Arduino based USB Pendant for Linuxcnc

The 'pins' you are linking do not exist, the MDI commands are already being activated by specific setp inside serialcon.

Thats what i have tried, but no Response in LinuxCNC, only my Text on the LCD changes.

For my Understanding:

The Key i press sends the Arduino ie. "1" to serialcon2
serialcon2 sends i.e. MDI-Command-01 with 1 to postgui.hal
postguihal. Looks what "01" is and fire up the Command that stands in the [Halui] Section...

Is that correct on the whole?

The Key i press sends the Arduino ie. "1" to serialcon2

Correct

serialcon2 sends i.e. MDI-Command-01 with 1 to postgui.hal

Wrong, postgui.hal is just a file that is processed after the GUI is built, because pyvcp pins will not have been created
until then.

serialcon executes the command which changes the state of a halui pin

postguihal. Looks what "01" is and fire up the Command that stands in the [Halui] Section...

halui looks up the MDI command which relates to the number and executes that.

Hello, I am new to Linuxcnc, and i need some help. I tried to make the arduino pendant but I have a problem. You can see in picture 1(Linuxcnc is not started)

and in picture 2( that's what appear on the lcd when I start linuxcnc). I think it's a connection problem. Any advice? Thank you

Without a lot more information I can only guess.

At the most basic level, make sure that the #define DEVICE= definition in serialcon2.comp is correct for your board, it needs to be whatever port you used to upload the arduino script arduinopendant.ino

Failing that, you need to attach all your config files (ini and hal), run with DEBUG=7 in your ini file and attach the debug output from stderr and linuxcnc.log

Hello Mr ArcEye. I tried a fresh install for arduino pendant, and I got: " Pin 'halui.axis.0-pos-relative' does not exist" .

In custom_postgui.hal I have to put only
"loadusr -W serialcon2
net Xposition halui.axis.0.pos-relative serialcon2.xposition
net Yposition halui.axis.1.pos-relative serialcon2.yposition
net Zposition halui.axis.2.pos-relative serialcon2.zposition" ? Thank you

Please don't send me personal emails, I am not going to answer them

halui.axis.0-pos-relative is a valid pin, but without your config files I am not going to guess whether you have even enabled HALUI
www.linuxcnc.org/docs/devel/html/gui/halui.html

Hello. I'm sorry for the personal email. Here are the config files

For starters, you are trying to load the component twice

Once right at the start of adna.hal, before any rt components have been loaded
and then again in custom_postgui.hal

It should only be loaded once in custom_postgui.hal, after everything else is loaded.

New to CNC (researching to build my first CNC router), but i am not entirely new to Arduino. i spotted this thread, and it instantly got my brain thinking about what i could build for a pendant. My first thought was to use an Xbee i have to make a wireless pendant.
Very neat project!

ArcEye, have you considered using a Nextion display for more advanced pendant display features?
I have a 4.3" Nextion display i was thinking of incorporating into a wireless (Xbee) pendant.

I haven't started building my CNC router yet, but my brain is still churning at the idea.
