Perfectly matched with engraving machine to engrave round objects】The One-piece rubber laser engraver rotary, hardness up to 70A, stronger friction, allowing you to perform 360-degree engravings on round or cylindrical objects such as cups, pens, bottles, pipes, bowls, drums and tubes and over-length plate engraving or cutting. Move the tensioning wheel assembly to make the synchronizing wheel under tension, and tighten the fixing bolts. 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. 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.

Step 2B is meant for machines that use two stepper motors for their Y-axis, such as the 3020 Pro Max, LC-60A, and 4030 PROVerXL.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 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: 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. 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 And if you want to engrave cylindrical objects, the Sculpfun Rotary Attachment is a great buy! We have reviewed and tested it HERE.

Free useful accessories: a free soft ruler to measure the size of object; 4 free raising feet, which can be used to increase the height of a variety of machines. 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. The options are described in the LightBurn documentation, but it is a bit hard to understand there for non-technical users, I guess. As mentioned, when you press Test, the roller rotates the small rollers once 360 degrees. So, the object (that might be lying on it) doesn’t even move all the way around (as long as it is larger than the diameter of the driven rollers).

Rotary as delivered by comgrow (plus a small manual and a small height adjusting piece to enable engraving wine-glass-shaped objects) If you have a Sculpfun S9, you can upgrade it to the improved x-axis mechanism from Sculpfun S10 with THIS UPGRADE KIT. Note: The front roller is a fixed roller and cannot be moved, only the rear roller can be adjusted. Either way, you should now have a functioning rotary connected to your laser system. The last step is to set it up for use in your laser tool. I’ll show the tool from LightBurn. Place the rotary axis in an appropriate position on the table, and connect the machine X-axis motor cable to the rotary axis stepper motor.With LaserGRBL you can import vector files (NC, BMP, JPG, PNG, DXF…) and bitmap image files (bmp, jpg, png and gif), 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. Z-Axis: the controller board offers another port for a z-axis motor. You could also use this one. Since the Sculpfun board does not contain the stepper driver module for this axis, you need to add one yourself (like this one). Then you have another axis and can control the two motors independently. If you don’t plan to integrate a z-axis, I would recommend using this option because you have less (no) settings to switch between the modes. Here is another video that explains some additional things for the workflow: https://www.youtube.com/watch?v=wL6tXOupQgo (LA Hobby Guy). But the “saving and loading settings”– stuff is not required if you follow my tip using macro buttons. Example Set the steps per millimeter (“steps/mm”) correctly (firmware). The LightBurn assistant is not required and is not activated.
