What changed in Zenomiq, newest first.

1.5 — 2026-07-28

Added

  • Running parameters preview. Gear 1 speed, both torques and Gear 1 load cycles are shown in the input card and update as you type the power, the wheel speed, the ratio or the wheel load cycles. Available in AI and Manual mode.
  • One Settings page instead of two. Every settings entry in the sidebar, including the new Geometry entry, opens the same page, which is split into a General tab and an AI Optimization tab.
  • A choice of column separator for exported CSV files, on the General tab of Settings. Comma or semicolon, remembered per account.
  • Help bubbles on the K-factor method row and on the three shaft inputs (shaft diameter, bearing span and pinion offset), explaining what each input means and where its default comes from.
  • A warning after an ISO 6336 calculation when the mesh is running at very light load or close to mesh resonance. It reports the dynamic factor and the specific load that triggered it, and lists ways to move the design out of that regime. It is advisory only and does not stop the calculation.

Changed

  • Lightly loaded gears: the dynamic factor changed, and with it the root and flank safety factors. In an ISO 6336 rating, the specific load that divides the dynamic-factor terms is now held at a lower limit of 25 N/mm. Below that load the old formula had no lower bound, so the dynamic factor grew without limit as the load fell and reached values far outside anything physical. The new lower limit brings the dynamic factor down, which raises the safety factors.

    A design carrying 25 N/mm or more of specific load is completely unaffected — its numbers are unchanged. Specific load here means the tangential force multiplied by the application factor and divided by the face width. If you are not sure where your design sits, re-run it — only lightly loaded gears moved.

  • CSV files exported from a saved calculation now use a semicolon between columns, matching the other two export routes. This one route used a comma before. You can change it in Settings.

  • The CSV export and the on-screen results summary now hide the same rows the PDF report already hid. With tooth-tip topping switched off, the two topping tool-radius rows no longer appear; with it switched on, the tip-shortening rows no longer appear. Those rows only ever showed zero. No calculated value changes.

  • Grey helper text throughout the app is darker and easier to read, and the descriptions under the settings fields are larger.

  • The Running Parameters card now sits directly below Design Settings in AI and Manual mode.

  • The permanent yellow note on the K-factor method C row is gone. The same explanation is now in that row's help bubble, where it does not take up space on every screen.

Fixed

  • The left-hand / right-hand choice now really flips the helix. Choosing left-hand used to produce a 3D preview and a STEP export identical to right-hand. The rating results are unaffected, because the strength calculation only uses the helix angle through its cosine.
  • A saved calculation now reloads the material and lubricant, the ISO 53 basic rack profile, the K-factor method and the Basic/Pro tier exactly as they were saved. All four were silently dropped, so loading an older case and recalculating it could give different safety factors from the ones on the saved record.
  • Saving a calculation no longer throws away the working state. Exporting the CSV or the STEP file after a save works again. When the state really is gone, the export now says so and stops, instead of quietly falling back to generic defaults and writing a file that looks plausible but does not describe the calculation on screen.
  • In Manual mode with K-factor method C selected, the five manual K-factor input rows no longer appear on the ISO 6336 card. Method C computes those factors, so anything typed into them was ignored.
  • Switching into AI mode no longer overwrites values you have typed with the defaults.
  • The ISO 6336 card no longer jumps on load. Rows that are meant to be hidden now start hidden instead of appearing for about two seconds first.
  • Warnings that a value was rounded or limited now appear straight after the calculation. They used to sit unseen until the next time the page was fully reloaded.
  • The material table in the ISO 6336 help bubble is no longer cut off. All four columns fit.
  • The 3D result and gear-selection panels now appear and disappear correctly in several cases where they did not: a leftover single-gear result no longer hides the pair view, and the selection frame no longer shows when there is no pair result to select from.
