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

[alfqueen]

Good afternoon, I could tell someone that pin is used for a motherboard ramps 1.4.

[bang]

Hi does anyone else have the pin twitch from side to side when they use the M280 P0 S10 ; pushes the pin down.
Then when i try to use the M280 P0 S120 ; Self test, it just does an error til i reset it.

Any ideas what might be causing this

Hi,

Hi,Roberto
Did you check this post before?
http://www.geeetech.com/forum/viewtopic ... 27&t=18371
You said " when I send the auto test script (M280 P0 S120), the pin is just pull and push one time",what did it do after pulling one time?Keep flashing or something else?
Normally,it should have been pushing and pulling all the time(send M280 P0 S120) until you send next commend.
I guess the needle inside the sensor was not adjust well.

Hello,
Thanks for your answer.
Yes, I took a look on this topic.
I have already tried some different adjustments of the needle and also following the procedure of this video (https://www.youtube.com/watch?v=Ix7lXvf ... e=youtu.be), but no success.
When I send M280 P0 S120 the pin pull and push and the led keeps turn on.
I found a way to manage the issue of less of repeatability.
I set to zero the retract of the Z axis home (#define Z_HOME_RETRACT_MM 0). After that my problem was solved.

Hi, my 3d touch works, but I can not store the calibration, position the print head with the prize M500 and repetier display stores data, but when I press the G28 head returns but still remains distant as before.
where am I wrong?

Hello all.

I just recently bought 3dtouch sensor for my i3 b pro. I have followed all the wiki instructions.

I have a problem when I click home button the Z axsis goes only up and does not auto level the bead. When I power up the printer the 3dtouch does what it is spouse to do, but when I try to use printer, it doesn't work.
I have tried to upload firmware from this site, but the program alerts me that something is wrong in the file... please help me

Thanks

First did the sensor have the response to the four rows of Gcodes(M208 P0 S10/90/120/160)?
Did you have all the wiring correctly connected?Check the continuity with the multimeter if you did.
