Okay so I’ve been using the builder to help configure my setup as stated in the title I’m using an ender 3 printer, the V4.2.7(silent board) + bltouch. when I input the settings I think I need:
xbedsize 400
ybedsize 400
zbedsize 490
(i have the ender extender kit installed)
Bed levelling probe: (I’ve turned on)
- Use-zstop port for Probe
- Use probe for z homing
bed levelling method:
- Bilinear Bed levelling
levelling options:
- Add LCD levelling menu
- enable probe offset wizard
I then click build, wait and its successfully built. Great! I put the .Bin file on the sd card, plug it into my new v4.2.7 board, the bltouch deploys, retracts, deploys, retracts (lights up) I got to bed level and the bltouch doesn’t deploy, I go to auto home bltouch doesn’t deploy, I got to the bltouch settings where you can deploy, stow, test all manually and nothing happens.
what am I doing wrong?
my build reference is: 1E3F3A8C-6F7F-11EB-980B-E90D44A4798F
Has your BLTouch ever worked? The power on self test seems good – but it may well be an incorrect wiring setup.
Double check the wiring against the Ender 3 V2 FAQ (same mainboard) and confirm that the 3 pin cable you have is in the right order on your mainboard. You can use the Z-Stop port if you want to for the black / white cable.

There’s only really two failure modes for the BLTouch:
1) It doesn’t deploy – normally the 3 pin cable is wrong, or
2) It doesn’t detect contact – normally the 2 pin (black/white) cable is wrong.
yeah, the bltouch worked with my stock board v1.1.4
the link you have doesn’t seem to work?
@kingkrumble Sorry – I keep forgetting that the forum software makes an invalid link!
Try: https://marlin.crc.id.au/faq/
then click on the Ender 3 V2 link and go to the BLTouch section.
