Has anyone tried running the json server on a Raspberry Pi? There seems to have been no report on such usage so far.
That’s why he added turning verbose output off on spjs because it was dragging down the raspberry pi.
I am getting tired of turning off and on the computer plus lacking the ability to control the relay on/off the laser cutter. Now that my desktop needs a new HDD, I am thinking of buying a RPi instead.
Sounds like what I am planning for my rpi as well. Hopefully now that rpi+ is around, I can get the rpi for cheap.
I am using it on a pi, it runs like a dream.
I had a few issues at first but it turned out to be the usb extender cable I was using, so I relocated the pi to be in the same box as the tiny-g with a 30cm cable and now it works great. Also, if I hit a limit switch, the TinyG resets and I find I have to reload the json server.
Biggest job I have sent it is about 9000 lines of G-Code with 6 or 7 tool changes. Lots of drilling, milling, chamfering etc. Didn’t fault once.
I assumed everyone else was using them as well. I have a couple of spare piface boards and I am investigating using them to control other things like coolant pump/mode. At the moment one buttons on the piface kills the json server and one button launches it.
I love hearing that it’s working well for you! Will have to investigate the resetting of the TinyG stuff. I have not tested hitting a limit switch.
Would love to see a video of some of the jobs you’re running and your setup. I think it would help others understand what a good model ChiliPeppr and Serial Port JSON Server are. This model is kind of a first for the CNC industry and I think it’s a game changer.
I should be able to accommodate that, I am doing a rebuild on my z axis this weekend ( I find it to difficult tramming it at the moment.) But when I am done I will do a video up.
Can I just say, the biggest game changer is being able to hover over g-code and see a description of what it means, that is awesome.
I’m glad you appreciate the hovers. I wanted those badly as when I was new to the CNC game I had no idea what each Gcode item meant.
Hover is good. But go to this gocde location = awesome for resuming bad cuts. Actually, I love everything. 
My favorite 2 features I never had in other apps I’m using a lot. 1) The zeroing out of the Z on PCB’s using an alligator clip by using the “Test Probe” run in Auto-Level. 2) Using the Motors Energize / De-Energize button in the TinyG widget to do a tool change without losing my axis position.
Alligator clip method?
Yup. You connect 2 wires to TinyG’s Z Min port and put alligator clip on the endmill. Then push a wire against your PCB. Hit “Run Test Probe” and it lowers the Z to the exact spot the circuit connects. You are at a perfect Z zero.
I see. That’s awesome.
