Ill Setup BLTouch using https://forum.duet3d.com/topic/7972/bl-touch-install-success
But the Offset will not be used the Nozzle always is more then 5mm over the bed.
Ill stored the M31 commands in config.cfg AND in config Override but if ill Use G1 Z0 after homing ist stay too high over the bed.

What is wrong?

Hi i got an Older Wifi Duet laying around and now wanted to use it.
Ill Tryed to Update the Firmware from 1.19 to 2.05 but it always wants the DuetWifiFirmware.bin that ill could find on GitHub.Can someone Point me hot to upgrade ?

Thats what the Interface is shown me now
Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.19 (2017-08-14)
WiFi Server Version: 1.19
Web Interface Version: 1.22.6

Ok ill leave the Duet Outside,Now i can See that due DUet Regonized that the Switch will be triggered, but the DWC dont Show anything once a green 1000 maybe the Endstop is bad for Measering or anything else?

No i got no Message, he goes around without Touching the Bed an gives me new M665 and M666 Values.Also the Highmap after there hes touching 2 points of 61

Ill tryed the Delta Autoclibration but ill Stuck.
The Point for Trigger High ill dont understand.
Ill Mount my Probe this here it has a high from 15mm untriggered Switch to Base.
When ill doit like it written here https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer Measuring the trigger height the Print in my case it 0.024.
Now ill Run Auto Calibration, but the Switch never Touchs the Bed also when il do after a G29.
After Calibration Z0 is far away from the Bed

Whats wrong?

Ok Works now, so one thing left, I got an Microswitch as Z-Probe Conected to E0,Test shows that is Triggered with a Value of 1000 an untriggered 0.If i use the Delta Calibriation ist does not Realize that the Siwtch is triggered,So whats wrong with him?An why Z-Probe in the WebInterface shows 2 Different Colors i ill play around with the TiggerValue for Z-Probe if i use 0-1000 its Red when Triggered und 1001-1024 is shows Yellow.

Ok so the Logic on the Duet Board has changed since 1.17 ok.Ill tryed also to connect to my home network but i only can see the Duet at AccesPoint when i user m552 s2 to check with m552 he told me Wifi Module reported error no known networks found Wifi Module is idle.Anything Changed also there?In the Doc ill found nothibg about changes.

I Installed my Wifi Duet into my Delta Connecting all wires.The Endstop LEDs on the Board are lighting without hitting the Endstops.
Try to Reverse the Endstop Using M574 S0-2 nothing works LED stop lighting when i Press the Endstop.
Using latest Duet2CombinedFirmware

Endstops are Mounted At Max.Heres my Config what i use for start up Setup:

So ill switch X and Y Motor Connection, but Printer Homes when ill say X Homing Y instead of X.
Any Idea?
