Beginner Needs Help - Anycubic Kossel Plus + Duet WiFi -- HOW?

I've decided to stick with my original rods since before i undertook the upgrade, the machine was printing good, 20 mm calibration cubes printed within 0.1 mm deviation, so i guess the small difference in that one rod isn't enough to make a huge difference in print quality.

Deviation is part of the story. Here's another part:

Bottom is stock AKL rods. Top is Haydn magnetic. Otherwise identical. Even same G-Code file.

Middle is a different experiment, not relevant to this discussion.

@danal The parts that i printed before i started my upgrade weren't as good as your top print but were much better than your bottom print, even better than the middle one. That was with the old trigorilla board, i have yet to do any prints with the duet. That said, i am sure that having those sweet magnetic arms would be beneficial, its just that if i can get good quality prints with the arms i have, i'll hold off on the upgrade until i have some money burning a hole in my pocket.

Ok, made my first print with the duet upgraded anycubic kossel. Looks pretty good to me. X & Y dimensions need tweaking though.

So more weird results.

I've attached the DC42 IR Sensor to the hot-end (effector?) and connected the sensor to the Duet following the instructions. I've changed my M558 P-value to P1 and followed the first half of the instructions on David's webpage for the IR sensor (Link).

• If I put an object right near the bottom of the sensor, the LED lights up solid. I take my hand away, the LED turns off. Nice.

• On the Duet device webpage, the Z-Probe value remains at a value of 280 no matter what the Z-height is. It fluctuates between 279-280, and that's it.

• With 12V power applied, I enter M558 P1 then I enter G31 P500 Z1.0 on the G-Console. After setting the Z-height manually with 2 sheets of paper, I raise the nozzle 5mm up as instructed, then G92 Z0 to set Z=0.

• Following the instructions, I enter G30 S-1 and the nozzle buries itself into the bed again HARD. Here's a screenshot of the Console:

• If I press "Home All" the assembly raises itself up to the top but doesn't click the end-stops. I then get an error:

G28
Error: G0/G1: insufficient axes homed
Error: Homing failed

Here's the config files:

Entering the command "G30 S-1" is hanging me up. I've tried to do an auto-calibration and the nozzle took a number of measurements in the air above the bed ranging from 3mm - 130mm.

Can anyone make sense of this? I have not resolved the bed angle issue yet, but this is something else entirely. Please help! Thanks!

On the Duet device webpage, the Z-Probe value remains at a value of 280 no matter what the Z-height is. It fluctuates between 279-280, and that's it.

That suggests that either you have connected the OUT pin of the IR sensor to the wrong pin, or there is a bad connection in that wire. It should be connected to the pin labelled IN on the Probe connector. That's the pin on the opposite end of the connector to the 3.3V pin.

[Danal]

Also, homing MUST work before anything else.

homedelta.g should have much larger values in the first G1 command larger than the physical printer, so that the carriages go all the way to the switches, something like

G1 S1 X400 Y400 Z400 F1800

Ah ok. Thanks @dc42 - I'll reterminate the wire when I get home.

Thanks @Danal - I'll update homedelta.g when I get home.

Is this related to why the "G30 S-1" command to bury the nozzle hard into the bed (when it shouldn't move the Z position)?

Very likely.

[Juice]

@mindbender9
I see your M558 H parameter is still set to 5. Change it to 30mm as suggested by dc42 a few weeks back. I crashed my probe into the bed a few times over before i found that post. I believe that H parameter sets the height the probe moves to before actually doing any probing. If 5mm takes the probe below the bed before probing starts, it will crash every time.
Have you tried doing a manual calibration without a probe again, just to eliminate any fussiness with probes for now? I gave up using my probe as it wasn't consistent enough, probably a result of the frequent bed crashes. Manual calibration was quick, easy and accurate enough.

[mindbender9]

All -

I've made the two changes as instructed:

M558 P1 X0 Y0 Z0 H30 F1000 T5000
G1 S1 X400 Y400 Z400

Progress so far:

• The auto probe calibration works with the Z probe except for the far XY edge where it drags along the bed (the IR sensor is positioned off the side of the bed - it sees nothing so the nozzle eats the bed). This is amazing progress, though. Because reterminating the IR Z probe connectors got it to work (in theory).

