BLTouch wiring #3

Closed codedmind closed 4 years ago

codedmind commented 4 years ago

Hello, can you explain the bltouch wiring... i'm using until now the servos and the z-index to using the bltouch but you refer to use servo and probe?

I'm using this https://camo.githubusercontent.com/56b380ce77969d6bf7e4d627094676b2625dc876/68747470733a2f2f692e696d6775722e636f6d2f42524a516e65392e6a7067

I'm not sure what to explain. My README is fairly clear. Just connect the BLTouch to the PROBE header as opposed to the Z-STOP. SERVO remains unchanged, same in both cases.

pmjdebruijn commented 4 years ago

If you have a clear defined question, I'd be happy to answer though...

codedmind commented 4 years ago

@pmjdebruijn sorry if i'm not able to explain... the wiring you say in the readme is like the picture i share? In the pic the five pins from bltouch go like this 3 pins go to the servo and 2 pins to the z-plug but you refer

Your readme refers to servo and probe.... is your "probe" the zplug or is other pins in the board?

pmjdebruijn commented 4 years ago

My README explicitly states the Z-STOP is ignored. So I'm not sure why you're confused about this.

Directly next to the SERVO header, there is a header clearly labeled as PROBE, as is referred to by my README.

As for the exact wiring, that highly depends on where you got your BLtouch from, cross-reference the SKR mini E3 board documentation with the pin labels on your BLtouch.

@pmjdebruijn ok thanks for clarify that. Like i said i see that wiring scheme that is the same as the teaching tech if i'm not wrong, and used it that way (using the z-stop) so apparently the bltouch could be wiring in two different ways :/

pmjdebruijn commented 4 years ago

Indeed.

The PROBE header is specifically intended for the BLTouch, but all boards have this luxury.

Connecting the BLTouch to the Z-STOP is essentially a workaround for cost-reduced boards (like the Creality Melzi) that do not have a dedicated connector for it.

I've left the original Z-STOP micro switch connected, so I can flash back to a non-bltouch firmware at any point, and the Z-STOP micro switch will just work again as normal, without having to do any rewiring.

ik heb deze https://www.amazon.de/gp/product/B07Y4DXNNN/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 maar de draden zijn anders van kleur is origineel zeg maar moet ik hier ook de draden omwisselen

pmjdebruijn commented 4 years ago

As I've already mentioned above, you should cross reference the markings on your BLTouch PCB with the documentation of your specific board.
