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
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.
