Hello everybody, first off I would like to say thank you to anybody who is willing to help me.
I have a project I've been thinking about for the last 15 years. I have many of the mechanical problems solved. About a year ago I began to delve into the Control end of the project and quickly learned how much I didn't know about this field.
I'll do my best to provide the details I see asked for in other posts. So here it goes.
About a year ago I bought the book by Jon Stenerson titled "fundamentals of programmable logic controllers, sensors, and communications”. This third edition book help me feel like this was something I could pull off. However now that I am to the point of making connections I'm afraid of ruining expensive electronics.
Machine description:
My machine will be using a single motor to drive a cutterhead roughly 6 feet down a track. It will do so using an acme threaded rod. Upon reaching the end the cutterhead will return to the point of origin and again turn around and repeat the cycle. At the start I would like the motor to ramp up to speed in two seconds then continue to travel to the far end where it will ramp down over two seconds, stop, Reverse rotation, ramp up and continue back to the point of origin at speed until that sensor is triggered. Although I don't know at this point how many of these cycles will be required, my best guess to start would be 200. So I anticipate using a counter to stop the machine when the cycles are completed. In the future possibly some sort of cutter depth detection. At this point I have not purchased any emergency stop devices, but I understand safety is first even though this is a garage project.
I'm sure there are other details I have left out. I will provide them as best I can.
