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

[daveapplemotors]

It looks easier to rewind the coil on the 3D touch than it is to rewind a motor; and I have rewound many small BL motors. If you don't have any wire I can mail you enough to do the job. I have 30#, 32# , 34# and 36# wire here. Measure it in thousandths of an inch.

I don't know which side of the pond you are on from your profile, though. I am in the USA.

#daveapplemotors Thank you for your help and offer. I'm from Europe so it doesn't make any sense to send it to me. I will gave it to my friend and he will rewind it. But I'm still angry as hell...

#shiva.

Add some pictures, it will be much easier to reply with solution.

Hi Ajey
pls check attached image in 1st image i soldered 3rd pin.In second picture wiring.I onneted Black-Brown,Green-Orange,Blue-Red and in 2 pin section connected Blue-Black and Red-White.

Wow. You should solder on bottom not on top. It looks burned. Try to solder on bottom maybe you didn't solder enough.

[daveapplemotors]

It is easier to solder on the bottom.

Ya,I soldered backside also .I made small hole and through hole i put the pin and soldered.Please tell me how to check it properly sold?any particular signal or current will come?

Ajey - What was the firmware problem you mention? I have the same problem: installed the 3DTouch sensor, modified firmware as indicated in the Wiki, my sensor responded properly to the M280 P0 S10/S90/... commands, but I just cannot get the thing to work. For instance, the final steps on the wiki (calibration) assume that you could have a negative Z ("lcd shows Z=0 ... move Z slowly down"), but my firmware does not allow you to move Z to negative values. If I just go ahead and follow the calibration steps (starting from a manually levelled bed) I get the effect that you mention: the extruder moves to all corners, the pin comes out and and retracts in each corner, but it moves further up after each corner. And since I cannot control it to negative values (there has to be a way and I don't know it), all I can do is to install the no-sensor firmware, and home it the normal way (reconnecting the Z min sensor, of course).

I didn't do it as described in manual... and on a first run when I thought everything was in order my 3dtouch broke down, so I didn't test it. I hope that I will have some time and repair it this week and try it out.

But I must say that it is much more complicated than I thought it might be.
