G32 Error:´´ Z probe was not triggered during probing move´´

Hi,

Comment out everything in bed.g and add this M291 P"BED.G" R"BED.G" T0

From the DWC execute a G32.

You should get the popup message generated by M291.

As to the probe working sometimes and not others I would think perhaps the probe needs adjusting or the wiring is being affected by motion due to a bad crimp or almost broken wire.

like this?

what do you mean with execute a G32 in combination of M291?
sry english is not my mother tongue. to be clear I have to aks. I had to long time problems with the BL.
Wiring should be fine.. is not the biggest deal at the moment.

Hi,

English is a problem - understood.

OK what I want to be sure is that bed.g is executing and nothing else is happening causing the G29 issue.

So I would like you to have in your bed.g file JUST the following - you can delete or comment out everything else

M291 P"BED.G is running" R"Click to exit" S1 T0

Invoking G32 from the Duet Web Control (DWC) should run bed.g and you should see the popup message and nothing else should happen.

As to the height map when you created it using G29 did you first do a G30 ?

The purpose of the G30 is to allow the firmware to determine exactly there Z=0 is.

@fcwilt english is fine but especially person from the US or Australia uses expressions which I haven´t learned in school. I have to practice!

As to the heatmap.... I made a G32 but the Duet made a G29.
Before I made a nomral G30.
I know about G30.

Invoking G32 let the nozzle move to the first probe point of a G29 command. So the Duet makes a G29 instead of G32. How can so many things be wrong

@fcwilt
how can I make a G32 when my bed.g file isn´t there anymore?
I thought the software is calculating the high of each probing point in raleation to the leadscrews...

Hi,

I want you to have a bed.g file but I only want it to contain the M291 command, for now, just as a test.

You invoke it with G32 which is access from the Duet Web Control (DWC) on the Dashboard, using the "Compensation and Calibration" drop down menu.

Once I am sure that nothing other than beg.g is running in response to G32 then we will insure the normal commands for auto bed leveling are back into bed.g and the M291 is gone.

That's why I said you can just comment everything else out and add the single M291 command. Commenting the other lines out will allow you to restore them just by removing the comment character.

ok I understand!
so what can I do for the next steps?

Hi,

You mean after I'm sure that bed.g is running and nothing else unexpected happens?

Frederick

@fcwilt
to fix my multiple problems...

@barbarossa-cologne

Hi,

I am focusing on just two problems right now.

Making sure the probe is working.
Making sure bed.g is working.

Anything else you want to work on?

Frederick

dutti

@fcwilt
Probe is working.
I don´t know what I have to change in my bed.g file...
you told me you wanna make a test. So I did it.... and now?
I made a G32 and it´s doing a G29. Why?
I just wanna make a 4 point true auto level.... thats the last thing I have to do before printing. SOS

Hi,

When you did the G32 did you see the popup message saying beg.g was running?

drives to the first probe point of mesh compension and --> g32 -->

only this message came

And this was with bed.g only having the M291 command?

Frederick

@fcwilt yes

@fcwilt yes

And you didn't see the popup message about bed.g running?

Frederick

@fcwilt no. just the message you see on the screenshot.

Hi,

Do you know how to enter commands directly into Duet Web Control using the Console page?

Frederick

@fcwilt yes
