Hello tech experts,
I recently found stepper motors, controllers and PLC units extremely interesting by accident. Initially I am from a mechanical side of things and in the effort to expand and improve services I found that I have to combine electronics with mechanical.
The current challenge that I would LOVE to build but I am lacking the skill to do so...yet. The first project is Oscillation.
I have a stepper motor connected to a lead screw in a housing that clamps a welding torch. What I need now is a controller that will allow me to the following:
- Allow me to set the oscillation distance (time/distance motor steps in one direction)
- Dwell time (adjustable milliseconds before motor starts to step in the opposite direction)
- Speed of motor
Once this is done I would like to build a AVC unit. (Arc Voltage Control). Basically what it does it measures the real time voltage and when the welding torch gets closer or further from to the substrate the voltage drops or increases, then the unit should lift or lower the torch to maintain voltage to the desired voltage.
This is also done via a lead screw stepper motor. Challenge yet again is the electronic side of things. I need a controller that will measure the voltage and tell the motor in which direction to step for how long to maintain the required voltage. I also need to set the required voltage.
Any ideas for a heavy amateur which would love to start building the things?
