I shot an iPhone video of the first test with all three axes assembled. Again, this CNC build is purposely the simplest and lowest cost build I could do. I'm still using two 3D printed timing belts and all printed parts. and the z-axis is held together with clamps. But as you can see it can now "cut" the "LinuxCNC" splash screen.
It will eventually have home and limit switches, Mesa card, and glass linear encoders but I want to characterize and document a low-budget build first. This is working out about as I wanted. The budget is still holding about $350. It seems to perform well enough to be useful. My computer has 37,000 ns of jitter so I've limited step rate to 8 kHz on all axes. Even so, I get a very reliable 30 mm/second movement on both X and Y. I should be able to be better because I have the drivers set to limit current to 2.0 amps with 4.2 amp motors. I think I can improve the 35,000 number. I'm working on setting up a gamepad ( target.com/p/logitech-f310-gamepad <https://www.target.com/p/logitech-f310-gamepad/-/A-13670128> ) as a pendant. It is looking like I will be able to do jogs, toutch-offs, and some manual milling operations with this $20 "pendant". https://youtu.be/wupYP2NNsXI -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
