G32 Error: Probe was not triggered during probing move
-
Hello Community,
I am new here in this forum. Hopefully someone can solve my headache here.
I run a core xy printer with a duet3
Bed on 4 ballscrews.
x and y axis home with microswitch...... no problem
z axis should home with a npn probe. I also try BL Touch same problem
I can homeall anywhere on the bed. But I run G32 and the bed stops about 10mm before it gets to the probe
and I get

How far from the bed was the probe after moving to the center of the bed?
The "problem" with homing X and Y without first homing Z is that they do that relative G1 Z5 move but where Z ends up depends entirely on where it was when the homing started.
The probe can end up to far from the bed for probing to complete, based on the probe settings.
Which is why I fit all of my printers with a Z endstop sensor so I can first home Z, then X and Y and when it comes time to probe the Z position is known and can be set according to the needs of the probe configuration.

home z then y and moves to center on bed to home z. I have a[so move z to the corners and z will home at any of them. But will not run G32

Less than 10mm form bed

Have you been able to do just a plain G30 and have the probe work?
Frederick
-
Yes in homeall it works fine
-
In your first post you mention that the bed stops about 10mm away from the bed.
Given the dive height and trigger height settings of your probe I'm not really surprised.
Since the printer is fully homed before doing a G32, try adding a command to move to Z=10 at the start of the bed.g file.
Let us know.

After the G23 S2 I put G1 Z0 F100 the bed move to zero then it move to 11.75 Z and moved to the first P0 point.
how did it get Z11.75? -

What is a G32 S2?
how did it get Z11.75?
At the start of a probe the position on the Z axis is set at the probe Z Trigger Height (in your case 6.75) plus the Dive Height (in your case 5), thus the 11.75.
But the firmware should have no problem probing from that Z position unless something is preventing the probe from getting to the Z position where it triggers.

I mistype G29 S2
Ok I see the 11.75 now
it works with G30 but not G30 P0 X20 Y20 Z-9999 -
I took the 6.75 to 0 and the H5 to H3 and it trigger but
Error: Some computed corrections exceed configured limit of 1.00mm: -1.892 -2.778 -2.358 -2.208
Can I set the range to a larger number -
You need to add the S parameter to your M671 command to give it a tolerance for adjustment.
-
Thank you for you Help. I will try that tomorrow
I still do not see that it has to be that close to work? -
You cannot just set the Z Trigger Height parameter to any value. It has to be the actual height above the bed that the probe triggers.
I think you have an inductive probe and it's trigger height might be in the range 2mm to 4mm.
Did you calibrate the probe to determine the Z Trigger Height parameter as accurate as possible?
