SCULPFUN Laser Rotary Roller, Y-axis Rotary Roller for Laser Engraver Cutter Engraving Cylindrical Objects and Cans with 360°Rotating and 4 Height raisers, Support Diameter 6-150mm

Product Information

If you don’t want to change the steps per mm every time, you can use the LightBurn wizard. LightBurn then takes over the conversion of the lengths from the motif into the movements of the rotation roller. For this, LightBurn needs two parameters: “mm per rotation” and “Roller Diameter” (A in the following picture). These two values are explained quite simply, but the function is sometimes a bit complicated. Application: This machine can work with a number of different Sainsmart machines to engrave on materials with a cylindrical shape. To clarify the whole thing a little better, here is an example. With the Comgrow Rotary, I can choose between the following settings. The initial situation is as follows: My laser normally has 80 steps per mm in the y-axis; with the roller it is 65 steps per mm and 16 mm diameter of the rollers. Place the rotary axis in an appropriate position on the table, and connect the machine Y-axis motor cable to the rotary axis stepper motor.

There is a bar that says "type gcode here," select it, type the following depending on which step you followed previously: A great upgrade for a cutting surface is a HONEYCOMB BOARD. It makes a big difference and the bottom side remains clean when laser cutting. You can also expand the work surface of this machine with the Sculfpun Expansion kit, which expands the working area more than two times. We have tested the expansion kit HERE.

How to use: Disconnect the Y-axis motor wiring of the laser engraving machine, connect the SCULPFUN Rotary Roller to the Y-axis cable, and you can start using it. There is no need to set parameters in software because the surface linear speed of the roller is the same as the original Y-axis speed. Lightburn supports more formats: AI, SVG, DXF, PDF, HPGL, PLT, and RD for vector formats and PNG, JPEG, BMP, TIFF, TGA, and GIF for image formats. Move the tensioning wheel assembly to make the synchronizing wheel under tension, and tighten the fixing bolts. The Rollers can be set at 5 different distances, each one 15mm further than the last. The adjustable range is 30-90mm.

For the mathematicians among you, the value in the first case can also be derived mathematically: 40.8 = 65/80 × 50.26. That is, the ratio of steps per millimeter multiplied by the true circumference of the roll. Sculpfun Rotary Note: The front roller is a fixed roller and cannot be moved, only the rear roller can be adjusted. You can get millions of free vector designs on the internet, or you can use free vector drawing programs like Inkscape or QCAD (for more technical drawings)original scale high-precision engraving: SCULPFUN roller adopts high friction 70A rubber shaft to prevent slipping, and the linear speed of the rotating surface has been precisely calculated. Directly plug in the engraving machine cable to engrave the original image in 100% original scale. Does not enlarge or reduce the image. mm per rotation”: this is the slightly more complicated value. This value indicates how many millimeters LightBurn should send to generate a complete rotation of the roller. And here you have to distinguish two cases: Adjust the position of the rotary axis so that your cylinder will be parallel to the Y-axis and perpendicular to the X-Axis. Step 3: Install, Connect to and Configure LaserGRBL With LaserGRBL you can import vector files (NC, BMP, JPG, PNG, DXF…) and bitmap image files (bmp, jpg, png and gif), It's great for cylinder carving and etching. It has a stable design for multiple diameters. Spacing between the two rotary axes ranges from 17mm/6.6" to 33mm 1.2".You can engrave almost the same travel size as the machine. Equipped with a roller stand to engrave objects such as goblets.

I change the steps in the firmware to 65. Then I don’t have to use the wizard. If I still want to use it, I have to enter 50.26mm per revolution there (16 * Pi). Engraving Table Height】 This aluminum rotary laser engraver has a height of 2.36”. Please ensure the space between your machine’s laser head and engraving table can accommodate this added height. Adjustable axes distance up to 3.39” to process a wide range of cylinder diameters.Step 2A is meant for machines that only have a single port/stepper motor, such as the 3018 Pro, 3018 Prover, LE-1620 and LE-5040 Move the adjustable roller to adjust the distance between it and the fixed roller according to the actual situation. When the distance is appropriate, tighten the adjustable roller fixing bolts.
