I agree, that's very odd behaviour! Auto calibration is saying that it made matters worse.
Please restart the Duet, connect a PC running Pronterface/YAT/etc. via USB, send M111 S1 P4 to enable Move debugging, then run auto calibration. Report the debug output from the PC here.
-
I'll setup terminal and get back to you.
I deleted config-overide rebooted and ran auto calibrate again
This is the result
Calibrated 7 factors using 7 points, deviation before 1.030 after nan
One more tidbit, I was successful performing multiple Auto Calibrations using a BLTouch clone. I stopped using it since it had inconsistent results, (thats why I bought the DUET IR)
I believe I was on 2.02RC2 but not sure. -
I have one other report of auto calibration producing 'nan' values. I believe these are generated when one or more probe points are not reachable using the current M665 parameters (even when one set of arms becomes horizontal), typically because the delta radius has been set incorrectly, or simply because when the bed.g file was generated, the probing radius was set too high (taking account of any XY offset of the Z probe). The debug data may confirm that.
-
When you said ". Report the debug output from the PC here" is that from terminal?
YAT is not displaying much.

I've been successful with the Delta Parameters that I've been using for some time. They deviate only slightly from manual calibration.
I tried a new bed.g probing set using 80mm probing radius. same result.
The IR Board is positioned Y-21 (21mm In front of the nozzle, with z tower to the rear). (hopefully I have that correct)
-
When you run auto calibration, it should produced a lot more output.
-
is there a parameter setting in YAT?
I've tried multiple times same result.
-
I swapped IR boards (Since I don't know what else to try and I have a spare), same results.
I did manage to get the diag info using Pronterface

I looked through the diag data and I don't know what I'm looking for and I really can't make sense of any of it.
I've tried all that I can, I keep getting erratic results. Really far out numbers.
Before:
Diagonal 268.000, delta radius 138.000, homed height 316.200, bed radius 110.0, X 0.000°, Y 0.000°, Z 0.000°Calibrated 7 factors using 7 points, deviation before 0.833 after 0.880
After:
Diagonal 621.396, delta radius 205.951, homed height 316.909, bed radius 110.0, X 5.334°, Y -1.442°, Z 0.000°I'm going to manually calibrate so I can get it back in service.

@bricor said in Auto Delta Calibration Odd Behavior:
is there a parameter setting in YAT?
I've tried multiple times same result.
Ah I see the problem. YAT isn't recognising LF as the line ending character, so it's putting everything on one line, and truncating it. In YAT, go to Terminal/Settings/Text Settings and change the EOL sequence to <LF>.
-
The data looks to be about the same as I posted from Pronterface. You might have missed my posts after the YAT question.

The matrix is numerically unstable (the diagonal element of the last row of the solved matrix is showing as zero). Try 6-factor calibration instead of 7. That's S6 on the final G30 command in bed.g instead of S7.

6 Factor seems to have made it work
I ran the calibration and it was finally successful running multiple passes. The printer is cold and in need of a full calibration (i gave up last night/early am in the middle of manual calibration) but the results are good.

That's looking much better!
-
Is the answer to the issue, don't use 7 factor?
-
Yes, we don't recommend 7-factor calibration unless you can probe a lot of points including some that are between two towers and outside the normal print radius.

Thank you for your help once again. Issue solved.
