<p>LightObject's mini rotary for small K/D40 laser units or other CO2 and fiber laser engraver machine. This is the roller rotational axis option great for engraving tumblers or small bottles. </p><p>The rotary employs two-axis with four silicone rings on the rolling bars to prevent object from slipping. The silicone rings are soft and do not scratch the objects you are trying to engrave.  It comes with a supportive arm to provide additional stability when engraving. </p><p>Note:</p><p>Additional stepper driver is suggested if your controller supports a rotary axis, but can work just fine as it can run entirely off your existing laser engraver stepper drivers.</p><p><strong>Specifications: </strong></p><ul><li>Rotary Type: Roller</li><li>Motor: 42HS03 1.8A (NEMA 17)</li><li>Roller Length: 200mm(8")</li><li>Roller diameter: 25mm(1")</li><li>Roller Adjustable distance: 20mm(25/32")</li><li>Dimension: L 300mm(11-3/4") x W150mm(5-7/8")</li><li>Suggested motor driver: Mini 2 phase 2A 1-axis stepping motor Driver</li></ul><p><strong>Disclaimer:</strong> The k40 stock mainboard will not be able to drive this rotary,  using an external motor driver is highly recommended. </p><p>Technical support by email, forum support, and phone is available.</p>
