code: Select all

M280 P0 S120

; Self-test – keeps going until you do pin up/down or release alarm

Code: Select all

M280 P0 S160

; Release alarm.

Hi everybody,

hope someone can help me.
I think I have read all the issues you got on the topic "3D Touch", but unfortunatly I didn't find a solution for me.
First of all: I have a I3 Pro B with 2650 A+ (if I corretly understand, it could mean something since I have the 3D Touch pins close the Extr. Term.).

I followed the steps (many times) on the manual but it is for 2560.
According to the firmware available in the forum I got the firmware already set up for my printer. Easy (I checked if the instructions are in place...there are)

Finally I can drive the command M280...all of them
I have set up the printer (as indicated in the instruction)..BUT (of course there is a BUT otherwise I was printing at this moment..)
I can't go further with the calibration since when I send:
M851 --> echo:Z Offset : -0.50
M851 Z0 --> echo:Z Offsetz_min: -15zmax: -5
G28 --> the printer starts to set home: ok for X and Y axes but for Z is a mess! The nose of the 3D touch seems to work but it doesn't stop anything so the extruder touch the bed,,,pushing and pushing the bed so I have to send the stop command...and the 3d touch is fashing

Where is the problem?
thanks,

SOLVED
in my case the problem was related to wrong connection with z stop: I have readed (in this forum) there wasn't a polarity.
Just swap the cable,,,and is ok,

About calibration...it should be easier, Geeetech thanks to provide detailed information for EACH of your product, not easy or serious have to spend 20 hours for a plugin (from the same brand).

Ciao,
