Confirm that the selected candidate and three matching copies were printed with the recorded recipe.
Identify the physical reference part and spool/batch. Use the same reference throughout the comparison.
Measure the complete width, length and height, including studs for Nexlock Brick System trials, plus the worst seating gap. The page shows the exact target bounds for your derivative.
For reference-stud, fixed-stud and experimental interlock trials, measure the straight gripping diameter below the tip. Perform at least 10 connect/release cycles on every copy.
Complete the process, flatness, surface, insertion, retention, release, alignment and applicable reverse-direction checks. Single-stud profiles, the corrected reference process and experimental interlock variants require their additional one-stud hold check.
When all targets pass, select Verify this source and recipe for use — mark Tested, give the setup a name, and save.
| Observation | Required result |
|---|---|
| Matching printed copies | At least 3 |
| Assembly/release cycles | At least 10 per copy |
| Overall width, length and height | Each within ±0.10 mm of the displayed target |
| Worst assembled seating gap | ≤0.10 mm on every copy |
| Straight stud grip | Within ±0.05 mm of the displayed straight-stud target when required |
| Single-stud refinement | Every copy holds for 10 seconds after cycling and releases without damage |
Before marking a normal-speed candidate Tested on a Companion-supported printer, prepare it through Companion. The website records the returned machine preset, standard process name and resolved motion values with that candidate. An unresolved native-speed recipe can be saved as Custom but cannot receive Tested status.
A changed installed motion preset is rejected when reopening a recorded recipe. Use Reset to current slicer speeds and make a new comparison to bind the new values. Existing saved records and their original evidence stay intact.
Tested is your recorded verification for the exact source mesh, printer, nozzle, material and recipe. Nexlock checks the completeness of those observations; it is not LEGO, manufacturer or independent laboratory certification.
The Results workspace in the private Notebook records individual attempts, optional measurements and photos. Those observations and the test bench’s Too loose, Closest or Too tight feedback do not replace this verification workflow or automatically create Tested evidence.
A profile with missing evidence can remain Custom or Unverified. Altering geometry, source, printer, material or the physical process invalidates the earlier result for the changed setup. Existing profiles keep their original verification scope; an older multi-stud check does not certify the newer single-stud requirement.
A new interlock variant does not inherit Tested status from its original source, the corrected reference, the separate fixed-stud derivative or another interlock revision. V1 and v2 records retain their own geometry and evidence. Precision v3 and any changed contact target require their own applicable physical evidence. The selected system, stud/contact settings and source identity belong to the stored process and fit record.
The interlock pilot requires the applicable stud measurements and single-stud hold check alongside the existing repeat, flatness, surface and seating checks. Measure the candidate’s own target bounds: v3 deliberately has a smaller exterior body than v1/v2. Opening a saved variant restores its recorded values; an experimental label alone does not establish a physical pass.
Use the saved calibration profile controls to restore a compatible setup. Profiles carry more than a clearance number: they can restore printer, material, nozzle, layer height, flow, temperatures and the complete recipe. Auto-select Tested fit reuses a fully matching verified setup on setup/source selections; its requirements are explained in Choose the printer and installed nozzle.
The profile manager is grouped by printer and can filter to the selected machine. Delete removes a profile record, while current numeric values and settings already saved in a part remain separate records. Read the confirmation before deleting.
