Duet 2 Wifi - TRONXY Z Probe Woes:
if i activate the probe via "m558 P5 I1"
before you manually put in that command
If i restart the board (sensor does not show red "1000" when triggered:
Z Probe type 0, input 0, invert no, dive height 5.0mm, probe speed 0mm/min, travel speed 6000mm/min, recovery time 0.00 sec, heaters normal, max taps 1, max diff 0.03
there must be something wrong with the lines you put in. Maybe hidden control characters
please delete the existing M558 lines completely and retype the M558 P5 I1 command by hand into the config.g. and check with M558 after restarting
I did exactly that - i commented the old m558 command and pasted "M558 P5 I1" into the config.g. Then i packed it into a new config.zip and uploaded it + restarted the board: sensor cannot be triggered.
Then i pasted and send "M558 P5 I1" manually - it works. (sensor lights up in the web configurator).
I did exactly that
no you did not. please reread what i wrote.
ok, now i deleted all M558 lines and manually retyped "M558 P5 I1", uploaded and restared - no change
if i type the same command it works
My config.zip includes on "SYS" folder with all the *.g files.
M574 Z1 S2 ; Set endstops controlled by probe
M558 P5 I1 ; Set Z probe type to unmodulated, the axes for which it is used and the probe + travel speeds
G31 P500 X100 Y100 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X15:15 Y15:315 S20
that is very strange. what firmware version are you running?
also please post your config.zip file
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.02(RTOS) ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2018-12-24b1

I see some of these reports have a probe speed of 0 and others 120. That looks odd to me.
Ok, so now i deleted all files from the SD card and reuploaded all files from the Wiki. -> Sensor was found!
Then i just had to reinsert M558 P5 I1 etc. and it immediately worked.
So it seems that my file structure was wrong and that was the problem.
My distant friend, i would like to thank you for your help and patience - guys like you make the internet great!
