Right now the settings for device path as well as host and port are hard-coded at the top of the file using defines. These should really be run-time arguments to the executable.

right now the code sends a gcode comment when it switches axis or speed, but John has recently added a new broadcast command to SPJS which should be used instead. He documented the new command here: https://github.com/johnlauer/serial-port-json-server

it would be nice if the shuttle device could be plugged and unplugged with the program running similar to the way that SPJS can go up and down and it automatically reconnects.

I just bought a Shuttle, plugged it in to my Raspberry pi 2, and am trying to get it to work. I'm running ChiliPeppr on my desktop, talking through the serial port JSON server on the PI, which has an Arduino Uno running GRBL talking to my Sherline CNC mill (through a Xylotex 3-axis stepper board).

Here's a screenshot showing 2 ssh connections to the pi, along with ChiliPeppr running. I can jog the mill using ChiliPeppr.

(if that doesn't work, you can get it here: https://www.dropbox.com/s/53xlb5eau65ffzz/ShuttleCP-TimedOut.png?dl=0)

ShuttleCP is failing to connect to the serial port json server. The PI is on my local network using a wifi dongle. I followed the instructions in the README in terms of installing and configuring everything needed.

Any ideas?

right now, shuttleCP is meant to be compiled and run on a raspberry pi (ideally a raspberry pi 2). It would be nice if the code also compiled and ran on a mac.

The code is already scarred to drive indicator LEDs hooked to a Pi. Also add in the ability to read in buttons to send things like feed hold, resume, etc.

Thanks for the great script!

I'll be using it on my OxCNC running GRBL and bCNC on a RPi3 with 7" official LCD.

Two questions:
1- What is the purpose of the A axis? Just to stay in-line with the Tormach implementation and allow for future expansion? I was thinking of remapping the three middle buttons to X, Y and Z and use the previously-assigned X button to Home. Thoughts?

2- I have tried to run the script on startup via init.d but it doesn't work. Have you launched your script automatically, and if yes, how did you go about it?

Regards,

Mike

Hi,
I have SPJS running on a RasPi2. No issues with ChiliPeppr and SPJS on my Pi. I followed the directions to install shuttleCP and its' dependencies. ShuttleCP connects but it takes about 10 seconds to do so. After it connects, whenever I send a command, it fails, drops the connection and takes about 10 seconds to re-connect. And on it goes. Example output from the shuttle script is as follows:

--START OF OUTPUT--

I have tried three different versions of nopoll:
nopoll-0.2.7.b164
nopoll-0.2.9.b207
nopoll-0.3.1.b217
All three versions exhibit the same behavior.

Any ideas? Are there any log files anywhere that could give more info?

Nathan.

I like your module very much, but if i want to use the GPIO's with another program. How can i deactivate the wiringPi support?

Hi, @chamnit mentioned that you would like to connect your shuttleXpress jogging program with bCNC. I would be happy to help, or provide from the bCNC what is need.
Could you explain me the communication protocol.

Cheers
