So when I was setting up the G0602 lathe for CNC with dedicated X and Z
jog wheels I decided to work on an MPG for My Mach3 to Linuxcnc G0619 mill conversion as well. Little did I know the can of worms
that would turn into. I am sure it didn't help that I was also setting it up for Feed and Spindle override at the same time.
Right know I have the Hal. file with everything on it .

I found a few different hal. files to check out and that really helped me figure out how to make mine work. I guess Like with Arduino their are many ways to write a program to achieve the same goal. Still very frustrating to Noobs like me.
Thanks to rodw if he reads this, your hal. file on page 3 of your spaceship build is one of the ones that helped

another one that helped isn't on this site but if you are using the 5i25/6i25 and 7i76 cards this my help as well.
wapl.es/cnc/2020/02/23/linuxcnc-jog-wheel-setup.html
All in All I have so much to do as I continue to tumble down the Linuxcnc rabbit hole. I am starting to wonder which is more
enjoyable building the machines to make parts or actually making the parts? HMMM

Building the machines!
what if its making the parts to build more machines ?

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

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.rodw post=213064 userid=20660Great 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..
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.

I've actually been meaning to take my MPG code and move it into a dedicated hal file so it can be shared
Here is what I came up with excluding the loadrt and addf commands.. Still not sure the ilowpass has been done correct. First time I tried to use it I had a massive crash because 1 click was equal to one metre!

Hmm, I wonder where the preview has gone?
