try closing that browser and opening a new one.
and it’s not going to show a secure connection because there isn’t a https cert on the maslow
I’ve now tried several browsers on that laptop and the issue is still appearing (Chrome, Firefox, Windows).
I figured out that when I connect to the Maslow by my Samsung Smartphone that it works without issues, with Chrome or Firefox.
So there must be a problem with the Laptop Configuration. Could it be because of the hardware Wifi which is an older one?

I think that this is a good theory for sure!
hi All,
i’ve finally got my Maslow calibrated / anchor placement sorted, been trying to get a simple first cut but having constant issues with loss of connection as described in this thread, (I’m running latest firmware etc ) the maslow sets off and starts to cut etc but pretty much before a minute has passed the cnc will stop and a moment later i get the ‘please reconnect me dialog’ . is there a way of connecting via a long usb cable ? if not can this be something that can be incorporated in the next update ?

You can connect via USB as is, but I don’t know if anyone is really doing it. Most folks who have talked about it have ended up finding it easier to sort out the wifi issues.
When you are asked to reconnect does the machine start up in the “Alarm” state or does it say “Idle”?
That will tell us if it is restarting or just losing wifi connection.
I am having similar problems. Is it possible to add an external Wi-Fi antenna to the board? Can I plug something into the USBC on the board for this? If not. On a future board would it be possible to add an antenna plug?

That’s an interesting idea. The ESP32 does some in an external plug version so it wouldn’t be too hard to have an external antenna option. I’ll keep that in mind for a future option!

Please do, I think there are a lot of people who would benefit from it.
it doesn’t need to be a big run of boards to test the market

Ok, so when I lose connection and click the helpful “reconnect me” popup it wipes everything, must retract and extend before trying to calibrate again. The maslow isn’t saving states
Also I moved from my driveway to the back yard which is a straight line of sight 20 feet from our house router (newish and pretty good) To improve the signal but it is still glitching out. I can often see the maslow on the router list of devices with an IP address but it the computer still does not connect even when the router sees it.
Currently firefox on a linux ubuntu mint dell laptop.
Here is the log as it restarted
Maslow-serial(13).log (2.8 KB)
it did suggest that maslow? was corrupted this time which is new for me and that I should restart the machine.
Which version of firmware are you using? It looks like it has the wrong version of maslow.yaml file, Sometimes a power reset can fix that weird erroring. Try connecting directly to the via wifi instead of via your home network.
I think the error 3 in this case was a temporary thing. I am using 1.12 and uploaded index and yaml from the same batch.
Thank you for your help.
This sounds to me like it’s not actually a WiFi connection issue, but that the machine is restarting. Restarting will cause the WiFi connection to reset, but that is a symptom not the cause.
Are you seeing any error messages? How stable is the power connection?
Power seems very stable. It really seems to be a connection problem? Only the “reconnect me popup and then the serial stream seems to be wiped and start new.
Does it start back up in the alarm state?
I don’t know. I will check next time I am playing with it. What is the alarm state? I see the button but i don’t think I saw it do anything?

the fact that you see the alarm says that it’s on. With 1.12 and earlier, it
sets that when it starts up.
to see if it’s restarting, a USB cable with a terminal program to catch the logs
will work on it.
@bar, would it be useful to have a boot counter that we incriment each boot and
display as part of the output of $TEST??

error 3 means that it tried to read or write a parameter in the yaml file that
isnt there.
if it happens once with a new version, it could be that there is a new parameter
and it’s checking if it exists.
If it happens a lot, or repeatedly, it could be a corrupt yaml file.
I’ve sometimes seen problems like this that show up every other boot.
The esp board has two banks of flash (so you can update one without risking
breaking the system as you are running on. I’ve wondered if there is some
condition that only manages to write a maslow.yaml file to one of them, so each
boot you switch between them (which would be a smart recovery mechanism),
causing errors/parameters to go away when you boot and come back when you boot
again. ???
