That is an S3 board. Not sure they are fully supported yet.
The only time I noticed an issue is when a USB is connected. How else are you guys triggering these issues. What sort of Gcode?

Have you not had any networking issues at all? Or not using anything but ap?
The ESP01 has to send ever few bytes at a time over gcode to Marlin amd Marlin writes it to the sdcard. The gcode uart connection is the bottleneck.
The esp writing straight to the sd card is a lot faster. The esp01/esp8266 should be able to do that fast too. But the esp01 doesn’t have enough pins for its own sdcard.

Just AP and wired. I have a lot of devices available near my machines.
I am learning so much with this project. Thank you. It makes perfect sense now, but it honestly didn’t before. Very rewarding.

So for some reason ap mode is not having a problem. Which they find odd on discord as do i. I will get those esps on sunday and see if the issue shows for me. I will not be able to do much, but i want to dive in anyway. I really want to do a config much like the one where newtech did and used tmc2160s but not sure i can swing that for a while. I will do what i can. Ap mode should need more resources as it controls everything.
I was also looking for any way to build it on my own, like you roll up the fw currenly but dis not find much on github.

4.3A drivers! What are you going to do with that?? Mr Dring has an external stepper board in his tindie shop that would be perfect for those. The 2209 we use can go about 3x higher than we use them if you just want a little more power. Other than that the 5160 are slightly more powerful than the 2160, but way easier to get a hold of (cheeper).
They both need to control the machine directly, they both need to serve the webpage, what is the big difference between talking directly to a device vs talking to a router? As in what is the difference and why would one cause a memory issues. Is it like old school network collisions in the STA mode, it has trouble sorting like cheapie network hubs used to?
I would like to do more testing but I have no clue how to test network issues at all.
The source is there, I had to compile my own until the CS changes got merged. There is the fluid firmware, webui separately though.

Lol nothing. I did not realize they were that beefy! I really want everything laid out like he did with the plywood and lasering. Kinda weird i guees. That is why i wanted the external steppers.
Also i did alot of reading on this. I think it was Bart that recommended station and not ap because something does a liveupdate.
Not sure yet. All i have to go by is what Jaime posted and what i have read in discord, etc. I shine in networking. I am old and old schooled 
Honestly i would love to use my ramps board, but it is not supported it says!

Oh the page itself not an actual networking thing. I am so clueless to this.
Do you have a link?

Yes, the PCB antenna is not always tuned to the right frequency and can have a weak signal even when located right next to the access point. By placing your thumb on the antenna you can easily offset the tuned frequency of an antenna. My esp32 has difficulty connecting to an ap but when I place my thumb on the antenna it connects right away, also the ping responses are much faster and more consistent.
Another way to offset the frequency is to place a thin strip of mylar on the antenna, such as from the mylar bag the esp32 was packaged in. With this small strip of mylar in place this esp32 easily connects to the network and doesn’t have any more issues communicating with the ap.

Is there an inexpensive tool to test the frequency or do you just watch the power with a wifi tool?
This could be a reason to use the $10 official espressif esp32 instead of the imports.

You mean something like a spectrum analyzer based on a low-cost software defined radio?

It really is not going to be frequency. Running out of memory is something either not setup correctly or driver not correct. It is interesting there is an espressif esp32. .my research did not turn that up. Some of the things i want to see is if there is a way to drop the entire dhcp part and save memory. I was looking for the way to compile in case there is a way to go back to the old network stack or to even drop parts of thenetwork stack to save space.
So my mind has a little different obviously because steppers are mounted but channels cnc’d for wiring and labels lasered, just something kinda neat.
But here is his:

Wifi and Bluetooth | Wiki.js if you set static mode maybe that helps? The warnings on this page are all against AP mode.
What is his youtube link, https://www.youtube.com/channel/UCG4CjsyrsemzvK3voin0KAw doesn;t seem to be the right one.

I had seen that.
Whatever you do, do not use those drivers. minimum is 2.3A. He says he has had no problem with that but that can’t be correct. if we turned the 2209’s up to 2.3 A we would melt right out of the stepper mounts and probably melt a stepper. We use 0.6 to 0.8A still silent, much cheaper and ultra fine current control. Those as 2.33A next step up is 2.57A. But that can not be right if it did not melt his prints. Something fishy about that whole setup…oddly he has wifi issues as well. He also is not using auto squaring in the firmware.

Gosh, I guess LR3 Pro needs Alu stepper mounts?

Testing the file upload, I have a file from OpenSauce 1,512kb, fails to upload. Low Memory error, If I try it again it tries much slow still errors out. Looks like for larger files you still need to use a direct SD transfer.
