Hi PKM, It was awesome to see your Hexapod milling wood in the youtube. I hope you still posting news about your progress with this new machine. I will add your blog rss to my feedly.
Hi, I saw your delta's video on youtube, great job! Could you share your G-codes? Or could you tell us a cam software you have used? Or did you write the codes manually?
Really impressed with your builds! I'm interested in learning more about a hexapod config in machinekit/LinuxCNC, but ideally with rotary joints, instead of linear. Any recommendations for configuration resources?
Hi - I have a question regarding your ball joints. They seem like dumb questions after looking at them, but you might have learned something w/ your experience and I thought I'd ask. I'd really appreciate the help.
1. I assume your joints are metal to metal (ball and cup both metal). I see that an Omron-Adept robot has plastic inserts. Any issues w/ the metal? I doubt it based on use, but was wondering about stickiness. Here's the Adept bot: https://www.youtube.com/watch?v=8X7KsumRn24 2. Also, I'm assuming that the depth of the 'cup' for the joint is cut equal or less than 1/2 the diameter of the ball? Certainly, the 'cup' isn't greater than 1/2 the diameter of the ball or it'd be a press fit. Did you do 1/2" or a little less?
Any other suggestions to building a successful delta armed robot?
Your robots are excellent and I really like LinuxCNC.
Well the robot haven't worked much (and now it doesn't at all because of a weird issue with 7i48) so the metal joints are OK.
But for a delta 3D printer I use plastic sockets (different design though). I thought about plastic inserts too, but I did not want to complicate things back then. It was a temporary solution. Sure, go for plastic inserts! Right, I think the cup should be half diameter deep or just a tiny bit less. I think Adept joints design is very good.
So you're going to use LinuxCNC too? Now with joints_axis merged into master it should be easier. Good luck!
Great work!buen aporte!Can you email me the parts and plans also? I want to build this Delta robot

Hi, I don't have exact plans because the machine was changed a lot during the build. But I'll possibly share one of the models later.

Hi, great work!
ReplyDeleteWhere did you get those joints? It looks like they can provide a very large angle between the components.
Hi, thanks!
ReplyDeleteThe joints are custom made. Just a ball with a socket, actually.
Hi
DeleteAre you also selling these linear delta cnc router milling machine.

ReplyDeleteHello.
ReplyDeleteIt is a very nice work!!
I am also trying to build a delta robot like this and I'd be very happy if you can share the ball joints drawings with me.
Congratulations!

ReplyDeleteHello!
DeleteI write the code manually. Usually using loops and subroutines in LInuxCNC http://linuxcnc.org/docs/html/gcode/o-code.html
