Run the current Nexlock Brick System calibration workflow

Overview brings together the four-step workflow, current printer setup, goal cards, a searchable Test library and a preparation checklist. Choose a goal card or search the library by test name; filter the library to geometry or print-process comparisons.

Test bench contains Printer & starting recipe, the source-part selector and the four-step wizard. Find my fit starts from the connection problem; All tests keeps the complete searchable catalog available with categories and setup requirements. Expand the starting recipe to change the printer, material, nozzle, slicer, motion source or filament. Original source geometry audit and Test details, geometry & recipe notes keep the technical explanation available without interrupting the main steps.

Notebook keeps your private saved Sessions and Named setups. Open Results & photos on a saved session to record and compare individual attempts, measurements and photos. Use Save session to retain the current test before leaving it, then Resume from Notebook when ready to continue. Legacy profiles groups your account’s saved fit records for review, application and management. Save session keeps the test private in Notebook; the legacy profile buttons write to your account’s fit collection. Switching workspace tabs keeps the mounted test available; selecting a new test or changing its starting recipe resets prepared candidates, so save your progress explicitly before starting another comparison.

The Before you print checklist is a session preparation aid. It does not replace physical measurements, print confirmation or Tested evidence.

The installed filament preset is the compatible material baseline resolved by Companion. Selecting a catalog spool does not prove that an identically branded slicer preset was found. Review both names and retain the physical spool ID with the result.

Nexlock keeps the machine startup/shutdown instructions, hardware configuration and supported installed motion. The settings preview separates that baseline from the layers, structure, flow, temperatures and other process values applied by the selected recipe.

A missing printer/nozzle preset, unsupported build plate or older Companion requires setup attention. Manual slicer workflows continue to use geometry and a recipe for manual entry. A successful profile check establishes the available digital starting setup, not a completed slice or physical fit.

1. 1

   Review the printer, installed nozzle, material and selected slicer in Calibration. Choose the build plate you will actually use; Edit setup opens the existing printer and recipe controls.

2. 2

   For a native-project workflow, keep Companion running and choose Check installed profiles. This reads the installed machine, standard process and compatible material preset without generating a sample, saving a project or opening the slicer.

3. 3

   Review the matched preset names, build-plate temperatures and settings summary. Use matched setup explicitly applies the reported plate temperatures and records the preset baseline; the remaining Nexlock recipe values stay selected.

4. 4

   Choose a source and goal, prepare the candidates, then use the selected sample’s native calibration 3MF action. Open the completed file as a project in the selected slicer and inspect the slice.

A matched setup records fingerprints of the resolved machine, process and filament presets, plus the installed slicer version when it can be read. Saved sessions, named setups and result snapshots retain that information with their exact recipes. No local installation paths are included.

Check installed profiles again after updating the slicer or editing its presets. If the baseline changed, review the difference and choose Use updated setup for a new comparison. Native preparation checks the recorded baseline again instead of silently reusing different installed presets. Existing saved evidence keeps its original scope.

An unavailable slicer version stays unknown. Profile fingerprints describe the installed files; they do not capture printer firmware changes, automatic calibration performed by the printer, filament moisture or a successful physical print.

The current calibration page starts from a checked Nexlock Brick System source part. Ordinary source comparisons use its surfaces; interlock goals prepare declared versioned derivatives, including the rebuilt precision manufacturing mesh. Confirm printer, installed nozzle and material, then choose the source and goal. The active test list below uses the same definitions as the app.

The 4.80 mm mode is for supported plain rectangular bricks and plates. Other goals can compare the selected source’s whole-contour dimensional fit, shrinkage or printing process. Historical generated AU/MachineBlocks coupon offsets are a different workflow. A matching saved Tested profile can supply the baseline through Auto-select Tested fit; the numbered candidates still apply their controlled differences.

A receiving-fit comparison changes the printed underside. It cannot fix the opposite connection between printed studs and an unchanged reference receiver. Advanced contour adjustment changes studs, receiving walls and body outlines together; its wider effect is shown before selection.

All tests groups Connection fit, Surface & first layers, Advanced adjustments, Previous setups and Experimental tests. Search also recognizes the older technical test names. A restored file-based reference is a specific recorded setup, not a universal starting recipe for every printer.

1. 1

   In Choose part & goal, open Find my fit. Choose whether the parts feel too loose, too tight, will not sit flush, need a better finish, or need a starting comparison.

2. 2

   Choose Two printed parts or Printed + reference. For a reference connection, identify whether you are printing the Receiving underside or Studs on top. Optionally name the physical Reference part or set so you can use the same part throughout the comparison.

3. 3

   If the parts do not sit flat, distinguish a base that lifts or rocks from a connection that stops before seating. Choose I’m not sure yet when you need to inspect the cooled loose pieces first.

4. 4

   Review the suggested test, its reason, what changes and what stays fixed. Unavailable options explain the part, material, nozzle or setup requirement. Use this test explicitly selects the recommendation; the guide does not certify the result.

