Revo Voron PZ Probe firmware configuration?

@SpeedyDad I wasn't suggesting that you change the input pin (it depends on where you have the pz probe connected). Your original M558 was:
M558 P8 C"121.io0.in" H10 F700 T16000and I was suggesting that you could change it to something like:
M558 K0 P8 C"^!121.io0.in" H10 F700 T16000 M558 K0 P8 C"^!121.io0.in" R0.5 H5 F400 A2 T24000 M558 K0 P8 C"^!121.io0.in" R1.0 H5 F400 A5 T24000E3D is also suggesting that you turn off the heaters (the B1) but I don't do that and it has been working well for me.
All that said, if you have the correct pin in the M558 command with ^! and it shows not triggered when idle but when you tap the hotend the www interface doesn't show the z probe triggered then you have a problem. You can post your config.g and maybe I (or someone) can suggest a problem. Also, are you sure your crimps are good?
The "commands section" is for non-standard usage of the probe or to reprogram the settings. You can ignore that until you find you want to do one of those things.
Yeah, I understood what you were saying. The changing the pin was just in case it didn't like the io0 input. I tried your example and theirs. Is yours up and running?

@SpeedyDad Yes, I have a PZ Probe connected to a (regular, not roto) Toolboard, two running on an IDEX printer with a 3HCL expansion board (I use them to calibrate the tool offsets when starting a multi-material/colour print) and one on another printer just plugged into the regular control board. All of them are working great and I have plans to install more of them.

What firmware version are you running?
-
@SpeedyDad Two of the machines are running the latest stable (3.5.4?) and the idex printer is running 3.6.0-rc2+2 (for a bug fix needed to calibrate the tool offsets).
it sounds like you're not getting anywhere. I would suggest that you do the following:
- post your full config.g
- try to get a good picture of the wire connections at the pz probe pcb and the toolboard pcb to show how it is wired (and post it here)
- verify that when you tap the nozzle, the triggered light on the pz probe flashes
- verify that when everything is idle that the probe status shows 0
- verify that when you tap the nozzle, the probe status flashes to 1000
If one of those things don't work, that's the first problem you need to fix.
if all that works, then I would manually (or via a G92 Z0 G1 Zxx) make sure that you have a large space between your nozzle and your print bed and then run G30 S-1. Let the probe run a for a couple of seconds to make sure it isn't false triggering and then tap the nozzle. If it doesn't stop, hit emergency stop.
If you want to try those steps and report back along with your full config.g, I (or someone else) may have a suggestion.

@SpeedyDad I just changed from a klicky probe to a PZ Probe on another printer this morning. The only config changes I had to make were to change:
M558 P5 C"^io1.in" H5 F200 T24000 G31 X0 Y22 Z3.625 P25to
M558 P8 C"!^io1.in" A5 R1 H5 F400 T24000 G31 X0 Y0 Z0 P100 -
Sorry all. Got a little busy with other things. I'll work on this with the above suggestions in the AM. I appreciate the help.

OK, Here are the results of above:
My connections to the Roto toolboard are as follows. Red from the PZ Board = io1 +3.3v. Orange from PZ Board = io1.in. Brown from PZ Board = GND. I have verified continuity at both ends of the signal wire.
I get a power LED on the PZ Board.
I get a flash of the amber LED when I tout the nozzle end.
Probe shows as 0 on the panel when idle.
Probe does not flash to 1000 during trigger
Running a G30 S-1 and tapping the probe does nothing.My config.g

Your wire connections look correct. The PZ PCB is reading the piezo probe correctly. But the firmware is not correctly reading the triggered value. That would most likely be a bad crimp or a misconfiguration. I think it's the misconfiguration because you have:
M558 P8 C"!^io1.in" A5 R1 H5 F400 T24000which would be the io1.in pin on the main board. The toolboard would be xxx.io1.in where "xxx" is the canbus address of the board. From the comments around the zprobe and previous posts you've made, I'm guess that it should be:
M558 P8 C"!^121.io1.in" A5 R1 H5 F400 T24000 -

M558 P8 C"!^121.io1.in" A5 R1 H5 F400 T24000Ah, good catch. It was set to 121 but I changed it and forgot the 121. Now, it does register a 1000 when the probe is touched and I was able to run G30 S-1 once. After that, trying to run it again got the error:
"G30 S-1
Error: G30: Probe was not triggered during probing move"Some leftover stuff from trying to probe with the BLTouch I'd imagine. Progress is being made though.

Success! After restarting the printer, I was also getting errors "G90: Probe was not triggered during probing move" after it finished its homing moves. I looked in homeall.z and it ended in a G90. That really shouldn't have impacted it so I commented it out and ran it again. This time, no errors. To test it again, I removed the ; to comment it out and it still ran fine. No errors. Go figure. I am now able to get it to home properly, do a 4 motor gantry level and run mesh compensation. Mesh compensation takes forever now because it probes the bed twice at each point and, over a 400mm square bed, that takes a lot of time. I'll tweak its settings.
Thanks all for the help. This forum is one of the best out there for solving issues.
