I used Rhino 5 with a Universal Laser in a class I took at a local community college. I have now purchased an Epilog Fusion laser and am having trouble with vector cutting curves. The speed and movement on a straight line vector cut seems normal and smooth, but on curves the laser head is jerky and much slower. I am very new to both the software and the laser. I saw a post about the same problem from 2014, but the issue did not appear to have been resolved in that post. I have contacted Epilog about the issue and am waiting to hear back. Does anyone have any insight about what the problem might be? Thanks!
Just to clarify, when you ‘output’ to the Epilog laser, are you printing directly to it? Or, are you export some file from Rhino, perhaps DXF, and then importing this file into some other application which sends the geometry to the Epilog laser?
I am sending the print job directly to the epilog from Rhino using the print function. The Epilog shows up as a “printer” and I am able to set the speed, power, frequency and other settings in the print options window. Then the file shows up on Epilog’s panel (on the laser itself) as a job ready to print by hitting the go button.
Sounds like the Epilog print driver is converting splines to segmented polylines.
What happens if you convert your splines to arcs and then reprint. Alternatively, if the epilog has its own layout software, try saving a DXF out from Rhino with arcs instead of splines. It should be able to import a DXF.
Thanks, cdordni. I am new to CAD software and Rhino and have no graphic design background. I am not sure what the difference is between splines and arcs, but I will do a little research and try that and let you know how it goes. Being the first program I have worked with, I am really enjoying Rhino and it’s features, even though I have only scratched the surface of what it can do. During the 16 week course I took, I created many designs in Rhino (while using a Universal Laser at the school) and I’d really prefer to stick with Rhino if at all possible. Other than your advice, the only thing I have been told so far regarding this issue is to switch to another software. I want to avoid that if I can. Stay tuned…
You might also try the Rhino 6 Work-In-Progress (WIP) version to see if you get better results when printing. You can find a link to download the Rhino WIP in the Serengeti category here on Discourse.
Thanks, Dale! I’ll also try that.
