1.21RC2 (2018-02-15 build 2) installed it some time in june
Ok that is quite old firmware. You should definitely update.
Many things have changed since that version and your config files would require quite a few changes. It may be easier to simply use the web configurator to generate a new config set and then update the firmware along with it.

IF you would rather wait to update the firmware and get the bltouch working first, please respond to my questions from the previous post.

Ok. so far nothing has happened when i home the xyz axis.

if to be honest, the first time i updated the firmware, it was quiet a hassel, but if nothing helps i gues i have to do it from scrach again. last time i did it, it took me a whole day reading and downloading and following instructions all at the same time. gues i try it tomorrow.
thanks for the advices . just in case i ask, is ther a alternative for this problem. like a quick fix or something... need some prints to make. -

servo control is in pin 7
Ok if you're using pin 7 then a few things need to change.
in config.g instead of this
M307 H3 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch M307 H4 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouchyou need this:
M307 H7 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouchAnd in deploy you need this
M280 P7 S10 I1And in retract you need this
M280 P7 S90 I1And you need to make sure that if you have a config-override.g file that any M307 H7 commands in it are commented out.

I understand completely. The firmware update process around that time frame was a bit challenging, but since version 2.0 it is generally much much easier and all you must do is upload a single zip file.
If and when you want to update the firmware just post again and we can work out what the easiest path would be since any update for you will require some config changes as well.
-
all right. try this out tomorrow and send feedback of the results here in this thread.
-
dang... i feel like some kind of releaf. thanks a lot... 3d printing community is a special place to get advice and help. thanks a lot mi8.
-
Yeah tried the easier way but no results.
some how in retractprobe.g
M280 P3 S90 I1
gave me an error message -
@4thddoughnut please use the same P like for deploy, P7.
-
tried it allso out... no results

Hi,
I don't have the I1 parameter in my BLTouch control macros.
I have no idea if it could cause problems but it doesn't seem to be required.
As to it not working perhaps you are connected to the wrong pin?

@4thddoughnut maybe we should clarify first to which firmware version you updated: 2.05.1 or 3.1.1? From the version depends which syntax for the config is necessary. Please repost the content of your config and homeall again, to know the current setting.
Please tell where you connected the BLtouch wires, so the correct config can be checked.
If you run
M98 P"config.g"
you can make a first check whether the syntax of the config is ok. -
Perhaps a photo of how you have the BLtouch wired would help us know which pins you are actually using.

did today my firmware update. but now i got a new problem.
-
@4thddoughnut which problem?

Good job on updating the firmware. I few things to consider.
First, your version of DWC has not been updated yet. I think you will need to do it manually because it's too old to auto update along with the rest of the firmware.
Pull the SD card and use your PC to replace the contents of the existing /www/ folder with the contents of this zip file.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/DuetWebControl-SD-2.0.7.zip
As for your video, I'm not sure what I'm looking at. What is on the bottom of the BLtouch pin?
Can you please post your current config.g and homing files. Several changes will be required along with the updated firmware.
-
@4thddoughnut if you're confused about the retract at the end of the video, it's the line M98 Pretractprobe.g in homeall. But as Phaedrux said, please post the file and let us view over it.

its a temporary repai >D the tip of bl touch has broken off. and i have mutch greater problem to deal with... doesn't have the tool tip have to be just above the built plate... cuz when i did the z probe callibration, insted of thickness of the paper witch was about 0. something. it showed me after G30 S-1 2.15 mm wtf?

@4thddoughnut said in BLTouch Z offset of the toolhead does not change on duet 2 wifi.:
M558 P5 H5 F120 T6000 ; Set Z probe type to bltouch and the dive height + speeds
In config.g This should be:
M558 P9 H5 F120 T6000In all of your homing files you should change the S1 and S2 to H1 or H2.
example:
G1 Z2.5 F6000 H2 ; lift Z relative to current position G1 H1 X-269 Y-261 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)Also, remove this
M98 Pretractprobe.g ; retract mechanical Z probeAnd this
<G1 S1 Z-265 F1800 ; move Z down until the endstop is triggered G92 Z0 ; set Z position to axis minimum (you may want to adjust this)
