Hi, I have a Maestro connected to a Tic, driving a stepper. I have set-up the Limit Switch Reverse and checked Enable Automatic Homing.
After I turned on the switch, I can see the “Limit switch active: Reverse” turning yellow.
I do not see any changes in the Maestro Control Panel. Is this normal? If the servo on Maestro is still at a position other than zero, how am I supposed to make it zero?
I have not connected yet the stepper motor and just wondering what is going to happen.
Thank You!
Hello.
I have moved your post to it’s own thread since is a different enough question and the other thread was 3 years old.
It is not entirely clear to me what you want to happen, but the automatic homing is a feature of the Tic; it does not communicate back to the Maestro about it by default. Can you post more details about what you are doing and how you want your setup to work?

Hi Brandon, please review this scenario:
- I am powering up the system
- the Maestro shows that the motor is not at zero.
- the stepper motor linked to Tic and Maestro is not at zero.
- I am doing an automatic homing based on Tic settings
Will the motor turn back until the limit sensor turns on?
The Maestro is still shows the motor is not at zero because Tic does not communicate back to Maestro. How can I can set the motor at zero in Maestro?
Hopefully I could explain it better this time.
It sounds like you want to use the Tic in RC position mode and control the stepper motor’s position from the Maestro. To make sure the Tic maps the correct input to the expected output, you will need to configure its RC scaling settings. You can do this from the “RC and analog scaling” box in the “Input and motor settings” tab of the Tic Control Center.
To configure it, I recommend connecting the Maestro to the Maestro Control Center and the Tic to the Tic Control Center at the same time. Then you can follow the instructions in the “Setting up RC position control” section of the Tic’s user’s guide for using the Setup Wizard to configure your input signals from the Maestro. However, since you are using a limit switch when the Setup Wizard asks you to set the input to the neutral position, you should instead set the slider in the Maestro Control Center to the zero position (i.e. the same position you will use when prompted for the minimum position). You will get a warning about the minimum and neutral position being the same (which is fine in this case). The homing procedure sets the homed position as the 0 position, which always maps to the Tic’s neutral position, so no values less than the neutral position will be reachable. You should also set the minimum target position as 0.
After this, whenever you run the Tic’s homing procedure, the Tic will move the motor to whatever position the Maestro is commanding after it finishes.
