That's looking good John.
Let us know when you are happy with it and have posted it permanently, need a link to point beginners to.

Certainly fills a hole. It's very difficult to know where to suggest someone starts, if they have no prior experience with other controllers or at least some general computer programming knowledge.

No point studying the many Fanuc type programming books and web pages, because as soon as you leave the first few G codes you are into numbered blocks and all sorts that Linuxcnc does not use.

BigJohnT OFFLINE Administrator Posts: 4947 Thank you received: 85 Karma: 134	It's a work in progress and any suggestions are welcome. The url is a permanent one well at least as permanent as I can maintain the hosting site lol. That is the reason I started the page as far as I know there are no LinuxCNC tutorials out on the web. BTW, it is done using AsciiDoc so the base pages are just txt files so anyone could write a section and send it to me to be added in. John

hey guys,

didn´t understand much. somehow it does not work.

maybe a better explanation could help you to help me.

i build an pyvcp radiobutton with 2 choices. i can choose I, for incremetal movements, or A for absolutely movements. also i have three spinboxes namend x y and z. so if on the radiobutton i is chosen and in my x spinbox i write the value 5, i want my x axis to move 5 mm in x direction.

is this possible to do that in any way?

greetz

BigJohnT OFFLINE Administrator Posts: 4947 Thank you received: 85 Karma: 134	Incremental is possible using halui and some logic components. Doesn't this duplicate the function on the manual tab? Absolutes might be a problem to figure out... linuxcnc.org/docs/html/man/man1/halui.1.html John

It can be done. But it will take a bit of fiddling.

MDI_COMMAND statements in the INI file create HAL pins and define a G-code line to run when the HAL pin goes high.
Because what you want to do takes more than one line of G-code, the MDI_COMMAND needs to call a subroutine.
See JT's example for how to do that part.

You then need the G-code that is called to read the PyVCP control values. The means that the values need to be connected to G-code analogue and digital inputs in HAL, and then the G-code inside the called subroutine needs to read them in to variables.
There is an example of how to do all this here: www.bodgesoc.org/lathe/lathe.html
