I talked with RoboDK for the AR4 Driver and they sent me this file, I will try to use it and also said this driver is compatible with Travel Track, so here it is the driver and the guide to how to install it
Robot Drivers - RoboDK Documentation
Student licenses have all the features of Professional Licenses. No need to do any extra on the license or payment. The AR4 linear movement commands behind the scene look like this : MLX286.83Y0.13Z438.45Rz179.98Ry0.00Rx179.98Tr0Sp25Ac10Dc10Rm50WF.
The Tr0 is what command the rail position, so you can try to add a value to the Tr in the driver. Actually its 0 by default.
Doesn't work, robot wont connect.
I get a number of questions regarding connecting RoboDK to the AR4. During the initial development of the AR4, RoboDK contacted me and they requested I make the AR3/4 compatible with thier platform. I agreed, RoboDK was quite involved initially. They requested quite a bit of restructuring of the code and kinematics which I wasn't at all thrilled about, but in the interest of collaboration and getting RoboDK online I went along with it. Shortly after the release of the AR4 RoboDK went radio silent and stopped collaborating on any development. I don't know if they are going out of business, are short staffed or what challenges they face. They have responded to a few people sporadically including providing the driver attached to this thread. This will work with teensy sketch version 1.3. It should also work with version 2.2 but I haven't tested it. To connect to RoboDK, in the setting set the Robot IP to 127.0.0.1. Set the Robot port to your teensy com port. Make sure at the bottom you have selected the driver py file.

hi @Chris Annin can you upload that driver in the screenshot please? Im trying fix the sent me one but It doesnt work, I want to try with the one on the photo.

robot wont connect.
That's not true. RoboDK gets connected to the AR4 Teensy V3.00 with both Mateo's and Chris's drivers successfully. My physical robot is under major rebuild so I tested the connection just with bare Teensy board with nothing plugged into it. But I can read out the position of the board and move the joints as well so if I retreive the position again it gets updated.

Have you connected and controlled the AR4 on the DK robot? If so, please show me the connection part.
