Hi Angel,
the robot is finaly working, all the things mounted and cabled and so on, electronics is ok and everything is fine. Now I’m making a simple interface in processing to control every joint of the robot separately; this is my first attempt but after I would like to implement a 3D model on the PC with the inverse kinematic in order to have a direct control of the robot in real time.
So I have two question:
– 1 with the grbl firmware you’ve uploaded on github and that I’m using is it possible to operate in jog mode? it would be great in order to have a joystick control style.- 2 do you have any piece of software already written and with open source license that you could provide to control the robot?
I’ve made my very first try using a Gcode sender (universal G code sender) and now I’m moving to the solution made in processing but maybe there is something already made that works fine and is open source.
Thank you very much,
Andrea A.Hi, ;
I’ve finally got it working, I’ve put some bigger balls into the bearing and know all the play that had before is disappeared and the mechanism is working, I only notice I have some backslash due to the gears but I will work on that later, for now it’s ok.
Thank you,
Andrea AgliettiHi Danny,
have you got also the original CAD files of the ART3 splitted parts?, I would like to add a fan to your design, or do you have a piece already modified with the fan addons?
Thank you so much,
Best Regards.
Andrea AgliettiHi Angel,
ok i will try to increase the torus radius, now I have too much play I’ve tryed to print your original design with both a professional 3d printer and my tevo tarantula but the result is near the same I have too much play and another problem I have is that the motor isn’t fixed strong enough and it is able to move a little when it try to rotate resulting in skipping of the shaft.
I’m also trying the ball bearing design of Martin. I’ll make some test when I’ll have some free time and I’ll give you some feedback.A question: do you have a skype account?, It would be great to have a talk so I can also show you my issue in a videocall.
Thank you very much.
Regards.
Andrea AgliettiHi Martin,
can you share the design file?, I’m having some issue with the original ball bearing and I would like to know how you’ve modified that, I don’t understand from you photos if you have placed a modified piece on the existing one or if you have replaced completely the original one with your version.
Thank you so much.
Andrea Aglietti