5. 5

   Review Distinct candidates and Printing in the selected plan. Two printed parts requires two matching copies of each candidate, compared in both directions. Downloads contain one model per distinct candidate; duplicate each in the slicer. A shared geometry plate is available only when the prepared layout fits.

1. 1

   Choose part & goal: search the source, use Find my fit or All tests, review the selected test and its candidate values, then Prepare candidates.

2. 2

   Print samples: select a numbered candidate and transfer its matching settings. Geometry candidates can share a plate when the checked layout fits; process candidates use separate recipes. Keep filenames, bed order and the supplied manifest with the kit.

3. 3

   Compare & repeat: compare the cooled samples against the same reference and select the actual sample number you prefer. Fit feedback helps identify a direction for another comparison; it does not mark a sample Tested. Refine an eligible closest sample when needed, or repeat the exact winner three times before verification.

4. 4

   Verify & save: enter the reference, spool, overall measurements, cycles and checks. Use Save session to keep this test in your private Notebook. After the complete result passes, Save legacy Tested profile & use part writes a reusable Tested profile to your account’s Legacy profiles collection. Save legacy custom profile writes an unverified setup to that same account-owned collection.

Guided fit comparisons choose a balanced, tighter or looser direction for the selected fit variable. A tighter-only set is not a suitable response to a connection that already requires too much force. Review the actual candidate values before printing. Expand Comparison range for Starting comparison, Fine refinement or Wider comparison on supported tests.

Current baseline labels the starting value inside this prepared comparison. It is not a claim that the source was left unmodified or that the physical fit has passed. A fresh guided comparison can begin at zero receiving relief; the historical −0.020 mm value is not a universal default.

In All tests, Tune connection grip retains Historical single-stud range · tighter trials under Comparison range. Every option is at or tighter than the −0.020 mm reference; it is not a general looser-fit search. The live table in the single-stud guide records those values.

A sample number is local to its own part, test, range and recipe; sample 4 from one kit is not a universal preset. Use the manifest and on-screen list instead of reusing a number from an older kit.

Feel ratings are selection aids, not measurements or Tested evidence. Changing a selected sample’s native recipe also requires fresh physical observations. Save session explicitly retains guide answers, supported fit-search context and sample feedback; old saved sessions remain resumable with their original recipes.

Refinement keeps the captured plate, filament and native preset information with its process. It changes the fit variable for the new samples rather than silently rerunning default process settings. Keep the source, printer setup and physical reference consistent.

1. 1

   For Tune connection grip and Advanced contour adjustment, mark the actual samples printed and cooled, then open Compare results. Rate each tested sample Too loose, Closest or Too tight against the same connection. Closest selects the candidate to refine or repeat.

2. 2

   Use Save session before leaving the comparison if you want to retain its ratings and progress in Notebook. Refine the closest sample starts a fine comparison around that candidate’s exact fit value and captured process.

3. 3

   If none are suitable, choose None fit · try tighter or None fit · try looser. The next comparison extends from the appropriate end of the current range and retains that end sample’s process. At a supported limit, review the part, reference and printing process instead of forcing further adjustment.

4. 4

   Prepare and print the new candidates. A new comparison clears the old printed checks, ratings, repeat confirmation and measurements from the working test; it does not transfer physical evidence to new geometry. Repeat the final winner before verification.

Use Explore connection systems on Overview, the Test library, or choose Compare connection systems in Choose part & goal for 3 complete-system candidates on one pilot part. All share the comparison’s fixed stud/contact settings and the same selected recipe, but several geometry features change together. The precision candidate has its own smaller body targets.

For contact refinement, choose the contact-fit goal and its connection system directly on the Calibration page. It compares 4 fixed local-contact levels inside that one architecture. These goals use fixed comparisons rather than standard/fine/wide sweeps. Interlock lab offers the same Compare connection systems and Tune selected system contact actions. Existing corrected-reference and fixed-stud comparisons retain their original behavior.

On Choose part & goal, expand Original source geometry audit to review the source summary before preparing candidates; expand View source stud measurements for the individual measurements. In Print samples, open Connection geometry audit to compare the prepared samples. Supported plain rectangular sources show every expected stud at a horizontal cut 0.8 mm above the body roof, with minimum and maximum directional widths. Compare those widths with the maximum X/Y span in the sample summary; a faceted stud can have different widths in different directions.

Complete means the expected studs were measured at that cut. Incomplete results or unavailable reports for unsupported geometry are not fit failures or successes. This read-only audit does not change geometry, settings or Tested evidence and does not measure a printed part, the whole stud height or physical clutch.

• Download the test ZIP for numbered STL/3MF files, recipes and material/process files.
• Use Companion for printers labeled Native project. For geometry handoff or manual import, open the candidate geometry and enter its matching recipe in the slicer.
• For a shared geometry plate, retain bed order and per-object fit metadata.
• Record the printer and spool used. Use Save session to retain the test and partial results in Notebook; selecting a different test or changing settings starts a new comparison.
