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

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

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. Another important thing: turn off homing! Homing does not work with a rotary, since the y-axis doesn’t support homing anymore if the rotary is connected (only applies if you use the y-axis for the rotary, but that is the case for 99% of the users in my experience). You don’t need to turn it off in the firmware, but just don’t use it and don’t enable automatic homing at startup. Select “current position” as “start from”option. Never use absolute coordinates. 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. Compatible software: Lightburn, LaserGRBL, Benbox, GrblController, LiteFire, etc. There is no need to set up software because the surface linear velocity of the roller is the same as the original Y-axis velocity.

If you have a Sculpfun S9, you can upgrade it to the improved x-axis mechanism from Sculpfun S10 with THIS UPGRADE KIT. and press the connect button to the right of the baud rate value. If successful, the console should show "grbl 1.1f" or grbl 1.1h" 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. 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.

Final note: this is not meant to push anyone into donating. As I said, the wiki will be free to use and stay free as long as I can afford this passion. 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. 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. With LaserGRBL you can import vector files (NC, BMP, JPG, PNG, DXF…) and bitmap image files (bmp, jpg, png and gif), 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.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. Rotary setup in LightBurn. Showing values for the Sculpfun rotary (A), these should be adjusted to your rotary. Settings B are, as stated, not used for rollers. 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. 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).

Sliding space adjustment: SCULPFUN roller adjusts the size of the space between the two rubber rollers by sliding, and fixes the rolloer by handscrew, which is simpler and faster than the traditional multi-stage fixing hole adjustment. 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. The steps/mm are set appropriately for the rotary in the firmware: in this case, the value corresponds to the diameter multiplied by pi (i.e., the exact circumference of a roller). Since the steps per mm are correct, a direct relationship is given. So: “mm per rotation = roller diameter * Pi”. This is a perfect upgrade for expanding your engraving capabilities and adding variety to your projects. Designed to engrave tumblers and cylindrical objects with ease, this rotary roller is a must-have for any laser engraving and 3D printing enthusiast.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. Rotary as delivered by comgrow (plus a small manual and a small height adjusting piece to enable engraving wine-glass-shaped objects) 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. The Rollers can be set at 5 different distances, each one 15mm further than the last. The adjustable range is 30-90mm. 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.
