BLTouch working, then not working, then working for a bit...

also check the wiring. a lot of people have problems with the bltouch extension cable.
that could cause intermitten connection problems. -

I found a brand new BLTouch with an extension cable. Still the same. It's the board, or the code.

Downloaded and installed. Got this error: Error: M997: In-application binary "iap4e.bin" not found

I guess the firmware didn't install, yet the text said it did. I went and found the iap4e.bin file, then the firmware installed. Still no probe deployment. I've spent an entire weekend screwing with this...

What happens if you send the command to put the probe into test mode where it deploys and retracts repeatedly? Let it run that for a long time and see if it successfully deploys and retracts or if it gets stuck/fails.
What do you have in your homing files?
What do you have in the deploy and retract files?
What version of BLTouch is it? Clone or genuine? -
@Phaedrux
The BLTouch is a genuine v3.0. Here are all of the files you requested, plus config.g. Thanks!; homeall.g

@BearcatTD
thanks for posting your config files. I too have had lots of problems getting BL touch (classic) to work.
it turns out the docs say not to use deploy and retract probe.g files
but when i added those files, it started to work.
the trouble shooting doc is confusing, 1 line says do not use in new firmware, the next line says be sure to have them.
either way, now i'm off to tweak. just want to say thanks for sharing."Don't use M98 PDeployprobe.g The old way using probe type 5 required you to use M98 PDeployprobe.g and M98PRetractprobe.g to deploy and retract the pin. Type9 now handles the deployment internally. If you need to manually deploy and retract, use M401 and M402, respectively."
"Double Check Deployprobe.g and Retractprobe.g Make sure your deploy and retract macros located in the sys folder are configured correctly. " -

"Double Check Deployprobe.g and Retractprobe.g Make sure your deploy and retract macros located in the sys folder are configured correctly. "M98 PDeployprobe.g means running the deploy file as a macro. That's not recommended because then the firmware doesn't know what state the probe is in. The deployprobe.g file still needs to exist and have the M280 command in it, you just shouldn't manually execute it. Let the firmware handle that part. It will deploy and retract automatically when using G30 or G29.

M98 Pdeployprobe.g ; deploy mechanical Z probe
M98 Pretractprobe.g ; retract mechanical Z probeRemove those from your home all file. Let the firmware deploy and retract the probe automatically.
Still curious to see the results of putting it in test mode for a while.

@Phaedrux Thanks!
I deleted those two lines, power cycled the printer and everything has been working fine for the last hour or two. But, alas, that has uncovered another problem...LOL...see new post!
Thanks again for everyone's kind suggestions!

@Phaedrux appreciate the follow up. the wording still seemed confusing to me. perhaps they will update the docs to be more specific with the requirement. also thanks for the tip on removing the unnecessary lines, all is working well now.
