Latest Marlin bugfix-1.1.x branch for PI3 Pro B

[Rv8]

maybe i can put the Y endstop switch to the board at Y max ? this will avoid the hit ?

I just send G28 and all axis seems want to go home but Y axis hit the printer so I push the urgence button..

Does Y go in the right direction? G28 should move the bed to the back.

Edit:
Try #define INVERT_Y_DIR false

if i understand the propre is the pin of the 3d touch captor ? if yes, no the pin don't move down

[Rv8]

yes with G28 the bed go to the back but it hit, so I must click on urgence button

Please take a picture of the board with the 3DTouch connected.

About the bed hitting the end, make sure that the wing nuts at the back is turned so that the wing on the nut does not hit the back acrylic, if so, the bed can't go far back enough to trigger the switch.

Edit: This needs to be turned so that the bed can move as far back to trigger the switch:

I try that and upload the firmware

Try #define INVERT_Y_DIR false

but now the bed go to the front and hit the front ....otherwise I have no problem with the wing nuts...

I had the problem with the wing nut extending too far when turned the "wrong" way and my bed was crashing to the back of the machine. The wing nut stopped the bed from moving and triggering the switch in the back. It took me some time to figure out that it was the wing nut, making contact with the back before the bed had the chance to hit the switch.

If it crash to the back with G28, your bed is moving in the right direction. Do you see and hear (*click*) the back switch triggering?

The probe has nothing to do with Y but just check that the colors on the wires correspond to the instructions.

Thanks for your patience and help !

Yes the colors are ok, but I can hear the switch when the bed go to the rear, it's normal but the switch can no function because it is not connected to the board.
on the manual they say to no connect it when use the 3d touch ???

Oh! I see. Are we talking about the same axis here?

X is moving left and right
Y is the bed.
Z is the up and down movement

The probe should replace the Z min switch. Not Y.
You should have two switches. One for Y min (the bed) and one for X min connected to the corresponding ports on your board. The black and white wire from the 3DTouch should be connected to Z_MIN.

Yes I just notice that I'm tired..
have you got a picture of your end stop connection board please ?

Thanks
