4 years ago Thanks for the detailed debugging - if it is no more than a year old, it is probably a Finder v2, either way it should be detected.

4 years ago Hi! thanks for getting back to me so fast. This is a brand new Pi, so I think 4B? I do not have it connected to hub. The Pi goes straight into the USB A of the finder. There is a USB "B" port as well. Not sure if it matters which one I use? The printer is on The cable is indeed plugged in. The printer is only connected to the Pi. I wll unplug it, and do a check again to see if issues are the same (if so, then it's not the printeR)

4 years ago perhaps I need to use 12?
Mrnt
commented
4 years ago Yep - 12 is the usb connection for the printer to act as a slave which in this case it is since the computer/pi is the usb “host”. The other port allows the printer to act as a host to a usb (slave or client) device such as a usb flash drive

4 years ago Ah ! ok. I ordered a USB-a to B cable. I think we can close this ticket. It might be a good note for your documentation if you feel so inclined. :) thank you for your help, I will re-open if I still have issues.
Mrnt
commented
4 years ago Sounds good. I wonder whether the usb A port on the printer would deliver enough power to power the pi by connecting it to the pi’s usb C port. Probably dodgy since I think pi 4 takes 700ma or so and regular usb A ports IIRC rated 500ma max

4 years ago Sorry, I think the last version broke the ability to make the initial connection after clean install and hence the lack of feedback on what to do next (enable USB permissions). I'm about to release a fix for that and the printer profile issue you identified.
Thanks for your patience.

4 years ago I just put up the new version (v0.2.4) if you want to give it a try. In theory OctoPrint will notify you that it is available, but that can sometimes take a few hours. You can just go an reinstall it and I think that will get you the latest version.

4 years ago Also - I see the finder respond to using the "Upload from SD Card", but it never sets the temperature or actually starts the print - but the finder's display seems to indicate that it is ready to start printing. If you have any insight, not really a bug - just trying to sort it out. :)

4 years ago The USB permissions thing is that octoprint does not seem to have read/write access to USB devices by default, so you have to explicitly add it (per the instructions that the plugin displays in the terminal window).

What kind of file are you uploading to the SD card? Is it something sliced with FlashPrint?

TBH I didn't spend a lot of time looking at why this is, but I'm assuming that only root has read/write access by default and other users (eg octoprint) have to be granted access explicitly. The udev rule grants permission to any user/process on the device.

4 years ago This should be resolved. Combination of wrong USB connector and bug not allowing for printer detection resolved in 0.2.24
Hi! I'm using a regular USB cable (USB-A to USB-A) to connect from my Raspberry Pi with OctoPi/print to my Flashforge Finder (it's less than a year old, so I'm not sure how to tell if it is a v1 or v2). Anyway, Octoprint does not recognize the device. I turned on debugging, and I get this:
