Every time I hook up my Arduino Duo (with all the g2 prerequisites installed on it) to my computer and try to register it with Chilipepr, the website gives me back this:

For your CNC device please choose the “tinyg” buffer in the pulldown before connecting.

Despite my Arduino Duo using TinyG2. Likewise, when I try to create the serial server through the command line, this happens:

2015/12/24 01:02:12 serial.go:606: Sending err back: We could not find the serial port /dev/ttyACM0 that you were trying to write to.

2015/12/24 01:02:13 hub.go:121: fro /dev/ttyACM0

2015/12/24 01:02:13 feedrateoverride.go:33: Inside spFeedRateOverride arg: fro /dev/ttyACM0 \n

2015/12/24 01:02:13 feedrateoverride.go:38: [fro /dev/ttyACM0]

2015/12/24 01:02:13 feedrateoverride.go:47: The port to write to is:/dev/ttyACM0—

2015/12/24 01:02:13 serial.go:606: Sending err back: We could not find the serial port /dev/ttyACM0 that you were trying to apply the feedrate override to.

For your CNC device please choose the “tinyg” buffer in the pulldown before connecting.

What is happening? Please help.

We need a bit more info.

What version of SPJS are you running and on what OS (Win,Mac,Linux) does it run?

The messages above would seem to imply Mac or Linux.
How do you start SPJS?
