Can't write to SD card

[mlangner84]

Hi, first of all thank you for spending your time in putting this together. I just got the QIDI X-Max and was really disappointed that the software would not just connect via Ethernet. I found your script and it seems to be able to compress the file as well as connect to the printer. The issue is that it can't write onto the USB stick. Here is the creation of the compressed code and the error code:

input file:.\gear.gcode file:gear.gcode dir:. open input file .\gear.gcode ok open output file .\gear.gcode.tz ok convert done! X_min:5.000000 X_max:163.324005 Y_min:111.676003 Y_max:138.324005!

INFO:main:3D Printer Xmax IP address: 192.168.5.244 INFO:main:Start write to SD: M28 .\gear.gcode.tz INFO:main:Start write to SD result: Error!Cann't create file .\gear.gcode.tz INFO:main:File Position: 0 INFO:main:Sending File Chunk result: ok

Is there any requirement for the USB stick? I have tried the original one and a clean FAT32 formatted one. Do you have any other idea what could go wrong here?

Thanks!
