Reddit reviews BLTouch : Auto Bed Leveling Sensor / To be a Premium 3D Printer

I had this exact same problem with a recently purchased Ender 3 (not pro), following the same video by Teaching Tech. Using a Pin27 adapter board.

Here is the response I received from ANTCLABS:

> Thank you for your message and I am sorry for your waiting.
Please remove C7 at the control board as like at this link. https://www.antclabs.com/wiring3
Thank you and hope you to be happy with your BLTouch.

> Best regards,

Fortunately, I was able to get the latest Marlin 2.x working no problem and didn't need to hack away at my board. I'll pastebin my configs in a few and a checksum of the firmware zip I used.

Configuration.h ** mind the offsets here, obviously. Dunno what mount you're using. I've slowed down the probe speeds quite a bit too.

Configuration_adv.h

I'll put together a diff of the example configs and see what I changed.

Here are the diff outputs from the Marlix-bugfix-2.x version I used. Left (red) is example ender3 config I started with, right (green) are my changes to support BLTouch:

Configuration.h

Doesn't look as though I made any changes to Configuration_adv.h, same as the example ender3 one.

I suspect the thing that actually fixed my problem was the shiny new BLTOUCH_V3 stuff. I bought my BLTouch less than a month ago:

I got mine through Amazon.

an $8 inductive sensor also just plugs into the z-endstop, but you would have to solder the connection on yourself. https://www.amazon.com/URBEST-Detecting-Distance-Inductive-Proximity/dp/B01M1777XK

But if you want something plug and play get a BL Touch: https://www.amazon.com/BLTouch-Leveling-Sensor-Premium-Printer/dp/B01FFV2TOS

with all of these options you have to update and flash the firmware to enable and allow autoleveling.
