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

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), Sliding adjustment of the shaft spacing: SCULPFUN roller adjusts the size of the space between the two shafts by sliding, and fixes the shaft by turning the knob by hand, which is simpler and faster than the traditional multi-stage fixing hole adjustment. 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. 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). Set the steps per millimeter (“steps/mm”) correctly (firmware). The LightBurn assistant is not required and is not activated.

Highlights

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. A: The resolution of the lines should be chosen according to the laser spot. Usually for modules up to 10W 0.08 mm or 318 DPI (Lines per Inch), for modules from 20W rather 0.1 mm or 254 DPI. But here you can still play, if lines are visible in the motif, you can reduce the line interval or increase the DPI.

The Rollers can be set at 5 different distances, each one 15mm further than the last. The adjustable range is 30-90mm. 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. 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).

Questions & Answers

Adjust the position of the rotary axis so that your cylinder will be parallel to the X-axis and perpendicular to the Y-Axis. Step 2B: Installation Guide for if your Machine has Two Y-axis stepper motors 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. Note: The front roller is a fixed roller and cannot be moved, only the rear roller can be adjusted. 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.

Adjustment of shaft spacing: The shaft spacing can be adjusted steplessly by sliding, and it can be fixed by hand-tightening screws.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 These values can be reduced accordingly. You have to feel your way towards the correct values; you could try a maximum speed of 1000 mm/min and an acceleration of 250 mm/s². If this is not enough, then reduce further.
