I haven’t even started wiring up a TinyG for my OpenBuilds Ox yet, but I have 2 questions:

  1. I have an old PC lying around, but it may only have USB 1.0 (like I said it’s old) and I’m wondering if USB 1.0 will be fast enough to drive the TinyG board (probably via #Chilipepper ), or will there be hiccups due to this slow USB 1.0 port?
  2. Has anyone used a Raspberry Pi model B as a host for a TinyG? Over SSH or remote window? Using Chilipepper?

Usb 1 should be fine since that is faster than 115200 baud. I would recommend you spend the 35 and get the rpi 2. I use that and love it since I also get the gpio from that board. I use Ben’s gpio server to control my fans and lights.

@jlauer I have a Pi2 (bought it over a month ago and haven’t even booted it yet–too busy!). I also have 2 v1s that I was hoping to use; is there any reason to think a v1 Pi would be too slow for this purpose?
PS - thanks for your work on ChiliPepper! :slight_smile:

I use the v1 Pi without trouble, but ALL it does is the remote serial port. I can connect to it in many ways, though anything graphical is pretty slow. I tried adding support for my 3d printer on it as well, and no go.

@Kevin_Hauser ​ for your 3d printer I’d recommend #Octoprint or #Octopi.

Thanks @SirGeekALot … I’ve looked at that as well as Repetier Server (because I like the Host form) … so far nothing is working on a basic Pi, though I realize I did have the GUI running on the Pi as well, so the tests might all be moot. SPJS is such a light little app that it runs fine, even with the GUI running. That why even though @jlauer encourages the use of a more capable board I really think the old Pi is more than enough for SPJS. I am pretty sure it would work well enough to run two separate CNC machines. So John, that means you did a great job coding it!

I’ve run Octoprint on a RPi v1 model B to drive 1 printer with no problems. But I have 2 Printrbot’s both running Marlin on Printrboards. If your setup is different (e.g. not Marlin) then your results may vary.
