Welcome to the SeeMeCNC Community

Has anyone compared the quality of their printouts from using the Berrybot3D Magnetic U-Joint (http://forum.seemecnc.com/viewtopic.php?f=54&t=1704) and the TrickLaser Carbon Fiber Tube Arms with Metal Ball Rod Ends (http://tricklaser.com/Carbon-Fiber-Tube ... M-CFTX.htm)?

Clearly these are both awesome ideas, but I want the best print quality so I'm wondering which one should I pursue?

I own both and really it's more of a how comfortable are you with fabbing?

If you are comfortable with fabrication then I think the magnetic arms are the best choice, if not the trick laser arms are not really far off from the magnetic in print quality. You'd be very hard pressed to see a difference infact.

However I do believe the magnetic arms will wear better after extended use.
