hi
I have a spinbox pyvcp and I would like to save and load the value every time I turn off and turn on LinuxCNC. I saw that I could do with paramsaver but I can not figure out how to use it.
some more information?
regards
Alessandro

There is a sample configuration here: www.mgware.co.uk/LinuxCNC/param-saver.html
But I imagine that is where you got it from?

hi
another question:
i need to write a variable eg. #35 into pyvcp spinbox halpin vistoll
i tried with file ini mdi_command so when i push a button execute :
MDI_COMMAND = #<_hal[pyvcp.vistoll]> = #35
but it's wrong seem i read halpin but i does not write.
when i read with another button it's ok
MDI_COMMAND = #35=#<_hal[pyvcp.vistoll]>
Is there a solution ?
regards
Alessandro

G-code access to HAL is read-only.
If you need to pass a value from G-code to HAL use the motion.analog-out pins and M68.
