Custom 6 axis robot arm project with AR4 software
I met Annin Robotics after I started my own custom 6 axis robot arm project. So, I had almost finished my project. I wish I had met Annin Robotics before I started my own project. But, despite everything, I found a way to take advantage of annin robotics. BTW, lots of thanks to Chris Annin for creating AR series robot arm and made them available to everyone. Thanks to him I discoverd many things and found solutions ways to my issues. Maybe I couldn't have AR4 robot arm kits, but now I am trying to adapt the software to my own project. I got Teensy 4.1 and connect the robot through Teensy. I hadn't have a stepper motor with encoder. But now I have. I have replaced stepper with encoder one. And now trying to work the robot with it. If I can enable stepper with encoder, I will be very happy. 🙂 Because it is different than AR4 structure, it pushes me. Secondly, in addition that, I am trying to connect the robot to RoboDK software. I have got AR4 beta driver from RoboDK and trying to use it. But couldn't be connected to the robot :/ Maybe someone of you can help me. This is my custom 6 axis robot arm. Now, it doesn't have any limit swtiches but I am working on: I am reading AR4 manual. 🙂 https://www.youtube.com/watch?v=o_KYxN9nW_M

I couldn't find J6 Housing STL file
I am trying tı build AR4 in 3D printed files. I couldn't find J6 Housing STL file among the files downloaded. Should I use aluminium /images/forum/media/b7b3c1dc9aeb3ddc.avif version for J6 Housing or is there any STL file I ca not find?

more torque needed
For my project, torque of Joint 5 motor is not enough. This one: /images/forum/media/cfefd83393982617.avif I need to increase torque . I think the best choice is using gear box. But the ball screw is inside of the motor. Can I stil adapt an planetary gearbox to the motor? Or any one have a suggestion to increase J5 tourque?
