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

Application: This machine can work with a number of different Sainsmart machines to engrave on materials with a cylindrical shape. 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. And if you want to engrave cylindrical objects, the Sculpfun Rotary Attachment is a great buy! We have reviewed and tested it HERE. 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. 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

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. 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. 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. Y-Axis: this one is working without additional hardware. Since the normal y-axis motor is connected to the same port, you need to physically disconnect one of them during operation (or use a switch like presented in the next chapter). You can’t connect both at the same time.

Rotary as delivered by comgrow (plus a small manual and a small height adjusting piece to enable engraving wine-glass-shaped objects) 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. 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. Set the steps per millimeter (“steps/mm”) correctly (firmware). The LightBurn assistant is not required and is not activated. 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.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. There is a bar that says "type gcode here," select it, type the following depending on which step you followed previously: 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. If you have a Sculpfun S9, you can upgrade it to the improved x-axis mechanism from Sculpfun S10 with THIS UPGRADE KIT.
