OmTech 60W / 80W CO2 Rotary Steps-Per-Rotation & Calibration Tool
Eliminate oblong circles and vertical stretching on the OmTech 60W / 80W CO2. Use our interactive calculator below to correct your LightBurn steps-per-rotation or GRBL $101 commands, then download a millimeter-accurate calibration ruler SVG.
Rotary Steps-Per-Rotation (SPR) & GRBL $101 Calibrator
Preset: OmTech 60W / 80W CO2 (60W / 80W CO2)
Measure along the Y-axis (rotary circumference direction).
Enter this in LightBurn > Tools > Rotary Setup > Steps per rotation.
Safe continuous rotary perimeter without slipping: 224.7mm.
$101=100.000Always send this command in LightBurn Console after disconnecting the rotary attachment to restore flat Y-axis belt scaling.

Step-by-Step Rotary Setup & Test Burn Checklist for OmTech 60W / 80W CO2
- Power off machine; unplug Y-axis driver aviation socket and plug in rotary cable.
- Power on machine, immediately press Esc on Ruida panel to cancel homing sequence.
- Open LightBurn > Rotary Setup > choose Chuck > enter 10000 pulses/rev (or 3.5 ratio).
- Input precise caliper measurement of tumbler diameter.
- Test fire line on masking tape to verify exact diameter scale.
Worked Calibration Example for OmTech 60W / 80W CO2
Suppose you place a standard 20oz Skinny Straight Tumbler (Diameter: 73mm, Circumference: 229.34mm) onto the OmTech 60W / 80W CO2.
You enter a commanded test square Y-height of 20mm into LightBurn with the baseline of 10000 steps/rev.
If using GRBL steps/mm, the corrected formula produces:

OmTech 60W / 80W CO2 Rotary Calibration FAQs
Q1: How do I configure the rotary attachment on the OmTech 60W / 80W CO2 in LightBurn?
To set up the OmTech 60W / 80W CO2 in LightBurn: 1) Go to Tools > Rotary Setup. 2) Select your rotary type (Chuck). 3) Enter the factory baseline: 10000 steps/rotation (or check Y-axis $101 steps/mm). 4) Enter your roller diameter (25mm) or tumbler caliper diameter. 5) Enable the 'Rotary Enabled' toggle and test frame your object.
Q2: What is the factory default rotary steps/mm or pulses/rev for the OmTech 60W / 80W CO2?
The OmTech 60W / 80W CO2 uses a baseline of 10000 steps per revolution for chuck rotary mode, and 100 steps/mm for flatbed Y-axis movement. Drive roller diameter on factory rollers is 25mm.
Q3: How do I reset the OmTech 60W / 80W CO2 back to flat-bed laser cutting after rotary engraving?
When disconnecting the rotary attachment, disable 'Rotary Enabled' in LightBurn. For GRBL-based controllers, send the command: $101=100.000 in the Console window to restore true 1:1 flatbed Y-axis gantry movement.
Q4: What is the best way to focus the OmTech 60W / 80W CO2 on a cylindrical tumbler?
Lower motorized Z-bed; set focal distance using stepped aluminum puck (63.5mm FL). The focal length is 63.5mm with an optical spot size of 0.18mm. Always focus at the apex (highest vertical point) of the cup to ensure maximum beam energy density.
