Hi @dc42.
Yes, I followed the exact directions found in the documentation for "Measuring Trigger Height" here. Yet somehow, I received all sorts of values from measuring the same dead-center spot.
I'm wondering if my printer is in the Bermuda Triangle.
I'll change the M558 F value to F200 tonight.
Thanks @dc42

@mindbender9, please clarify what type of Z-probe you are using. I was assuming it was my own IR sensor, but skimming through this rather long thread, I found user @3mm mentioning the IR sensor but no confirmation that you are using one too.
Hi @dc42 - The IR sensor that I'm using is the "Mini differential IR height sensor" - I believe this might be one that you designed.
It is currently mounted on my hot-end with an offset of 32.82mm (distance from the nozzle).
@dc42 said in Beginner Needs Help - Anycubic Kossel Plus + Duet WiFi -- HOW?:
- Is the variance is between probing at different points?
All points were for the same position. Dead center, at the middle of the bed.
Inconsistency in the trigger height for the IR sensor can also be due to using a transparent bed surface (e.g. glass or PEI) that is not backed by a black surface, or that has scuff marks on the top.
Using a replacement black bed top from the manufacturer.
- If your initial delta parameters are a long way out, that could cause probe points to be outside the bed limits. Try a smaller probing radius. You can always move some of the probe points further out when you have it working.
Will do. I’ll reduce the quantity of probe points using the wizard and see what happens.
Question for @dc42 - What should be entered for G31 in the bed.g file? Should the XYZ values match the config.g G31 line or should they be zeroed out?
So I performed a number of Trigger Height measurements tonight and only two of the ten tests were even close. I don't understand why there's such a variance between the numbers.
Z-Height #1: 2.377
Z-Height #2: 3.953
Z-Height #3: 2.641
Z-Height #4: 3.09
Z-Height #5: 3.391
Z-Height #6: 4.415
Z-Height #7: 2.103
Z-Height #8: 3.628
Z-Height #9: 3.653
Z-Height #10: 3.516
Now, two of the Auto Calibration points land outside of the bed. And I'm unable to change these outside positions no matter what G1 Xx Yy Z99999 H0 values I save to the bed.g file. It's like the board isn't reading the bed.g file. What happened?
What do I do now?
@dc42 said in Beginner Needs Help - Anycubic Kossel Plus + Duet WiFi -- HOW?:
Measure the IR sensor trigger height and use that value in the G31 Z parameter instead.
Edit: I'll go over the "Measuring the trigger height" section of your instructions when I get home. Thanks!
One other question:
G31 X0 Y0 Z20
While the config.g line has:
G31 X0 Y-32.82 Z0 P500
Question: Should the two G31 lines match in both files?
Thanks for your help!
Terrible results when I try to print.
Good News: I've taken care of the Z-probe setup. I changed the bed.g file settings to only use three calibration points and it worked. So I went back to the 10-point settings and changed any that went off the bed. When I click Auto-Delta Calibration, all 10 calibration points now complete successfully - the nozzle comes within 0.2mm of the bed, the Z-probe LED flashes and the nozzle retracts then goes to the next point. I have placed the M500 code at the end of bed.g and M501 at the end of config.g.
Bad News: Whenever I upload a gcode file of a 0.2mm test circle (after performing a calibration prior), the nozzle buries itself hard into the bed. Every time. And while I am not fast enough to power off the nozzle (it's dropping that fast), I think I'm at my last ropes here. I'm attaching whatever config files I have at this point.
More Bad News: The Duet Wifi web interface keeps disconnecting when I open the webpage in either Google Chrome or Microsoft Edge. It takes 30 seconds or more to allow me to reconnect, or I have to manually restart the board.
Question: Why does the nozzle bury itself into the bed when I just auto-calibrated the printer a few seconds before? Why is there a height difference that puts the Z-position below the bed after the auto-calibration?

Edit: Hi @dc42 - Changing the Y-value did not change anything with the nozzle. The hot-end/IR probe went to the same position as it did on previous attempts. No change.
@danal said in Beginner Needs Help - Anycubic Kossel Plus + Duet WiFi -- HOW?:
Try a radius of 105, for diameter of 210, to keep things well away from the edges. If that works, you may be able to raise it slightly, watching for the edges. To start with, something like
M557 R105 S20
Hi @Danal,
I changed the M557's R value to R105, R90 and R80 but the third stop of the autocalibrate still ran into issues (regardless of the R-value the was set).
With R105, it looks like the IR probe is just hovering outside of the edge of the bed, while the nozzle is inside the bed area. When I started lowering the R-value, the IR probe position didn't change. Here's a picture:
So it looks like the IR probe doesn't see the bed and keeps dropping, while the nozzle is inside the area of the bed, and this ends with nozzle contact as a result. And lowering the R-value doesn't not change this position.
I think we're close, but the nozzle's refusal to reflect any of the R-values is odd.
Hopefully, you'll be able to recognize something from these pictures.
View from front between X and Y motors:
View from right side between Y and Z motors:
View from left side between X and Z motors:
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.
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?

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
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?

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
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)?
@dc42 said in Beginner Needs Help - Anycubic Kossel Plus + Duet WiFi -- HOW?:
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.
Ah ok. Thanks @dc42 - I'll reterminate the wire when I get home.
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:

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!

Having said that, I would NOT take your machine apart again.
LOL - No argument here.
And, just checking basic assumptions: You have M665 L271, correct?
Yes, config.g still has M665 L271 set. I'm working on the bed issues and will remove the stock bed mounts and pursue the direct attached method.
Thanks for the help! I'll start up a test print when I get home from work.
@juice - How long has it been since you've purchased the AC Kossel? If it's still under warranty, you could pursue getting a replacement part for that single arm.
On second thought, trying to get tech support from Anycubic3D wasn't easy. You might have better luck going through the seller for a replacement part under warranty.
Otherwise, several people have recommended carbon fiber aftermarket arms/ball ends as being one of the best upgrades for a delta printer. When I get my printer to work, I might look at replacement arms as a future purchase.
Hi @Juice
If you mean the arms, I disassembled them from the Nozzle/Hot-End and the slider assemblies. Then I measured each using a ruler, and they were all uniform in length.
But I more or less used your diagram (thank you for that) and eyeballed to center position in each eye.
Getting the arms reattached took a little work.
Measuring Eyehole to Eyehole, the arms are 270-271mm in length.
@3mm - You were right on the money regarding the floating nuts. I was able to reattach all of the arms after removing the sliders like you mentioned. Thanks again.
@Danal - I set all three sliders and endstops to the same position equally. One slider arm was slightly off by 1mm compared to the other two, but now they're all evenly set.
I want to recheck the three main pillars again before performing a test calibration. Just to be safe.
Thanks guys for all of the help. Believe me, I am very grateful for all of the tips and direction you're sending my way. I would be (more) lost if you guys weren't jumping in to help.
Much appreciated as always!
