Yeah, I gave up on BLtouches. Always having to adjust stuff, even though you shouldn't need to.

Put a Tap on it. Or klicky probe. Or...hard mounts, adjust once, and forget it. The Tap you won't ever need to adjust your z if you change nozzles. I've seen some on bedslingers.

You look like you got it going pretty good now. Don't do like I do and leave it in pieces because you'll get to those other things while you have it apart...I have a few just sitting around in pieces still.

I am happy to say that I got my original BL Touch to work. After reading through tons of Reddit posts (more on that later) and watching countless videos without a solution, I finally stumble upon a solution in Marlin. Apparently, if you have V3.1 Bltouch and supply it with 5V, on some printer/controller board, you need to tell it that it needs to output the 5V for the logic. I had an idea, maybe it is the same way in Klipper. Guess what, there it was. At the very bottom in the Klipper docs under BL Touch, there was a paragraph. I must have read this and brushed it aside because it did describe to do this if you have this problem. My rant if over. Let me layout my problem and the solution for future viewers who has the same issues.

Quote from Klipper docs for initial test:

"The next step is to confirm that the sensor pin is working correctly. Run BLTOUCH_DEBUG COMMAND=pin_down, verify that the pin moves down, run BLTOUCH_DEBUG COMMAND=touch_mode, run QUERY_PROBE, and verify that command reports "probe: open". Then while gently pushing the pin up slightly with the nail of your finger run QUERY_PROBE again. Verify the command reports "probe: TRIGGERED".

If you trigger the probe but the query keeps on saying "OPEN", then your controller board is likely not recognizing the logic due to the BL Touch not signaling with 5V. Make sure your motherboard can accept 5V logic signal.

For V3.1, you enter at the console the following


For V3.0, you need to set it up every time on boot up. Add the following line in the "printer.cfg" file under the [BLTOUCH] header



A little bit more ranting, there is absolutely no good 3D printer forum. At least the ones I have been on. Reddit is basically it. Which is not the greatest format for this kind of stuff.

TH3D has a discord channel, post in the hardware or firmware sections and I’d be that @LookItsRain would answer quickly with correct answers.

Thanks. Getting instant answer is nice, but one of the problem with the discord format is the information is no longer around afterward. Anyone after me have to ask the same question, and someone else has to give the answer over and over. Discord was going to be my last resort if I could not get it working.
