That's why i have 3D printers now, printing parts for more 3D printers !
SEND HELP !!!!

my name is my1987toyota and I am a machine building addict.
See tommylight first step is admitting it. LOL

  So for the last few days I have been working on the main Hal. for my mill and a separate MPG Hal.
in the process of doing that I ended up writing a simple MPG hal. for a 5 axis with Feed and Spindle override.
 I will actually be using a 4 axis on the mill. If anyone is interested check out this subject here on the forum

Great work but it looks like you are consuming a lot of pins. This could pose a problem down the track if you are really a machine building addict who by definition wants to consume all the available pins!

Your next challenge is to use some of the MUX components to reduce the pin count. 

eg you can do scale select with 2 pins and  5 axis select with 3 pins
To do 5 axis plus 2 overrides you will need 4 pins which would allow 16 seperate selections
to do this you have to think in binary and from memory you need to convert from a float to long integer using the correct hal component..

 Admittedly yes it's a bit of a pin hog . Simple can mean many things this would be the easiest one I feel a nooby ( like myself ) could wrap their head around.
Also I am not fully up to speed yet on using mux4 or mux16 to bring the pin count down . I did fiddle around with mux16 a little to bring the pin count down but I didn't feel comfortable baking that into the code at this point . In my opinion their is  a lack of easy hal. examples and integration of MPG panels or pendants. Even pro athletes have to start with baby steps. Linuxcnc is no different. That said I do intend to do more complicated but lower pin count MPG's down the road.
