BLTouch trigger issue on RRF 2
-
Please post your config.g
You may not notice the probe status changing in DWC because the BLTouch triggers and than immediately resets, so it doesn't always get captured by the interface. The best way to test is to send G30 to try actually probing and then triggering the pin manually to see if it stops motion. If it doesn't kill power.
Also make sure your white wire from the BLtouch is good. That's the trigger signal wire.

@Phaedrux
Glad to hear on the probe status speed. I was going by one of the tutorials and it said it should show 1000 when triggered. I did try the G30 and it deploys the probe and moves z. Unfortunately it crashes (or I Estop it). The white signal wire is good all the way to the board.

Can you verify that you're still on RRF2 by sending M115 to get the firmware version?
Your config looks ok, except for the dive speed in M558
M558 P9 H5 F1000
Use F60 for the BLTouch.
Are you super sure the white wire is good? Not triggering would indicate the white wire isn't connected.
You could experiment with this since its a BLTouch 3.1

@Phaedrux
Yup, Im super sure.
When I unplug the black and white wires from the probe connector on the board the interface shows the Z probe at 1000 in red. It goes back to 0 when I plug it back in.The M280 isnt working - returns a invalid servo index 0

That means your deploy and retract files are formatted for rrf3 I think. Post them.

Open bed.g and delete/comment the M307 line for the heater channel you are using to drive the BLTouch servo
I just got mine working last night.

What exactly are you sending for your M280?
Does M401 and M402 work to deploy and retract?
-
@64bit Its already been done. Thanks!
-
@Phaedrux No my 401 & 2 does not.
Im not sure what you are asking about the 280 -
if m402 and m401 does not work, there is a problem with your wiring.
the extension wire of the bltouch tend to give poor connections. connect the bltouch directly and test again.
-
Can you send M98 P"config.g" in the console and post the response?
When you say M280 isn't working and giving you that servo index 0 message what exactly did you send for your full M280 command?
-
-
Can you post a photo of how you have the BLTouch wired?
Your config.g is using heater 3 pin on the expansion port. Are you connected to the right pin there?
If you send M401 and M402 they don't work?
If you sendM280 P3 S10 I1does that work? -

M280 P3 S10 I1
Yes, 401 and 2 retract and extend the pin.
Yes I'm connected to the right pin on the expansion header - just like in the setup pics. -
I am having the same issue! my config.g looks the same as above and M401 and M402 both work. I did notice that the trigger type listed in the Z-Probe section of the Machine Properties tab says Unknown (9).

Ok, but before you said it didn't, so I'm a bit confused.
If it's just not triggering while doing a probe with G30, then again I say

@Phaedrux Sorry for the delay.
I just wanted to thank you for all your help!
It was my own bonehead mistake. I had originally used an knockoff BL and totally forgot that I had put the resistor across the signal to ground wires inside the harness.
Using my meter I finally figured out the issue with both ends unplugged.
I removed the resistor and it g28 and g29 perfectly!!
I was going out of my mind!
