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. Place the engraving material between the two rollers and confirm whether they are far enough apart to support your cylinder without lifting it up too high. Generally, the lower the cylinder sits, the better. Adjust the position of the rotary axis so that your cylinder will be parallel to the X-axis and perpendicular to the Y-Axis.

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. 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. If you have a Sculpfun S9, you can upgrade it to the improved x-axis mechanism from Sculpfun S10 with THIS UPGRADE KIT. Test fire your laser at a low power, 5% or less, and make sure that your laser is focused to a tiny point.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

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. 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% proportion. Does not enlarge or reduce the image. 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) 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. Huge engraving space and 4 raising feet: SCULPFUN roller base design is lower and stable, and equipped with 4 sturdy metal raising feet, so that it has a larger engraving diameter of 6-150mm, which can meet more engravings. need. Metal feet are more solid than plastic feet, and the machine is more stable when engraving.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. Application: This machine can work with a number of different Sainsmart machines to engrave on materials with a cylindrical shape. 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.
