Okay…this is the very first time I have posted on these forums. I would like to thank all those in advance for being kind to a newbie asking for help and also for the help you can and will give me.
Here is my concept…
I am looking into making a machine prototype to see if it will work at all to help people automate production processes. This one in particular is going to be needing a frame structure that I plan on building from this stuff here:
So basically it will be sort of like a CNC machine but only using Y axis and three different Z axis.
With that said, I am going to need at least 6 stepper motors minimum maybe 7.
I am wanting to make an LCD screen with options to choose from for set up of the start and stop points of each motor for at least 4 of them. So my coding is going to need to be able to use the push buttons to store the set distances and repeat on the full cycle over and over again until a stop button is pressed. Once that stop button is pressed it all returns back to each of their start points.
I am going to use a rotary encoder for the ones attached to the sprocket design x2 so the user can set the positioning of that set up and then it stays the whole time in that set position.
All the others need to work in sync of one another in their due times…eg; MOTOR 1 moves DOWN…then stays in down position for it’s whole cycle…as MOTOR_1 is in the DOWN position MOTOR_2 moves to it’s set end point for the rest of the cycle…MOTOR_3 moves to it’s set end point…then MOTOR_4 moves to set point while MOTOR_2 moves back to original set point…then MOTOR_1 and MOTOR_3 move back to their set points…then it all starts back over again after MOTOR_4 moves to set point.
My question to the auto stuff is this…Can I use rotary encoders for the steppers that need to be set up or would I need to use something else for that purpose?
If I had an LCD screen with setup options for the motors and to cycle through the options I use regular push buttons, but when I go to the option of setting the start position and the end positions could I use the encoder and once I push down it will store that distance in the loop?
I hope this makes sense to you all?!? It is easier for me to see it and make it how I see it than explaining it. Would all this need multiple UNO boards talking to each other or would a specific board do for all? I guess I would need the H-bridge chips to hook my motors up separately or would one relay switch type board work for two or more? Would I need the Relays for higher voltage devices to be efficient with it all?
