User Interface Software

WebUI

What happened?

I'm not sure what happened. After the machine completed a job, the pendant displayed "NC." However, the machine remained responsive. After I rebooted the Machine, The pendant has a black screen and the controller's web GUI is not coming up. The ESP board has a red light, but I'm not sure if it was always on.
power off for 10 minutes and unplug the controller
GUI came back on (Black screen on the pendant)

[MSG:ERR: mount_to_vfs failed code 0xffffffff]

Try new sd card and same error new sd work fine on PC

Not sure if its realated to anything but the past couple of runs
The machine would freeze in place for a few secounds and then continue to move

Let's start with the pendant.

I'll assume the pendant is the FluidDial, if not let me know what it is.

It appears to be broken. It should have some display regardless of the controller. Disconnect it from the controller and power it from the USB. Reply with what happens.

[fvargasfrank]

Just connected it to usb c, windows says unrecognizable usb and it still shows black screen, probably went dead.

[fvargasfrank]

The sd card works now with the old one, nothing new just left it off for the night, I ran a job and the machine still freezes.

Try changing this to I2S_STATIC in your config file.

stepping:
  engine: I2S_STATIC

Send $I at the console and show me the response.

[bdring]

Try running with I2S_STATIC and keep a FluidTerm connection open the whole time. If you get a lock up see if there are any debugging messages there.

The SSID=Not Found:Status=Connected is odd.

This is what I notice when everything freeze I see this

[MitchBradley]

Aha, an out of memory condition. That is hard to fix. It can sometimes happen when there is a lot of other network traffic that ends up consuming a lot of memory inside the Espressif networking code. There is not a lot we can do about it in the short term. One thing that can help is to use a smaller SD card. High capacity SD cards use a lot of memory because they have very large chunk sizes on the card. Another thing that might help is to put FluidNC on a dedicated WiFi router, so it is not subjected to traffic from other things on the network.

[MitchBradley]

On the topic of SD cards that work on PC but not on FluidNC: Modern high-capacity SD cards store data in large chunks, up to 64KBytes in size. That chunk size affects the amount of memory that is necessary in order to read a file from the card, even if the file itself is small. 64KBytes is a small amount for a PC that has many gigabytes of memory, but it is a lot for an ESP32 that has a total of only 520 KBytes, of which 80% is already used for other purposes before any SD card accesses are attempted.

[fvargasfrank]

I will get a 4gb sd card and go from there, will probably isolate the wifi by putting it on a private VLAN with only access to my phone and pc
