Auto-leveling using an Inductive Sensor

[jfkansas]

well if you have a problem with it then stick with what u do now if that works for you. those of us interested in using the feature will use it.

Lol, just trying to get what all this work does or does better than a mechanical switch. I'm all for a truly dynamic full auto leveling if it actually does what is says it do.

Good news, Flashforge today (27th August) confirm the connection as per the attached image will work.

Originalt80 you can test by sending the following g-code:
M280 P0 S10 ; sensor pin down
M280 P0 S90 ; sensor pin up

Thank you.

Originalt80 you can test by sending the following g-code:
M280 P0 S10 ; sensor pin down
M280 P0 S90 ; sensor pin up

Thank you.

gladly but can u suggest what software to use for sending the g-code?
i have the following:
ReplicatorG (included with prointer)
Simplify3D
Printrun-Win-Slic3r-03Feb2015 -- Pronterface
arduino-1.6.9-windows
Flashprint

as stated i am a newbie so if u can point me in the direction where i enter the gcodes to send it would help.. this is all new to me sorry. i will gladly test anyway i can

You need to connect your PC via USB connection to FFCP, then:
1. run Simplify3D
2. Click on Tools and select Machine Control Panel
3. Normally Simplify3D will automatically connect to FFCP, if not then click on the Connect button
4. Click on the tab Communication
5. In the dialog box next to the Send button (bottom of the page) type the g-codes
6. Click the Send button
You should see the BLTouch pin head go up and down when you send the g-code

sorry for the delay i did i per your instructions but the screen im simplify3d says "this printer only supports binary commands" and nothing happens

is there a way we could communicate via instant messaging possibly?

Apologies just remembered Simplify3D does not support ascii commands to FFCP, so you need to use ReplicatorG as follows:
1. Connect PC/Laptop to FFCP
2. Run ReplicatorG
3. Click File select New (this will ensure nothing is loaded)
4. Type the following g-codes:
G162 X Y F3000 ; home XY just to confirm FFCP is receiving the codes
G1 X-60 Y-50 E0 F1000 ; move the extruders back out
M280 P0 S10 ; sensor pin down
M280 P0 S90 ; sensor pin up
M280 P0 S10 ; sensor pin down
M280 P0 S90 ; sensor pin up
5. Click the second last icon from the left - connect option
6. Click the first icon on the right - build option that will send the g-codes direct to FFCP
7. A message may appear saying ReplicatorG doesn't recognize gcode M280
8. Click Proceed anyway

Hopefully you will see the sensor pin go up and down.

If it doesn't and the extruder moves, then I will need to get in touch with the BLTouch people about what g-code to use with Sailfish.

Found this g-code which you can try if the M280 P0 S10 doesn't work.
M300 S10 ; sensor pin down
M300 S90 : sensor pin up
