I'm the guy asking if this works for the duet on your video's comments. I can also help if need be.

M556
reference command:
M556 S100 X0.7 Y-0.2 Z0.6
"The S parameter is the length of a triangle along each axis in mm."

So we measured both 100mm and 50mm lengths, with your test. (will v4 average 50mm or 100mm measurements? I'm unsure how to use M556.

see my post above for the results

I have entered into the console:
M556 S100 x0.38
firmware accepts it
M556 in console - output:
M556
Axis compensations - XY: 0.00380, YZ: 0.00000, ZX: 0.00000

guess ill try with this

the following is a couple of manual g32's and then I ran you macro as well:

If already printed something
prepose adding to end.gcode is slicer
M84 S15 ;

So railcore will hold motor current for 15mins after a print.
Then no G32's should be necessary...
Heat steppers
Homeall
start new print

If cold printer, tram status unknown
Have macro determine if tram ie 1 g32
if yes - result below threshold > dont tram again > continue
yes - result above threshold > tram again > repeat if necessary
if no - continue

just ideas

My login to get new version no longer works??

@martink
Was the strangest thing. I know my harness was "fugazi", but if yours was legit. If it's something else like a power panic or buffer over flow I'll try the hard power reset next time.
Thanks for posting your experience. Felt like printer was trolling me,

@dc42

Must have been a wiring issue. I dont know really. Maybe it was the temp condition of my wiring job. Using servo wire that wasn't long enough, couplers, mismatched connectors, etc. Last night after re-hot gluing the connectors I still had an issue. Today at work I see your post m122 comment, come home and it works.

¯\_(ツ)_/¯

If i have issues in the future I'll wire a fully soldered custom wiring harness with no connectors in the middle.

Hey guys,

Great work here 1st off.
I'm having a strange issue. Last night I had over 10 successful tuning runs with this plugin. I was on my way to finding the best input shaper for my setup. Around the 12th or 13th run the plugin started crashing after the 1st X-axis move. When it crashes the dwc becomes frozen and an automatic restart is triggered, similar to if I had pressed the stop button. I have uninstalled the plugin and reinstalled it, still crashes. I've tried doing a baseline run, no input shaper - but these also now crash.

In case it's my issue I will do a wire continuity test from sensor thru wiring to connector for duet board, maybe the repeated movement caused the issue. I have also tried tuning only a single axis.

In my config.g
M955 P0 C"spi.cs6+spi.cs5" I41 Q2000000
To troubleshoot I tried:
M955 P0 C"spi.cs6+spi.cs5" I41 Q1000000 <---still crashes

Railcore 2 zl 300
Input Shaping 3.4.0-b1
Duet web control 3.4.0
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0 (2022-03-15)
Duet WiFi Server Version: 1.26

Recently upgraded to 3.4 as well. I can report that I had no wifi connection issues prior to upgrading. Last couple of days I've had intermittent connection drops over wifi from browser to dwc.

Maybe unrelated, u guys decide:
Last night I decided to do input shaping tuning. It was going well, I did like 11 different runs flawlessly with results/graphs to show it was working.

So the 12th run no matter what I try, in the middle of doing acceleration tuning duet crashes and the dwc becomes unresponsive and reboots itself.
This was newest beta version of input shaper plugin. I'm at work, I'll edit this post with version numbers, configs, whatever additional info is requested.

@adam-v3d said in Vector 3D's printer calibration:

I have a v4 of the calculator that I have sent to one use to test to see if my calculations are working correctly as I don't have a duet printer running at the moment.

Hey Adam. Any updates on the v4 version of your calibration tool. Specifically how to follow your process on a duet machine. In one of my earlier post, I posted the results from your current tool on a railcore.
Still willing to help if u need extra tester's.

@oliof
Thanks for the response. I also saw a different procedure and model outlined in the docs for the M556 command linked in my post above.
My interest is to make sure duet users can benefit from vector3d's method. He outlines a few reasons the common 20mm calibration model is not ideal. (I realize what you and I linked above isnt the common 20mm cube).
What I'm after here with these post is for duet users to be able to follow along with his new method. Currently, it only works for marlin and klipper.

I was waiting for some1 to post that video link here. I saw our firmware supports the M556 command similar to marlin and klipper. I bought the model and instructions knowing the duet RepRap wasn't supported so far in his video.
Anyway I have the measurements, but unsure how to apply the correction factors.

@mfs12

Ok. Thanks for headsup. I'll keep track.
