It sounds like you are not actually connecting all the way. You need to tell the device to “connect to this network as is”, and/or go to 192.168.0.1. Shown here, Jackpot3 CNC Controller - V1 Engineering Documentation
If you do not connect all the way the device goes back to the last source that had an internet connection. The jackpot does not have an internet connection so it kinda panics unless you tell it otherwise.
I did do this. It was the first thing I tried.
I have no idea how this could be the issue. I have changed to AP Mode, same issue with dropping connectivity. I have a very strong wifi signal in my shop. The router is 15 feet away with a clear shot to both the CnCs. I have them setup with a static IP, one is 192.168.1.120 the other is 192.168.1.124. When I do a clean install of Fluidnc I setup the connection at that time. I am including a picture of the connection as reported by Fluidnc Web Installer page.
For history sake I have been using this setup for over a year with no issues at all. I have been using MillMage for 4 months with the Jackpot 1 streaming everything with no issues. I did make sure the setups are exactly the same other than the IP address of course.
My tone is wrong, frustration rising to the surface, for this I apologize.
What I need to ask is what else is there for me to test or try.
I have reloaded Fluidnc multiple times, including downloading a fresh set of files from Gethub for the Jackpot 3.
Checked wiring, checked network strength, had Jackpot 1 connected and running alongside just to insure the network is solid, it is.
switched to AP mode, the dropping of connection behavior did not change, it did seem to have a quicker response time to inputs before it dropped out, found that to be interesting.
switched back to STA mode as this is my how I have always used my Jackpot 1 machine and want them both to operate the same.
Again I want to apologize for the tone I have set, one of the pleasures of being a part of the V1E community is this forum because it is always so positive!

No problem, it is very frustrating I am sure. We all default to the usual answers because it is the issue 99% of the time.
Take a look, if that is not. Send the board in with a little note and I will take a look at it and fix or replace.
Wondering if there’s a way to check “up time” and narrow down whether controller restart is happening when network connection is lost. Then, figure out if restarts are happening due to software faults, or stray metal (sharp eye @Joe_H 
) on the board, or loose power wiring.
In the past, I was chasing down “network issues” that turned out to be a loose power adapter cord going into the power adapter brick. That connection on my adapter brick felt loose (from use/abuse and insufficient strain relief in the past). I fixed by kinking the cable slightly, and then used some zip-ties through holes drilled into bottom strut to provide strain relief. That, and securing the adapter brick from moving, has helped prevent power cord from being jostled/yanked. Power has been solid ever since. i.e. less unexpected “network” drops for me.
Sorry if checking power cable, and checking if controller is power cycling was covered earlier in the topic already.
I couldn’t see “up time” (even if it’s relative milliseconds since boot) in the $ss output within https://forum.v1e.com/t/jackpot-3-will-not-hold-network-connection/53879/19
On another non V1E machine, I make the Steppers “sing” different audible frequency notes for a few seconds on boot up. Intent being to help me audibly detect unexpected resets/power-cycle.
What a set of eyes! The black line on the board was actually a strand from a wire sleeve that I trimmed off.
I went out and fired it up, then wiggled and pulled on all the power connections but it just stayed connected. After about a minute of this I stopped and was just looking at it and it dropped out.
I will package the board up and get it on its way back to California.
Thank you Ryan
So I have had this a few days now. I tried it a couple times. This morning I have had it running for several hours with no issues. I have disconnected and reconnected several times using AP mode. No issues.
I am going to load up some gcode to have it run for a few hours to see if that changes anything.
I am I think I will update the webui and firmware just in case, after the gcode test.
I have a second Jackpot3 on its way so please keep that one as long as you like. I can tell you I was having issues with my wiring, (I had them crossed up) I don’t recall having the connection issues with the board during the trouble shooting phase. I know it has ran for over 3 hours a time or 2 before it drops off. There are other times when it will not stay connected for more than 30 seconds.
I have a Lowrider 4 with a Jackpot1 that is about 3 feet from the new one. I connected it to the network during the trouble shooting phase, it was rock solid, never lost connection once. The new jackpot3 was constantly dropping off. I normally use STA mode but did try AP a few times and it dropped that also.
