"Error: Probe was not triggered during probing move"

In fact, when it hits the bed I get a "1000" reading in the Z-Probe section of the dashbord, which is the normal reaction when something hits the nozzle:

But it stops inmediately, goes up a few cm and again I got "Error: probe was not triggered during probing move"

@ignacmc ok, that shows that the probe is working correctly so there is something odd happening in your probing file or configuration.

Looking again at config.g I see:

G31 P500 X0 Y0 Z2.5

Which to me does not make sense, the smart effector triggers at Z0 or possibly Z-0.1 or something like that to indicate that it will go slightly past Z0 as its triggering. it can't trigger 2.5mm above the bed.

Change that line to

G31 P500 X0 Y0 Z-0.1

I see from your first post this used to be a Z-0.172 so the configurator version is for a generic Z probe, not the smart effector.

also check your config-override.g, potentially for testing comment out the M501 in your config.g

@T3P3Tony First of all, thank you very much for your time.

I have done the change you suggested to G31 P500 X0 Y0 Z-0.1

But I keep having the same Error when I do a G30. There is no "config-override. g" since I deleted the existing one and have not issued a M500 yet.

This is really driving me crazy...Any clue of what can be happening here?

Thanks in advance

@ignacmc is the Z0 being set correctly despite the error by the probing move?

ignacmc

@T3P3Tony You mean by jogging the nozzle down until touching the bed or gripping a sheet of paper and then issuing a G92 Z0?

T3P3Tony

@ignacmc I mean jogging the nozzle down and seeing if Z0 is infact at the bed (you can use a sheet of paper as you suggest to test this, accounting for the paper thickness it should grip a little above Z0.

I am not suggesting that you G92 to set Z0 at that point as a solution, just trying to get o the bottom of this because I have a quite similar setup to you on a delta printer a do not get the error at all.

ignacmc

@T3P3Tony Ok. First I have disabled axis with M564 S0, then I jog the nozzle down til it grabs the paper on the bed. Reading the display it says I am at X0 Y0 Z-9.92

In my config.g I have:

M665 R227.445 L440.718 B185 H420.232

I can't remember where this H420.232 came from, probably from a Delta Calibration long time ago. Should I add 9.92 to it?

Yesterday I tried with H450 without any success...

T3P3Tony

@ignacmc Ahh thats interesting, so the H value may be wrong - maybe that was from the set of config you generated recently. what was the H value before that?

What i meant for you to do was:
Home the printer

Send G30 for a single probe.

then jog the nozzle down to see what height Z0 corresponded to.

ignacmc

@T3P3Tony Ok. done exactly as you asked me to do: First G28, then G30 and the nozzle hits the bed, gives me the same error again and it goes up to Z 29.90. jogging it down to Z 0 it is still like 10mm above bed. See photo at Z=0

T3P3Tony

@ignacmc ok for now set the H value in M665 to 435 and try again.

once this is working, you will need to run delta calibration again anyway.

Are the other M665 parameters correct, e.g. R and L?

ignacmc

@T3P3Tony Yes, I had tried with higher H before without success. Now I have just tried with:

M665 R227.445 L440.718 B185 H435

I believe that R, L and B are correct for a Anycubic Predator

Error keeps happening

T3P3Tony

@ignacmc ok so with the higher H, go through the steps again:

home the printer

send G30

then jog down and see where Z0 is

ignacmc

@T3P3Tony OK, repeating all process with H435 in M665. G28, then G30, touch bed, Error again and now after hitting bed it goes up to Z29.90, jogging down manually, the paper gets gripped at Z4.80 (positive)

T3P3Tony

@ignacmc ok this is progress, in the sense its now behaving as expected, other than the error.

@dc42 any ideas?
