xTool D1 Pro Rotary Steps-Per-Rotation & Calibration Tool
Eliminate oblong circles and vertical stretching on the xTool D1 Pro. 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: xTool D1 Pro (10W / 20W Diode)
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. Add weight (rice or water bottle inside cup) to prevent roller traction loss.
$101=80.000Always 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 xTool D1 Pro
- Unplug Y-axis motor cable and plug directly into RA2 Pro motor connector.
- Send $101 command to match calculated rotary steps/mm if using GRBL mode.
- In LightBurn, enable Rotary under Tools > Rotary Setup, set Steps/Rev to 2560 (or $101 method).
- Set roller diameter to 16.0mm.
- When returning to flat work, send original $101=80.000 to restore Y-axis scaling.
Worked Calibration Example for xTool D1 Pro
Suppose you place a standard 20oz Skinny Straight Tumbler (Diameter: 73mm, Circumference: 229.34mm) onto the xTool D1 Pro.
You enter a commanded test square Y-height of 20mm into LightBurn with the baseline of 2560 steps/rev.
If using GRBL steps/mm, the corrected formula produces:

xTool D1 Pro Rotary Calibration FAQs
Q1: How do I configure the rotary attachment on the xTool D1 Pro in LightBurn?
To set up the xTool D1 Pro in LightBurn: 1) Go to Tools > Rotary Setup. 2) Select your rotary type (Roller). 3) Enter the factory baseline: 2560 steps/rotation (or check Y-axis $101 steps/mm). 4) Enter your roller diameter (16mm) 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 xTool D1 Pro?
The xTool D1 Pro uses a baseline of 2560 steps per revolution for chuck rotary mode, and 80 steps/mm for flatbed Y-axis movement. Drive roller diameter on factory rollers is 16mm.
Q3: How do I reset the xTool D1 Pro 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=80.000 in the Console window to restore true 1:1 flatbed Y-axis gantry movement.
Q4: What is the best way to focus the xTool D1 Pro on a cylindrical tumbler?
Lower the gold focus lever arm onto the highest point of the cup cylinder. The focal length is 50mm with an optical spot size of 0.08mm. Always focus at the apex (highest vertical point) of the cup to ensure maximum beam energy density.
