BL touch doen't stop (RAMPs 1.6)

Galney

Hi guys !

 

I need your help today about mu BL touch configuration. I watched and read a lot of tutorial about it, but I can’t find the solution for my problem.

When I’m using it, the BL touch can be triggered but won’t stop the Z axis movement, so it can crash into the bed. I have tried a lot of things, but as I’m not good at programming you might see something I didn’t see.

So first, I am using a BL touch, a RAMPs 1.6 and Repetier (and I only used the Repetier Firmware tool)

The BL touch is connected on the Zmin (black and white wires) and on the digital pin 11 and on the 5V and GND of AUX-1 (the one on the SERVOS don’t work because my VCC - 5V doesn’t work, it turns the RAMPs off)

When I turn on the printer the BL touch is running (going up, down then up) and stay like this waiting for instructions.

When I use the command:

-          Probe start script : M340 P0 S700

-          Probe finished script M340 P0 S700

Everything work, the probe goes up or down, depending on the command.

But when I want to use G28 or G29 or just going down controlling directly Z axis, and then the BL touch touch the bed, the probe is triggered but doesn’t stop the movement.

Can someone help me please? I really don’t know what to do.

Here is the configuration:

 Z min pin must be also set to same pin a z probe.
Homing settings should include temperature (which you set 0) so you can define a probing position. Select on like 100, 100 so you have no problems activating probe.
You should raise z before z homing so bl touch is not triggered on activation. Then it goes in alarm mode and you get problems.
Z_PROBE_REPETITIONS 2
should be 1
bltouch does not need more and repeating is difficult here.
M119 should show z probe low.

#define Z_PROBE_Z_OFFSET 0

#define Z_PROBE_Z_OFFSET_MODE 0

#define UI_BED_COATING 0
Just don't start with coating when there is no need to. You already measure surface and that is what you need.

Test if G30 works. Then you can try homing z. With explained settings it should work.
