PrusaLink to USB

RE:

Does it happen if you reslice it without G2 Arc Fitting ?

Can you share the currently used gcode?

Another idea - replace pendrive?

RE:

Haven't tried it without the G2 Arc Fitting. 36hr print, not repeating it, it did finish, with some defects from the pause, but for it's purpuse they aren't noticable. This pause happened many times.

I'm not using the Prusa USB, Higher speed samsung USB, uploading via Prusalink is quicker with it.

Hasn't happened on any other prints yet.

RE:

I can hear the nextruder gears clicking. Maybe jam detection is causing this. Are you printing PLA? I doubt this is a firmware bug. If you still believe it is then you need to open an issue on github: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues

The clicking is the sound of my keyboard with Prusa CS. This is PLA.

Ah OK. LOL. Anyway, I think it's a filament jam causing this. I don't print a lot of PLA anymore (especially on a Core One). Try turning off filament jam detection. 

RE:

There was no clicking like a jam would indicate, no errors detected, why would the printer pause. Typically is just keeps on going with a jam. How does it unjam itself over and over again without extruding. It just pauses, waits, then continues. CS was thinking it was acting like a power loss, no power issues were occuring. To me seems like it was waiting for data to be transmittted, also the ETA of the print kept lossing time continously, even when it was printing, not just the pauses, the preview of the model screen was also blank. The ETA times on the main screen and preview screen also didn't match. Seems alot more logic then mechanical.

The binary g-code would be on the USB. Yes is gets streamed to the firmware. Perhaps the USB key has a problem? Have you tried swapping it out? This is what I use in mine: https://www.sandisk.com/products/memory-cards/microsd-cards/industrial-microsd?sku=SDSDQAF3-008G-I

I've been running SAMSUNG FIT Plus 3.1 USB Flash Drive, 128GB, 400MB/s, formatted for FAT. Flusher fit and much faster than the Prusa USB.

RE: Firmware Bug: Random Print Pause, Time Loss

I'll give the scan disk a try, simpler to deal with FAT on smaller storage anyway.

I have two of these SanDisk Industrial MLC MicroSD one in the buddy cam and one for printer. The printer uses a very low profile USB adapter  But then maybe Prusa should get away from 15 year old tech (the Buddy Board) STM32F407VGT6 and something a bit more modern with built-in eMMU
