'//Disk init fail!\r\n'

Going pretty mad with this one as I’ve tried everything I can within the couple of guides and relevant issues I’ve found. Three fresh installs and a scouring of the issue reports on here, but nothing. I’ve checked issues other issues: #152 #235 #340

I am essentially having the same issue as #152. When I run a print file, I get an error like this:

mariner.exceptions.UnexpectedPrinterResponse: //Disk init fail!

I believe this to be down to mounting the virtual USB but I’m not sure where I’m going wrong.

This is on a Phrozen 4K Mini. My wiring is fine, hardware in general is fine (tried two boards, alternative power sources and get a different error in Mariner when I remove the jumpers entirely, which indicates to me that this is an issue with how I’ve set up my Pis.

Here’re my important files: (Mostly checked against #152 so you might see a few small bits not in the official guide)

[KTheMan]

(weird thing is the install script I used on this last-ditch effort - https://github.com/KTheMan/Mariner-Autoinstaller - should apparently have allocated ‘all available space’ to the virtual USB, but it looks like it’s been allocated much less).

Little bit of misinterpretation there. It’s expanding the filesystem of Raspbian Lite to the whole microSD card, and not the virtual USB unfortunately. If you’re looking to add a larger amount of space to that virtual USB you can change the size line 116 (in the script) from its default of 4096 (which shows as 4.0G when you ran df -h) sudo dd bs=1M if=/dev/zero of=/piusb.bin count={Your_Virt_USB_Size_Here}

Have you tried plugging your micro USB end into the other port on your Pi Zero?

I’m running into the same issue. Rebooting the pi fixed the issue for me, though.
