📅 2026-07-25 · Full changelog
✨ Features
- model-fit identification, joint optimisation, and tuning-page overlay fixes (
62c3f84) - scale-aware step-jump capture, live stage-status timeline, richer session report (
1aebed9) - automate preflight calibration, grade the result, and write config.g (
1f3bffe) - seed auto-tune from a Ku/Tu search, verify every accept, roll back safely (
e1bd3a4) - tune with the axis loaded, keeping moves inside its travel limits (
c74ca3f) - evaluation engine, About dialog, results download, UI cleanup (v2.1.0) (
f93877b) - configurable auto-tune cycles (default 3) to iterate P/D/I (
f1ba507) - auto-tune A/V feed-forward; declutter step 4; disconnect note; graph guide (
7c63da3) - persist UI selections across navigation (
3d75a71) - automatic PID auto-tune (P -> D -> I, hands-off) (
67edde9)
🐛 Bug Fixes
- real type errors in test helpers that only a full (test-file-inclusive) typecheck catches (
27a05ee) - unblock the v2.2.0 CI build, update dependencies, de-specify 1HCL references (
a35438c) - judge loaded-axis tuning on real move metrics instead of step-response ones (
39eea67) - stop noise-driven P backoff and premature V plateau in auto-tune (
ee5ab68) - iterate A/V every cycle and push the feed-forward harder (
cc6839b) - tune from a real G1 move, not the V64 manoeuvre (which didn't rotate) (
d86f1ad) - auto-tune re-asserts closed loop so it moves after a reboot (
ca12fd9) - mode command must not force direction (S1); revert auto-calibrate (
08bae9c) - auto-tune calibrates the encoder before tuning (root cause of no-move) (
569499c) - auto-tune now (re)asserts closed loop so the step manoeuvre actually moves (
6a402f1)
♻️ Refactoring
- use the standardised runtime AboutDialog (runtime v0.8.1) (
dceb7ca) - use shared HelpTip from dwc-plugin-runtime v0.7.0 (
55c69b1)
🧹 Chores & CI
- remove inherited Duet3D CLA Assistant workflow (
f202923)
📦 Other changes
- Rework UI into a step-by-step tuning flow + add tooltips everywhere (
7e733be) - Port to DWC 3.7 and rework closed-loop tuning UX (
f1b2354) - Add CLA workflow (
f43e3b7)
📦 Install
- Download
ClosedLoopTuning-2.2.0.zipfrom the Assets below. - In DuetWebControl, go to Settings → General → Plugins and click Install Plugin.
- Select the downloaded ZIP and accept the third-party-plugin prompt.
- Reload DWC, then open Plugins → Closed Loop Tuning.
🔧 Built against DuetWebControl 3.7.0-beta.2 (
6a6c726, refv3.7-dev). Use a DuetWebControl build at or near this version.
⚙️ Requires a Duet 3 board with closed-loop driver support (a Duet3D Expansion 1HCL / M23CL, or any other RRF board reporting closed-loop driver telemetry). Tuning moves a single driver — make sure the axis is in a safe position before recording.
