Can't upload .gcode, getting an error

[briskspirit]

Hi.

After some time I can't upload big .gcode files through web(one file is ~4.5Mb and other is 12Mb) Checked my SD card - everything is ok(original that was with Duet Wifi)

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.02(RTOS) (2018-12-24b1)
WiFi Server Version: 1.21
Web Interface Version: 1.22.6

Try updating to new web control.

I was having issues myself and had to reset the machine to get the file transfers back up to speed, since the update I haven't had an issue.

Also run a M122 to see how good your WIFI connection is.

Thus improved greatly for me when I updated to the v1.22 wifi Server

Also, send M39 to check the cluster size on the SD card. It i's less than 32kb, then get a new SD card, format it to 32kb or 64kb clusters, copy the old card to the new cared, then use the new one.

@dc42 That card was with Duet and worked fine. New web interface helped to solve this error.
