Had been playing with ChilliPeppr running on an old Lenovo (32 bit) notebook with Ubuntu 14.04 LTS. That worked well, but wanted to set up a 64 bit system to use with the CNC machine going forward. I finally got a video card that works with 3D acceleration and installed Linux Mint 17.1. That is all working well, bCNC connects and works just fine with the GRBL / Arduino UNO. But when I tried the V 1.88 AMD 64 bit JSON server I have a problem.

I select grbl for the buffer and click to connect. I get the initial response from GRBL v 0.9 in the serial console and then ChiliPeppr comes back and says that I need to select grbl for the buffer and has unchecked the JSON server connection. Rinse and repeat with the same results.

Finally I downloaded v 1.88 32 bit version of the JSON server and that works fine, so I was wondering if anyone else has seen this particular problem. Did I maybe miss something during the installation of the dependencies for ChiliPeppr?

Again Linux Mint 17.1 64 bit running on an AMD 64 bit system, but 64 bit JSON server doesn’t appear to be working properly… 32 bit JSON server does.

I found a mention else where for a different problem that Chrome appears to have some issues with 64 bit JSON server. So I tried the latest Firefox and that works OK with the 64 bit JSON server. But the graphic rendering is poor so if I can’t improve that then I’ll just run with the 32 bit JSON server and chrome for the time being.

I tend to come down hard against Firefox, but that issue surprises me. Firefox uses Chrome’s WebGL engine to render 3D on Windows machines.

Yes, I was a bit surprised as well. What was interesting was that after I had successfully run with the 64 bit JSON server with Firefox I went back and it now appears to be working with Chrome as well, even though it kept disconnecting earlier. I guess more testing over the next few days to see if the problem surfaces again.
