Hello.
There are many things that can contribute to the maximum achievable speed of a stepper motor. You can find some general tips in Ben’s post in this thread (although please note that the values he mentions are not specific to your stepper motor). Also, you can reference the pull-out torque curve in the #1472 motor’s datasheet to get an idea of what the motor is capable of. You can find that datasheet under the “Resources” tab of the stepper motor’s product page.
If you try some of those things and still cannot increase the speed, can you post more specific details about your setup? For example, information about your power supply and a copy of your Tic settings file would be helpful. You can save a copy of your Tic settings file from the “File” drop-down menu of the Tic Control Center software.
