Flashforge Dreamer not detected by OctoPi #79

Closed MialTheMimiga closed 2 years ago

MialTheMimiga commented 2 years ago

After setting up OctoPi, and instaling the plugin, making a connection attempt doesn't return anything, nothing about a permission error, just no candidate

Using a Raspberry Pi Zero 2W, the printer has Wifi enabled as it was setup prior to setting up the the raspberry pi

here's an image of the set up, the red cable providing power 20220107_192959 (don't mind the candy cane, i don't know who put it there)

and a copy of the terminal

octoprint (1).log here's the log

Thank you for including the log - it's very hard to figure out what is happening without it!

Looking through the log you can see the section where it is trying to detect USB devices, for example:

2022-01-09 20:00:52,802 - octoprint.plugins.flashforge - DEBUG - detect_printer()
2022-01-09 20:00:52,804 - octoprint.plugins.pluginmanager - INFO - Loaded notice data from disk, was still valid

Notice how it only finds the one device, which according to http://www.linux-usb.org/usb.ids is 1d6b Linux Foundation USB 2.0 hub

The fact that it is not listing the Vendor ID and device ID of the printer makes me wonder if somehow the printer is not connected to the Pi? Maybe you have the power connector in the USB Host/OTG port and the printer connected to the (USB) power port?

it occurred as a possibility to me but i never tried to go through with it cus i don't fully understand linux/ raspberry pi

Update: After Swapping around the cables, that infact did the trick Update 2: had a bit of a slip up withadding permissions, my ssh client can't correctly paste spaces in it's text editor, but i got it fixed when i noticed it, and it's working fine, thank you
