My rotary crystallization experiment needs a small stepping motor to rotate slowly (10 rpm) ten turns in one direction for a minute, and then ten turns back, forever. Do any Tic (or other) controllers support what I call “stand-alone” (or “stored program”) mode to allow this reversing cycle to be set up once via the GUI, stored in NVRAM, and executed on power up? Or do I need to add an Arduino and send serial commands from a program? I’m hoping to avoid this additional complexity. Thank you.
Hello.
We do not currently have a stepper motor controller that can be programmed to loop a sequence of movements like that. The Tic controller would need some kind of external input to tell it what to do (e.g. through USB, TTL serial, or I2C). You might consider providing the control signal from one of our Arduino-compatible A-Star programmable controllers, which are compatible with our Tic Arduino library that you can use to make the programming easier.

Thanks. I was using an A-Star for something else, and found that installing the TIC library and getting the motor to move under Arduino program control was easier than it looked. So all set.

I also share your question.
In addition, see below:

This is a true stand-alone device that may have a mode that meets your needs.
(CO2 provides a stepper driver … CO1 you supply the driver)
