Elogoo Mars Pro - Can´t upload files

What is the problem?

Can´t upload files to Elogoo Mars Pro.

What did you already try to solve it?

I have already redo octoprint os instalation and Chitubox plugin.
Checked serial port configuration following the steps bellow:
sudo raspi-config
º Select option 3 (Interfaces)
º Select option 6 (Serial)
º Select option " NO "
º Select option " YES "
º Select option " OK "
º Select option " FINISH "

Don´t know how to check SAMBA configuration and if that is relevant to this issue.

Have you tried running in safe mode?

No. I´m not good coder. I don´t know how to run it in safe mode. I use PuTTY for Windows remote

Additional information about your setup:

OctoPrint version 1.8.6,
connected through /dev/ttyS0 baudrate: 115200.
The octopi is installed with octoprint plugins chituboard.
OctoPi: Raspbery Pi Zero W,
printer Elogoo Mars Pro,
firmware v4.3.4 ,
browser Chrome,
operating system Windows 10,

The priner is respectivel connected with jumper wires from the Raspberry Pi’s board GPIO board pins GND,Tx and Rx to the Elegoo board Gnd,Rx and Tx. As recommended here
(GitHub - rudetrooper/Octoprint-Chituboard: Added basic support chituboard based printers(Elegoo Mars, Anycubic Photon, Phrozen, etc.) to octoprint.)

The printer USB front port to be used with USB pens, is no longer connected to the printer board. With this setup, the internal USB A to USB A cable is conected to the Pi Zero W micro USB port through the OTG (micro USB to USB A female) adapter and to the printer USB board port. Elogoo internal USB A 5v pin is taped blocked to strip 5V from a USB cable.

Pi Zero W micro USB power port connected to 12V to 5V DC buck converter module connected to printer 12 V board.

Many thanks in advance for any help solving this issue.


Hello @PedroF !

I don't know if this is possible at all.
Usually you upload a file to OctoPrint then it's printed by OctoPrint line by line.

You don't have to be a coder. Click the blue words for getting more information.

I strongly recommend not to restart the Pi by power cycling it. That can have bad results like corrupted file structures on the SD card.

The Raspberry Pi Zero W is on the lower end regarding performance.
