Duet 2 Wifi - TRONXY Z Probe Woes:

Veti

when the M558 is in the config. what is the output of M558 without parameters
What is the output of M119 when its not triggered, when its triggered? post your config.g and homing files.

xxexx

THX, i really appreciaty your help!

untriggered: M119
Endstops - X: not stopped, Y: at min stop, Z: not stopped, Z probe: not stopped

Triggered: M119
Endstops - X: not stopped, Y: at min stop, Z: not stopped, Z probe: at min stop

You have two M558 commands in your config

you have a commented G31 line. This needs to be uncommented.
also the P Value is to large. It ranges from 0-1000. Try 500.
Dont forget to calibrate the Z value afterwards.

Your thermistor values are most likely wrong. B4138 is the default and need to be replaced with the correct values of your thermistors. Find out what thermistors you are using and look up the beta value.

Thanks for the fast reply - will check ASAP

Same result - after uploading the new configuration.zip, the board does not show z probe activation. If i put in "M558 P5 I1" manually via the gcode window in the Duet web Control it works - it shows when the probe is triggered - but the z homing still does not stop even when the probe is triggered.

I have no idea.

@veti said in Duet 2 Wifi - TRONXY Z Probe Woes::

what is the output of M558 without parameters

please answer this question.

xxexx

M558
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

xxexx

if i activate the probe via "m558 P5 I1" and the sensor is not triggered it says:

xxexx

M558
Z Probe type 5, input 0, invert yes, dive height 5.0mm, probe speed 120mm/min, travel speed 6000mm/min, recovery time 0.00 sec, heaters normal, max taps 1, max diff 0.03

and if it is triggered:
M558
Z Probe type 5, input 0, invert yes, dive height 5.0mm, probe speed 120mm/min, travel speed 6000mm/min, recovery time 0.00 sec, heaters normal, max taps 1, max diff 0.03

So i guess my problem is "input 0"

if i activate the probe via "m558 P5 I1"

before you manually put in that command

xxexx

If i restart the board (sensor does not show red "1000" when triggered:

M558
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

Veti

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

xxexx

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).

Veti

@xxexx said in Duet 2 Wifi - TRONXY Z Probe Woes::

I did exactly that

no you did not. please reread what i wrote.

xxexx

ok, now i deleted all M558 lines and manually retyped "M558 P5 I1", uploaded and restared - no change

xxexx

if i type the same command it works

My config.zip includes on "SYS" folder with all the *.g files.

Z-Probe
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

Veti

that is very strange. what firmware version are you running?

also please post your config.zip file

xxexx

M115
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

DocTrucker

I see some of these reports have a probe speed of 0 and others 120. That looks odd to me.

xxexx

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!

BR, Norbert
