RE: USB error mid print
Corycwagner: Did you try to disable PrusaConnect? Didn't that help? Please let me know!
An interesting theory about the hardware. I can see that the cabeling is a bit ... suceptible to EMV (seems unshielded?), which could be a problem for high frequency serial ports like USB. I could also see that maaaaybe 6.0.0 is causing a bit more stress on the system due to the new programming (more high frequencies?). But that seems a bit unlikely(?).
I think that fact that I haven't seen a single problem since I was disabling PC shows a clear workaround for now and might indicate a problem of concurrency due to multiple clients accessing the same USB device.
Again - it might be conceivable that there are errors on the serial line which are gettig worse with the increase of access + high frequency EMV, but I would think that the SW problem is more likely.
RE: USB error mid print
Added a comment to the bug. Nice model corycwager btw!
RE: USB error mid print
I have disabled connect and link. Too early to tell if it worked or not. I'll keep you posted. Thanks for the tip!
RE: USB error mid print
Awesome - thanks!
RE:
After disabling PrusaConnect I still get an USB error after a while, also tried disabling phase stepping as well as WiFi with the same result.
I downgraded to 6.0.0-alpha and I have now been able to perform a few successful prints, I have however not tried printing the same G-code that kept consistently causing this hang-up. I'll try doing that tomorrow.
Something which might also be worth investigating is that when phase stepping is disabled the preview images load very slowly when using third-party USB stick. I've tried quite a few different USB sticks, formatted correctly as FAT32 MBR as described in the knowledge base article. This effect is a lot less noticeable when using the stock USB stick.
Below is a video to get a better idea of what I mean.
RE: USB error mid print
Unfortunately, even with both PrusaLink and PrusaConnect disabled, the print failed in less than 2 hours. Sigh. Back to the drawing board.
RE: USB error mid print
Thanks for testing. Darn. Sorry - after it worked for me I thought it was it.
RE: USB error mid print
Any chance we could rule-out the slice as the problem by me sending you the sliced model and having you print it? If you get a failure, the issue is with the slicer/model, if you don't, than it must be a hardware problem with me.
RE: USB error mid print
Same issue, it never happened until 6.0.0
RE: USB error mid print
I downgraded my XL to 6.0.0-alpha and after this I was able to successfully print the same g-code multiple times which previously kept failing. Phase stepping as well as Prusa Connect were all enabled.
Attached below is the g-code file.
Quarter Baseplate HBM Ladekast v1_0.4n_0.2mm_PETG_XLIS_1h56m
RE: USB error mid print
After 2 weeks+ or so of printing far too much (I think the printer was at least 12 hours busy every day) - multi color and single color, PETG, PLA, today I finally got a USB read error again. Needless to say there must be now 30-50 new prints on the stick.
So - Prusa Connect is not the full story here as you pointed out already.
I will next try to empty the USB drive, re-emable Connect and see if it happens again.
And if everything fails I will see if 6.0.0.0 alpha does the trick. *sigh*
RE: USB error mid print
Just to chime in, I also am now seeing this pretty regularly where my print will stop after 6 hours or so and say the USB had an issue. This last time, I didn't even have to touch the USB. I just hit continue and it picked back up. This started after I got the 6.0.0+14794 firmware.
RE:
Ok yeah...this is really becoming an issue. I just lost a 10 hour print due to a layer shift that occurred when this happened. I think I'm going to revert my firmware til this gets fixed.
To be clear, I am not seeing this with any given specific print. Sometimes it happens, sometimes it doesn't Given the other posts, this smells like a bug in the 6.x firmware that is still present.
