Arduino based USB Pendant for Linuxcnc

Hrmm. But me manually sending values @ 115200 works. So that means the the arduino side (the sketch and the libraries) is working correctly?

I changed both ends to 9600 and same deal.

What does tail -f /var/log/messages show when you plug in the pendant?

What does the pendant LCD display when you plug it in?

Just 'X:*'

Just 'X:*'

It should display
If that is all you get, there is something wrong the arduino end

No sorry, that is after the first cycle

Should be

The sketch is unaltered. I've installed the IDE (separate install from my main copy) on my local machine then this morning I created a VM with only the libraries in the ZIP.

Well All three axis. But when it connects it places a "*" after the ":".

What is the prefix that HAL is sending to the AVR? via screen /dev/ttyUSB0 I can do "Y-0.1234" it populates the X: axis field with value specified.

Yeah exactly.

From serialcon2.comp

So if you send "X1000.999Y2000.888Z3000.777"

That should populate those axes with those values

Hi @all
can someone tell me what USB Device i put in the serialcon?

After reboot my PC this changes ever +1 usb 7-1: i.e. usb 5-1 / usb 6-1 etc...

I'm using LinuxCNC 2.7.7 on Wheezy.
I want to use only the DRO output no Key Functions or anything.
I changed the Arduino sketch without Keypad. Baudrate i d'ont changed.

Is this Installation from serialcon correct? (i'm not a Linux spec )

[strike]fh@v3:~/linuxcnc/configs/CNCV3$ sudo comp install serialcon2.comp[/strike]
[strike]sudo: comp: command not found[/strike]

Or must there a lot more?
I put this in my costum_postgui.hal

loadusr -W serialcon
....
net Xposition halui.axis.0.pos-relative serialcon.xposition
net Yposition halui.axis.1.pos-relative serialcon.yposition
net Zposition halui.axis.2.pos-relative serialcon.zposition

No more Files where attached...

Greetings Fritz

I seem to recall that USB devices also show up somewhere else on /dev by serial number.
That might be less mutable.
