I need to check but I think we are running 1.14 but I just found out we had a chain wrap or skip problem that blew the calibration so i am not opposed to upgrading to the latest this weekend.
I’d consider upgrading to latest firmware as it allows for coordinated z-axis moves on arcs.

I’d further recommend getting it all working again on using groundcontrol and make sure it works before trying to switch to webcontrol. I tend to be cautious and not try to change lots of things at once.

this looks like a very cool upgrade 3x faster with 4x more ram version available.
already backordered on all major suppliers web sites. lol.

I saw that this morning. There’s some compatibility issues reported that I’m sure are being worked on… so I’ll probably hold off getting one for a bit. However, I like the usb 3.0 ports as it would allow me to do some crazy things using a Google Coral stick.
I should have one in 4 days 
Thank you
backordered in part because they didn’t ship from England until the day of the
announcement, so the suppliers were all taking orders before they had any in
stock.

The OS is due for release on 7/7. This is why many retailers don’t have them.
Thank you
I’m running into an issue in the install process which I am 100% sure is a mistake on my part since I have no prior experience with Pi things. I am getting an issue saying that docker has not been installed:
Does anyone have any pointers about what I might be doing wrong? I am not using the prebuilt image because I want to do some development.
I ran into a problem on my development box where docker just stopped working and would error out on start (had to find it in the logs). I couldn’t fix it and just ended up redoing my entire SD card from a new OS install and it then worked. I’m not a docker expert so I’m afraid I’m not much help. Is this a new OS install?

This is the webpage the instructions were sourced from:
It is a fresh copy of Raspbian. I will try to install docker again in a different way, but I think I’ve corrupted my SD card so it might take me a while 
you can always do the prebuilt version and then modify the startup scripts so webmcp doesn’t automatically start.

After much head scratching I think I’ve determined that the Pi Zero W is not supported by docker. Is there any chance to run WebControl without docker?
Yes, just grab it from the repo. You’ll have to build all the dependencies and the long one is opencv/numpy but those are only used for optical calibration.

Thanks! That shouldn’t be too tough and might actually be exactly what I want.
Thanks for all the advice, and the awesome work creating Web Ground Control

Few areas that need work (in addition to the feature requests people have made)…
- Settings… still doesn’t seem to always promulgate to the controller when a change is made. It’s currently a complicated mess of software I wrote who’s existence annoys me. I’ve got to come up with a better way but at least it’s way better than my first miserable attempt at it.
- Client browser synchronization … disconnects/reconnects/power-save etc. can bring back a client thinking the system is in imperial units but is actually in metric…I think this will be an easy fix, just need to try it.
- Websocket API needs further cleanup and be made more consistent and ordered. I started working on it so it would be easier to manage additions of commands/features, but there’s plenty more to do.
- Optimization of network traffic. Currently all position updates are sent out through the websocket api even if there is no change in position. This loads the network and consumes processing power (and therefore battery) on the client. I intend to throttle updates when there is no change in position.
Unfortunately, life is life and a lot of my non-work time is now with the kids and my four motor design project.
