Full-Wrap Rotary Engraving: Managing the Seam
A full wrap must close geometrically and physically after one circumference; scale error, object taper, slip and start-position error accumulate at the seam.
Rotary Y-Axis Soft Limits and ALARM:2
A Y-axis rotary can command more virtual Y travel than the flat-bed `$131` limit permits, causing ALARM:2 even though the rotary physically has no flat Y boundary.
Rotary Diameter, Circumference and Scale Errors
A wrong diameter/circumference/steps relationship stretches or compresses output around the object. Measure the relevant physical diameter and verify with a known-size test.
Rotary Setup: Chuck vs Roller and What Changes
Roller and chuck rotaries translate motor motion to surface travel differently. Correct setup depends on rotary mechanics, object diameter/circumference and controller axis configuration.
Rotary Mode: Set Up Cylindrical Engraving Without Losing Your Flat-Bed Workflow
Understand the parameters that map linear design motion to rotary movement and create a safe checklist for enabling and disabling Rotary Mode.
