      I'm not certain what the cause is. Right after I posted the original post I did some testing where I would manually put on the heater then run a M401 followed by the M402 and both worked. Then I tried the various PWM fans and was still able to run the M401 and M402. To take it one step further I added the M401 into my starting script before and after each PWM item was turned on, and it still worked.

      Now after that print completed three days ago I tested the M401 and M402 and they still worked a few hours after the print completed. I have waited now two days and I just tried the M401 and M402 and M280 commands and the BLTouch is not responding.

      Here is my firmware config
      Board: Duet 3 MB6HC (MB6HC)
      DSF Version: 1.2.4.0
      Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.0 (2020-01-03b3

      Here is the probe portion of my config.g
      ; Z-Probe
      M950 S0 C"io4.out" ; Set pin4 out as servo out 0
      M558 P9 C"^io4.in" H3 F200 T12000 ; set Z probe type to BL touch and the dive height + speeds
      G31 P500 X55 Y48 Z2.776 ; set Z probe trigger value, offset and trigger height
      M557 X-115:185 Y-120:120 S60 ; define mesh grid
      M280 P0 S160 I1 ; Reset Probe just in case
      M402 ; Retract probe just in case

      Here is the starting script of my slicer
      M401 ; Deploy probe

      M402 ; Retract probe

      T1 ; First nozzle

      G90 ; Absolute positioning
      G92 E0 ; Set extruder to 0

      M106 P4 S[extruder3_temperature] ; Turn set chamber fan speed (speed depends on Filament)

      G0 Z0.5 F900 ; Raise nozzle to .5mm over bed

      ;M201 X600 Y600 Z100 E10000 ; Set acceleration
      ;M207 X5 ; Set Jerk
      M400

      There really seems like there is actually a glitch in the firmware, or some combination of commands is affecting the servo action of the pin I'm trying to use. The BLTouch works fine until either a print is started, at which point it stops working, or if a print is started right after a reboot it works fine for the print and then stops working sometime after the print is completed. This really doesn't seem like a configuration gcode issue but more of a glitch in the firmware.

      I'll be back in the office tomorrow and with any luck there won't be a power outage so I will be able to connect an oscilloscope to the servo pin and see if there is a problem withe the signal wire.

        So this entire section is your starting script?

        Can you post your full config.g and homeall as well as a sample sliced gcode file?

        It also looks like you are on FW version 3.0. Please update to 3.1.1

          Is it also worth mentioning that there isn't blue light on my BLTouch ever. I'm not sure if there is supposed to be or not but I have read that the blue LED indicates if the servo line is active.

            The fact that it seems to be intermittent makes me think wiring. BLTouch wiring and crimps are a very common cause of issues. Double and triple check.

              @Phaedrux Yes that is the starting script from my slicer. The M401 G4 S2 and M402 was just thrown in for diagnostics so that I could see if the probe was going to work or if it is related to the some other output channel being active.

              It doesn't appear to be the case and I will eventually remove all those. Some of it is pointless and left over from the printer manufacturer that built the printer originally. I have since modified it heavily and moved to the Duet 3 board.

              I popped into the office to have a look at the BLTouch and I tried disconnecting the BLTouch and reconnecting it. When I reconnected it, it did the two probe deploy and retract that it does when it powers up. But I could still not deploy or retract manually with the M401 and M402 respectively. I then connected my oscilloscope to the servo wire and I could see that there was a signal being generated and the signal was different for the M401 and the M402, so the servo pin seems to be functioning. The BLTouch however did not respond to the servo signals, even though I did a power cycle to the BLTouch.

              I then reset the Duet 3. After everything homed and the config.g finished executing I was then able to send the M401 and M402 command and they worked correctly. I still had the oscilloscope connected and the signals were the same as before I power cycled.

              This makes no sense. If it was the BLTouch you would think that the power cycle to it would have gotten it working. If it was the Duet 3 board then I should have seen some difference in the servo signal as that should be the only thing that the BLTouch can see with respect to the board.

                @Phaedrux I'm not using any of the BLtouch factory crimps. I removed the dupont connectors and added my own Molex connectors and the crimps are tight.

                I agree that he issue is intermittent but it is not intermittent in a way that would indicate loose wires. It seems to be time sensitive, the longer the duet has been running (and so too the BLTouch) the greater the probablity that the probe will not deploy or retract. Additionally once it fails to deploy or retract there is no bringing it back without a Duet 3 restart.

                  Before we can do much other troubleshooting the obvious thing to do is update the firmware to 3.1.1 and see if the behaviour is persisting.

                  What version of BLtouch is it?

                    Here is the whole config.g that you requested in case there is something in here. I had everything working with an IR sensor before I switched to the BLTouch, so perhaps I missed something when I changed the Z probe type.

                      I would recommend removing the homing commands from your config.g. Definitely not best practice to have movement commands executed at startup.

                        @Phaedrux it is the Smart 3.1 BLTouch, I think that is the newest version.

                        I will try the update to 3.1.1 for the Duet.

                            @baird1fa if the update doesnt help:

                            I read in another thread that the heater disturbed the bltouch. One solution was to assemble the bltouch at a different position. The other means was to protect the cables with a shield, which can be bought separately and is around the cable.

                            It looked similar like the shielded cable on the left here in this link https://www.antclabs.com/wiring

                              @Phaedrux I have completed the upgrade to the latest version of the firmware. I tested the BL touch and after the update I was still able to deploy and retract the probe, so I started a print and the probe did not deploy. I hit the E-stop and then started the print again and the probe worked fine.

                              Now that the print has completed, I cannot activate the probe. I'm going to replace the BLTouch with a spare one and see if that has any effect.

                                @baird1fa said in BLTouch does not deploy for a print:

                                I'm going to replace the BLTouch with a spare one and see if that has any effect.

                                Good next step. Redo the wiring if possible as well if just changing the probe doesn't help. The intermittency really seems like a wiring fault.

                                  @Phaedrux It really seems like something other than wiring. I can do exactly one print before it the servo signal doesn’t work. It really makes me think it is something that is in my slicer code but I don’t have anything strange there.

                                  I have noticed since my upgrade to firmware 3.1.1 that I have a termination error at line 106 of my config.g macro. Line 106 is the latest line of my config.g

                                    Ok that's something worth looking into.

                                    Send M98 P"config.g" and report the results.

                                    Maybe include your current config.g as well.

                                      I’m just in the middle of a print so I will do that once it’s done. Also the config is the same as previously posted.

                                      Regards.

                                        @Phaedrux I found that issue, It was my M911 command, I seem to have forgotten to close the quotations (") and so it wasn't understanding that command. So I'm pretty sure that is a completely unrelated issue.

                                        But back to the matter at hand. The BLTouch will not deploy after I start a print job.

                                          I don't know what's in your homeall, but it should be homing Z with the probe already, so you should remove everything after G28.

                                          I'm not sure what that's trying to accomplish.

                                            @Phaedrux no my home Z does not use the probe, nor does my home all. As you can see in my config.g I'm using a limit switch as the maximum Z for the home Z. The probe is only used for the bed mesh.
                                            that is why I haven't posted it sooner is it has nothing to do with the probe.

                                            The issue is 100% repeatable so it is not the wiring. If I use the probe a few times or use the macro, before I print a file, the probe will not deploy. If I print a file, after the file is complete the probe will not deploy. And when I say deploy, I mean it won't respond to commands at all. After I reset the board either by hitting the emergency stop button or via power cycle, the BLTouch will respond. It is a very strange issue.
