[SKR 1.4] WiFi upload: "Please use 8.3 filename only." As the title describes, I have put a lot of work in getting the printer controls to work over WiFi with the TFT35 v3.0 screen from BigTreeTech, everything works, but when I try to upload a gcode file through the web interface I get this error no matter what kind of filename I use. From what I understand this issue was fixed but it stays persistent in my setup. [attachment 116432 Screenshot2020-08-17at10.43.24.png] Does anyone have a solution to this issue? From what I understand this is an ESP3D issue, but everywhere I look it says this issue has already been fixed. I just can't find the solution. https://reprap.org/forum/read.php?415,876183,876183#msg-876183 Tue, 14 Jul 2026 06:22:41 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?415,876183,881222#msg-881222 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,881222#msg-881222 noobontour024 Firmware - Marlin Fri, 05 Feb 2021 04:27:21 -0500 https://reprap.org/forum/read.php?415,876183,881209#msg-881209 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,881209#msg-881209

Try formatting the card as fat32 or some such. I use octoprint so this is a guess.]]> dant220 Firmware - Marlin Thu, 04 Feb 2021 17:24:55 -0500 https://reprap.org/forum/read.php?415,876183,881141#msg-881141 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,881141#msg-881141 beratuzun Firmware - Marlin Mon, 01 Feb 2021 17:05:35 -0500 https://reprap.org/forum/read.php?415,876183,876824#msg-876824 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,876824#msg-876824 Ohmarinus Firmware - Marlin Tue, 01 Sep 2020 09:30:22 -0400 https://reprap.org/forum/read.php?415,876183,876348#msg-876348 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,876348#msg-876348
Anyway, my issue persists and flashing new firmware on the ESP-01S didn't help. If anyone knows how to approach this issue I would be grateful!

Can it be that '#define LONG_FILENAME_HOST_SUPPORT' has anything to do with it?]]> Ohmarinus Firmware - Marlin Thu, 20 Aug 2020 13:18:06 -0400 https://reprap.org/forum/read.php?415,876183,876190#msg-876190 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,876190#msg-876190

... is it the pure filename (e.g. "NNNNNNNN.EEE") or maybe the path or connection-naming added?

Using a filename with 8 characters and 3 extension characters does work for the upload. But the main thing is that I haven't found anyone else with this issue so I'm worried that this error is only hitting a few people. I'm starting to think maybe it's not the TFT35 but it's maybe the ESP3D.bin file I used, it may not be the latest and maybe I should flash the more modern .bin file with a FTDI programmer?

I'm on a macbook so I cannot use the windows FTDI flasher from BigTreeTech sadly :S]]> Ohmarinus Firmware - Marlin Mon, 17 Aug 2020 06:49:08 -0400 https://reprap.org/forum/read.php?415,876183,876188#msg-876188 Re: [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,876188#msg-876188 VDX Firmware - Marlin Mon, 17 Aug 2020 06:28:35 -0400 https://reprap.org/forum/read.php?415,876183,876183#msg-876183 [SKR 1.4] WiFi upload: "Please use 8.3 filename only." https://reprap.org/forum/read.php?415,876183,876183#msg-876183
