Getting Back Into Parker 6K4 / 6K6 Controller Programming Again
Its been a long time since I did any work on the Parker Controllers, but I have been having the itch again for quite a while to do some more work on it. There were many things I was doing with the controller that could have been optimized, or improved – such as better feature detection and improved latency. I also never really got around to adding encoder support for any of my previous projects with the controller.
I recently got a Parker 6K6 controller from eBay to work with. They are available for less than 50 dollars nowadays. Its been a lot of fun writing new code to talk back and forth with the controller in a proper, organized way. I have made a new basic communication library that allows easy connection and Send/Receive capability and can be shared across various C++ projects, so if I want to make something new I can just import that code and get going. Adding an interface with wxWidgets 3.xx is fairly straight forward and saves a lot of time. A long time ago I had used an old Parker controller (It wasn’t a 6K4, it was a much older model that used an ISA connection card) to make an experimental CNC routing table for a saw. It was pretty basic, it just about worked but wasn’t very good.
My son is also going to tech school and has been expressing an interest in learning how to work with CNC machines a little more in-depth than just loading a model and pressing the Start button, so I think if I can teach him some of this from a purely technical level, it will help him understand better. I think that him helping to build the machine and understand the programming will be quite beneficial. G-Code in itself is quite a complex thing to learn, especially from an optimization stand point, so we will have to see how it goes.
As I make progress in code, I will make some updates here. If you are interested in this sort of thing or have any questions, let me know in the comments below. Not sure anyone even uses this controller anymore!
