OK. I did a quick search and couldn’t really find what I’m looking for. I’m trying to get tinyg to work and so far am coming up with nothing . I’m trying all this on a 2016 MacBook Pro, 2.9ghz Intel i7 with 16 gb of memory. Chilipeppr is working as it should, even the 3d environment.

The problem is somewhere in the communication between the laptop and the tinyG board. I hooked up my son’s laptop that is running Win 10 and it worked fine.

So, with the Mac, running MacOS Sierra v. 10.12.5, I downloaded the JSON server for Mac OS X. When I fire up the JSON server, I see 6 different ports. I’ve tried connecting to all of them, one at a time, and the end result is the same. It appears that commands are sent but they are not going through.

Anyone know how to get this running?

Are you sure cu.lpss-serial2 is the correct serial port? One way to tell what the correct port is, is to yank out the USB cable and refresh the list. Then plug in USB and see what’s new. On Win and Linux machines SPJS tries to look at the VID/PID to show you an icon that it’s TinyG to try to help.

I’m not sure which port I’m supposed to be using. I pulled the USB and refreshed, and nothing changed. Here is a screenshot of what my JSON server is reporting…

Then you probably don’t have a driver for TinyG installed on your Mac and thus it doesn’t/can’t create a serial port.

OK. Can you help me with that. I know just enough about computers to be dangerous.

Thank you John. Nothing has changed tho. I tried to go into the tty.lpss-serial1 port and program the firmware for the card (which shouldn’t be needed, since it works fine on a PC) and it couldn’t find the card. Here are a few screenshots of chilipeppr and JSON.

And the JSON…

Keep in mind that your problem appears to be that your operating system can’t load the serial port at the USB level (maybe because of a driver). This problem is not ChiliPeppr or SPJS. If your OS doesn’t show your serial port, there’s nothing any app can do until your OS is showing the serial port.

One possible thing you could do is just run SPJS on that Win10 box you have and then you remotely connect to that SPJS IP address from your Mac that’s running ChiliPeppr.

What some folks do, like me, is run SPJS on a Raspberry Pi 3 that is always connected to TinyG. Then I just connect ChiliPeppr from my corei7 Win laptop to the Rpi.

OK. That may be the way I go. I’m also thinking of just getting a cheap-o PC that I can have dedicated to the shapeoko. I’m so new to this I’m assuming that the Pi 3 is kind of the same theory, but without the full on PC part. Thanks for the help.