Could it be something to do with heat? Seemed like the longer I used it the worse it got over time.
I did become concerned about the wire that drives the fan, I actually removed the lid and disconnected the fan wires, did not change the Jackpot’s behavior.
Thank you for taking this seriously
That is why I did not just automatically erase and reflash. I wanted to test exactly how you had it.
The drivers stayed cool, just sitting on my desk, even after running for a couple hours. The ESP32 is cooler than most. Heat wise it looks great. (I do not use a fan or heatsinks on my JP3, we didn’t at RMRRF either).
I have had no issues with it at all. I will erase and ref lash tomorrow and run it all day. If I can still connect by the end of the day I would say it is fine and it must be on that end somehow.
Is your test client in family with Bob’s? E.g. OS, type of machine, Browser type and version?
Good Question.
Bob, I don’t see it in the thread here, what are you using to connect. Windows/mac/android/iphone? What browser specifically?
Agreed,
Sounds reasonable.
The second Jackpot3 should be here on Saturday, let me see if I have any issues once it is installed on the machine. That should shed some light on the situation.
Ok
The new board is installed and we are having the same connection problems. That tell me the issue has to be on my end. What I have done so far trying to run this down.
Changed the cord running to the machine
Changed where it is plugged into the wall for power
Removed and reassembled all the power connections on the board
Had a short length of power cord I had made to run in the drag chain, removed that went directly to the wall plug.
I know my network is solid, the problem has to be somewhere else.
Power supply? I am thinking of ordering a different power supply as I am fresh out of ideas.
Determined to figure it out but running out of ideas.
Ryan, I apologize for wasting your time working on the board I sent back, it appears it is not the problem.
Pictures and details.
You’ve said what you tried but I haven’t seen the specific details we need to keep troubleshooting.
What model of computer? What OS? What wireless card? Did you do the setting to prevent the OS from dropping a connection without internet connectivity?
When it is connected and disconnected there are details we can glean from the OS to help troubleshoot. For example I think in another topic we asked about getting results from a command prompt.
Pictures of the setup and the environment the machine is in, screenshots of the software when not working.
Pictures and model numbers of the replaced and replacement power supplies or other parts.
Here are some observations:
Is the antenna (top of the top left component) sticking out of the case? What does the antenna part look like?
What’s going on with the multiple power wires?
How are you determining that it’s not “holding” the network connection? Are you connected via the WebUI and it’s disconnecting or something else? When it does disconnect can you reconnect the WebUI or do you have to power cycle the Jackpot?
I would also try connecting via FluidTerm while it is running. It may make it more clear what is actually happening.
I will do my best to answer all the questions.
Computer is a SRESNAIL Windows 11pro Mini PC, 16GB RAM & 512GB M.2 SSD Tiny Desktop Computer, Alder Lake N95 CPU, 4 Cores 4 Threads Mini PC, Support 2.4G & 5.0G WiFi, Gigabit Ethernet Black. This is the computer I have been running my other LRv4 with the Jackpot1 for over a year that is rock solid.
Wireless card is built in, it is a Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC
I do not remember changing the setting to prevent the OS from dropping a connection
The network is a static IP, the router is mounted up high on the wall about 15 feet straight line of sight from the machine. Original LRv4 is about 4 feet away from the new one with a solid connection, never have had any issues with it.
I can get you whatever you need from the command prompt but will need direction on that one.
Both machines are in a climate controlled shop with a dedicated power meter for this building.
The Power supply was purchased from Ryan a few months ago. I ordered a second Jackpot3 for a seperate project, used it to rule out it being the board.
I am running MillMage streaming the code to the machine. This is the only way I have ever used the older machine.
Will get pictures here in just a few.
Multiple power wires are power supply and wires going to the fan.
The connection will just randomly fail, with ether STA or AP mode, doesn’t seem to matter how the connection is made. I mainly use MillMage however with I log in to the Fluidnc web page the behavior is the same. once it looses connection I have power cycle the Jackpot to get back up and running.
It frequency of drops do seem to be increasing as time moves along. Makes me wonder about heat buildup however the power supply is cool to the touch.
