2.2.1   setting The Bowler Hand default setting controls whether new bowler profiles and new spec sheets are pre-filled as right-handed or left-handed. It is a time-saving convenience — nothing more. You can always change the handedness on any individual bowl...

2.2.2   default The Grip Type setting controls which grip style is pre-selected when you create a new spec sheet. Choosing the right default for your shop saves time — your drillers won't need to manually switch the grip type for every new client. 🤚 What Is ...

2.2.3   display The Measurement Display setting controls whether span, oval, bridge, and depth measurements appear throughout Spectre Cloud in decimal format (e.g. 4.25") or fractional format (e.g. 4 ¼"). This is a display-only preference — the underlying val...

2.2.4   display The Oval Degree Increments setting controls the step size of the degree selector in the Oval Calculator. You can choose between 1° increments for fine-grained precision, or 5° increments for faster, broader selections. The right choice depends...

2.2.5   default The Insert Installation default controls which installation method is pre-selected when creating a new spec sheet — either STD (standard glued) or VACU Grip (vacuum-style). Setting the correct default for your shop means your drillers spend le...

2.2.6   default When fitting a bowler with VACU Grip inserts, Spectre Cloud calculates the two hole sizes required for the two-tier drill based on the insert's outer diameter (O.D.). The lower hole matches the insert O.D. so the insert seats and glues at the ...

2.1.1   setting Spectre Cloud is available in nine display languages. Changing your display language updates all menus, labels, and interface text across the app — your bowler data and spec sheet content are not affected. 🌍 Available Languages Languag...

2.3.2   oval When drilling an oval hole, Spectre Cloud needs a reference point from which to calculate the initial pitch of that hole. Because an oval opening has width — unlike a round hole, which has a single center point — there are two valid ways to defin...

2.3.6   oval The Flip V/H on oval cuts setting controls the display order of the vertical and horizontal values in the oval cut cards shown by the Spectre Cloud oval calculator. This setting should match the order your drill press digital readout (DRO) displa...
