Well,

i ended to go back and unmount the 3d Touch.
I will try again in few days.

It could be the firmware, but i did not find anything wrong.
i still search.

thanks for your help, i ll be back later after new tests.

Did not find how to edit , so i go on hereunder.

I home X by G28 x0 and Y G28 Y0
then i go to G0 X100 and G0 Y100

at this step everything is correct.

but if i try to home Z, it only goes UP. !! strange! no?

Another info:
LDC displays this " Z probe out. bed"

something wrong with my firmware i guess! but i don't understand what...

Ok, i assume sensor would be ok.

Safe Homing:

I guess yes . in the firmware. configuration.h:

//If you have enabled the Bed Auto Leveling and are using the same Z Probe for Z Homing,
//it is highly recommended you let this Z_SAFE_HOMING enabled!!!

#define Z_SAFE_HOMING

it seems enabled ...

@Undcon: i gonna check again the firmware and all steps (it just will be the 20st time i do it! )
@daveapplemotors: it should light on when lowering? because , in my case, it s light on, when pin is up (in contact) , and off when pin is down.
nevertheless, it tried what you suggested.. nothing.

Sorry, i mean M command and not G : M280 P0 S10 etc..
no movements.

Any idea? is it possible to check the sensor another way. or check that the board is ok?

Hi,

Thanks for your reply.
I checked the wiring. To be sure, i soldered each wire and verified the continuity with a multimeter. this point is OK.

the firmware is the one of this topic. first page: Marlin-PI3_Pro_B_3DTouch.zip

i tried the G command. Nothing happens. The red light is always on.

Hi ,

I read all the thread but did not fine any answer to my problem.

When i start the Printer, the 3Dtouch only make 2 movements , not 3.
and i m unable to make it up/down/ selftest with G commands.

nothing happens (just the 2 movements at the start of the printer.)

Do anyone have an idea?
