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

Open pins_GT2560.h, find

Code: Select all

#define FIL_RUNOUT_PIN     24 //X_MAX_PIN

Replace with

Code: Select all

//#define FIL_RUNOUT_PIN     24 //X_MAX_PIN

or remove the line all together.

Try that but I don't think that should solve the problem but, you could try.

x_min should be triggered if X is homed.
z_min should not be triggered if 3DTouch is in normal state and not triggered. It should show LED on, not blinking or off.

My 3d touch work, the led is power on after test procedure like we can found on geeetech manual.

I will test, thanks

[NiklasO]

I am printing now but this is how it should look when the 2 micro switches not triggered:

Code: Select all

20:34:12.576 : M119
20:34:13.359 : Reporting endstop status
20:34:13.359 : x_min: open
20:34:13.359 : y_min: open
20:34:13.359 : z_min: open

I remembered now. I had to flip the connection to Z min from the 3DTouch sensor. I have extended the leads going to the 3DTouch so I had the same color on them.

[NiklasO]

Make sure that you have the cables to Z min in this order:

If already that way, switch them over and try M119 again. You want Z min to show open.

Thanks a lot, the connection is ok.

otherwise I release x end stop by manually moving extruder to the right and the y is released too

Z is actived because it's the 3d touch sensor, it's led is red fixed.

20:40:52.126 : Reporting endstop status
20:40:52.126 : x_min: open
20:40:52.126 : y_min: open
20:40:52.126 : z_min: TRIGGERED

So the printer must work, but it's not the case...I'm lost

As long as you have z_min: TRIGGERED it won't work. If you disconnect the 3DTouch completely, does M119 still report TRIGGERED?

[Rv8]

I completely disconnect the 3d sensor and I have

20:47:11.149 : Reporting endstop status
20:47:11.149 : x_min: open
20:47:11.149 : y_min: open
20:47:11.149 : z_min: TRIGGERED


so what is the problem please ?

[Rv8]

do you think my solder are not good on the board ?

maybe I must to correct that again

//#define FIL_RUNOUT_PIN 24 //X_MAX_PIN

to

#define FIL_RUNOUT_PIN 24 //X_MAX_PIN

No, you don't need that if not using a filament runout sensor (I have one).

If you could measure the pins for z min and check that you don't have contact between them when nothing is connected.

Also, if you can post images from the front and back of the GT2560, I can take a look at your soldering.

[NiklasO]

Also, connect the 3DTouch again, restart printer then,
Send M280 P0 S10 (it will push the pin down, led should be off, do not touch it)
Send M119

Post the output here