• However, it looks like the printer still thinks that Z=5.3 is the same thing as Z=0. When I try to print something like the XYZ calibration cube, the nozzle drops down to Z5.30 (5.3mm above the bed) and spews filament onto the bed. Recalibrating (and entering M500 to save settings) doesn't resolve the issue. What might be causing this stubborn behavior in the printer?

Any suggestions? Thanks!

[Danal]

The probe is going off the side of the bed because your offset from the probe to the nozzle is set to zero.

In bed.g:

G31 X0 Y0 ; don't want any probe offset for this - ADDED 5/21/2018

and in config.g:

G31 X0 Y0 Z2.02 P500

The X and Y in G31 should accurately describe the distance from the probe to the nozzle.

[Danal]

As for Z 5.3, etc.

What is the physical offset of the probe to the nozzle in the Z direction?

G31 is telling the printer this is 2.02. Is it really? At the moment the probe triggers (like with your finger), what is the EXACT Z dimension to the tip of the nozzle, as compared to the probe?

[mindbender9]

@danal

Sorry for the delay, as I’ve been away for work.

You’ve asked “What is the physical offset of the probe to the nozzle in the Z direction?” Do you mean that I should measure the distance between the Z-probe edge and the nozzle tip?

Thanks

[T3P3Tony]

@mindbender9 no the way to measure this is to move the probe towards the bed until the probe triggers. Then move the Z axis down further until the nozzle is just touching the bed (measure using a piece of paper as feeler gauge). Then you have the difference between the probe trigger point and Z0. The probe Z offset.

[mindbender9]

Ok, I'm getting confused about what values to put in the G31 line.

G31 X0 Y32.82 Z0 P500

• I measured the distance from the tip of the nozzle/hot-end to the circuit board of the dc42 IR probe, which came out to 32.82mm. I believe that the IR probe is off to the side of the nozzle along its Y-axis, because when I click on "Y-10", it moves in the direction of the mounted IR probe. Therefore, I'm entering "Y32.82".

• For the X-value, I'm not sure if the probe is offset along the X-axis. From what I can see, the probe lines up directly in the path of the IR probe. So I'm going to make a guess and leave the X value of G31 as 0.

• For the Z-value, there's a problem (of course). As I lower the nozzle to the bed, it stops at Z=0 and won't go any lower - but the nozzle's position is roughly 8-10mm above the bed - it won't drop any further. The IR Probe also is at zero at this same point, but will register "465" if I slide a single page of paper under it.

Why is the Z-axis stopping at 8-10mm off of the bed?

If you have mounted the IR sensor with the bottom edge of the board 1 to 3mm above the top of the nozzle as recommended, then it should not be triggering when the nozzle is 8-10mm above the bed. Please ask your supplier to replace the IR sensor.

David:
From his screenshots, I don't believe the probe is triggering.

Mindbender9:

You MAY need to up the M665 H parameter, and then allow auto calibration to give you a real value. H is currently 285, try 300.

Finger on the power button!! Stop it if it drives into the bed.

[dc42]

Good point, I didn't read his post properly. Yes, it looks like the H parameter may need to be increased.

@danal

I increased the M665 H parameter to 300, and then changed the bed.g G31 line to: G31 X0 Y32.82 to account for the IR probe distance from the nozzle. I then ran auto-calibrate.

While the nozzle didn't bury itself, it did move outside the bed on the third survey while auto-calibrating. Here's a picture to show what I'm describing:

Both the IR Probe and the nozzle are outside the circular bed/printable area. I stopped the auto-calibration at this point.

Any idea how to correct this? I think we're getting close.

Are you sure that the offset for the probe is in the +Y direction only? Looking at your pictures compared to how my effector is installed (as by the anycubic manual) the probe may need offsetting on both axis. Can you post a picture of your effector from the front (between x and y motors) of the machine so we can see it relative to the bed?

I also noticed that the config-override.g file you posted has no updated parameters in it. When you do get the probe measuring all areas of the bed properly and you do an M500 to save the settings, double check that the override file has been updated.

Oh, and since you've been having lots of crashes when attempting to print, before you start printing anything next time, manually lower the nozzle to different points on the bed to make sure that "zero" isn't above or below the bed.
