    My Motion Simulator:
    3DOF
    Hey guys, I have a DIY motion simulator that I built, it works fine but recently I realised that one of the servo motors is getting hotter than the other 3 and that the values when I return the axis to origin is not the same. I have attached some photos to show what I mean.

    I understand my rig has a slight offset from zero at 074-079 but from the picture you can see that there is one servo that is extended way more than the other 3 at 192. This causes the motor to heat up quite a bit as it is under strain.

    This simulator runs on a PLC and the servo controllers are Delta ASDA-B2 servo motors I am using are delta motors model: ECMA-C1604RS.
    I am not the programmer of the PLC so have zero knowledge on how to go into there to change values, Does anyone know how I can manually offset that particular servo motor to a similar value to the other 3 from just the servo controller itself? I have looked through the manual provided by delta and I am genuinely quite confused as I do not specialise in servo or robotics for that matter.

    I have been trying to find answers online for quite a while but to no avail.
    It would mean the world to me if anyone can help. Thankssss!

    You would be much better off changing your zero at the shaft coupler than the servos.
