Print Pausing (Thumb drive fail?)

I've been printing non-stop for like 2 days since I built the kit.

This current print I'm struggling through. It keeps pausing, for seemingly no reason.

I read about some filament sensor issues, so I disabled that, via the tuning screen but it keeps happening every 15-20 minutes.

If I just say "Resume" it re-heats, goes back to the failure point and then pauses again, (leaving a nice whisker of filament too) BUT if I yank and re-insert the thumb drive before Resume, it picks up and continues printing.

I'll try the old "Turn it off and back on again" before the next print, as well as swap-out the thumb drive. but any thoughts or suggestions for diagnosing why it seems to be losing access to the drive?

When someone asks you if you're a god, you say, "YES!"

RE:

Yep - I have been seeing the same thing here.  I have been twiddling with fining the right USB drive configuration and tried the extra large FAT32 solution.

I am going to re-run a test changing how the thumb drive is configured/partitioned.  I did not see the problems on other thumb drives....right now my Octopus print is taking 2 - 3x times longer than it should.

My long term plans is to get my new Raspberry PI up and running and use that over the flash drive with Octoprint.

right now the pause is about once very 30  - 40 seconds.  I am using the non-binary g-code setup.  It seems the longer into the print the more often the issue happens.

RE: Print Pausing (Thumb drive fail?)

Side note: Not sure what the problem is - but about 1 hr into the print the printer kept pausing the print, resume, and pause again.

I stopped the print, and managed to generate a dump.

I built a second USB device, used Windows Disk management system and sliced the 64 gi drive to just shy of 32 gig and restarted the print. I am at the same point as the s/w was pausing every 40 seconds. Currently the new print is at full speed at 50% done.

I am not sure if the extra large fat32 partition was the fault, but a low level format on the drive worked fine. I don't think the issue was with the turned off PI connected to the printer.

Wow, I forgot about this post.

After this happened I got a new thumb drive, and have not had a reoccurrence.

RE: Print Pausing (Thumb drive fail?)

what size drive did you get?  I think size of the drive - or at lest partition of the drive might be one of the keys to figuring out what the MK IV likes.
