Hello Everybody,

I am new to this forum, but I am using EMC since several years.

The knowledge about it getting more and more....

Now I try to make my life easier, but can not solve the problem:

I was create a pyvcp panel with a spinbox, working correcly, also i can se the signal is changing, when I spin it.

The question is, it is possible to use the setted valule inside the g-code?

Forexample for repeat?

Like

repeat [#1]

Thanks your suggestions..

Regards:

Peter

Yes, I use a set of combo-boxes to set finish diameter, cut, feed and speed on my lathe. I generally use the same G-code to do all the lathe work in semi-auto mode.

You need to wire the spinboxes to motion.analog-in-00 and so on:
www.linuxcnc.org/docview/devel/html//man/man9/axis.9.html
(You can add extra analog input channels if you need to with a "num_aio" parameter in the loadrt motmod line
www.linuxcnc.org/docview/devel/html//man/man9/axis.9.html
You can then read the values in to the G-code using M66
www.linuxcnc.org/docview/html//gcode_mai...ec:M66-Input-Control
That passes the value into #5399 from where you can copy it into a variable of your choice.

Hello,

Thank you, for your help !!

This method is working properly !!!!!

The ports are checked during running time and the #5399 value are set to 0 when you load the ngc (predraw).

Thanks once more !!

Peter
