I just acquired a couple RV type mobile satellite TV antennas. They have traditional NMEA 17 type steppers in them, and I want to use them with something like the stepper motor drivers used on the 3D printers.
The stepper drivers are the ones found on the RAMPS 1.4 boards, usually A4988.
The objective behind this goal is realistically, servo motors are not going have the torque for an antenna more than a few inches in length.
I can provide a lot more details to those who ask the questions and are knowledgeable enough to implement something like this into the code. I build things - mechanical, electronic, but when it comes to programming, uh, I have to leave that to the professionals!
