XL pauses does nothing for over 10 seconds and oozes all over the print
i keep getting strange blobs on my prints that made no sense. I checked the gcode and the nozzle movements in slicer and there was no retraction happening at those blob points.
Then i sat and watched the machine for a while. what is happening is the machine will be in the middle of a movement then hang do nothing.
the nozzle will sit over the print with the blue light flashing on the tool and do nothing for over 20 seconds. it acts like the software has crashed.
then it will suddenly the nozzle light turns green and it restarts and continue having left a nice fat blob on the print. i also went back and could see the same blobs occuring on support material of past prints.
it seems to be a new thing since going from 4.7 to 5.1 firmware.
so i googled the same issue as other people are having with the multitool XL
the recommendation was turn off all sensors and turn off prusalink.
i turned all the filament sensors off and disabled everything else.
next people thought the issue was with the USB drive. so i sprayed i with Deoxit and i put a fan blowing on he USB and LCD front panel
because there was threads on reddit about the USB drive getting hot.
i then ran the same gcode. the machine hung again but in different spots, showing the machine is infact somehow crashing.
when i went to go stop the print after yet another failure the machine RED screened crash.
URG... i have had maybe 4 good prints with this machine it has been as cursed as the MK3 release back in 2017

- Might be the thumb drive itself. Have you tried a different one?
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
new thumb drive and formatted.
I'm willing to copy the file onto yet another drive and give it a run.
If the machine is that sensitive to a thumb drive that will be a major problem going forward.

Watch your extruder temps when this happens. It could be the extruder cooled down too much and it had to heat back up. I noticed this happening since the latest FW update. It could very well be that some clueless idiot assumed that the best way to stop stringing was to let the extruders cool down when parked. Wrong again!
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
just wanted an update...
I got sick with FLU last friday and spent the last 5 days in bed. i was not able to run different USBs to see if this help anything.
I'm feeling better, but can't get near the XL for a while.

I got sick with FLU last friday and spent the last 5 days in bed.
My sympathy, there's a lot of it about, I just spent the last few days out of the loop too.
i was not able to run different USBs to see if this help anything.
Also clean the socket contacts - IPA on a cotton bud or a blast of switch cleaner - in case some grease got transferred on a USB stick.
How big are the blobs? Grain of rice? Pea? Dino droppings? A photo might help.
Cheerio,
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
I'm back after dealing with the FLU for the last week.
so frustrating.
this issue has nothing to do with the USB, there is still major bugs in the firmware of the XL in fact the last firmware update bricked my MK3S+ MMU2 machine and i had to revert to get it to work like it is suppose to.
now i'm attempting something new with the XL using this:
i'm going to see if using PET in place of PLA solves the issue as a temp workaround.
to recap:
with the latest firmware and Prusa Slicer. the machine would stop mid print for no reason like the firmware crashed then it would suddenly restart which leaves blobs and causes layer skipping because it looks like the nozzle temperatures drops during this stall out.
each blob is where the machine just sat there doing nothing like it crashed for over 30 seconds. then suddenly it would start up again resulting in that layer skipping because the nozzle was not at the correct temperature. it did this randomly on perimeters or infill or support material. this is not the USB losing connection either.

RE: XL pauses does nothing for over 10 seconds and oozes all over the print
and nope the PETG trick did not work this just happened.
it just froze again for no reason and sat there making a blob for 30 seconds.

Sorry for the slow reply. I haven't encountered this one ... your filament might benefit from drying which *might* reduce the blobbing but after that I'm stumped.
Cheerio,
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
the filament is dry. has zero to do with the filament.
the machine will be printing normally, suddenly it will stop moving over where ever it is, the blue lights will blink on the nozzle led, the lcd will do nothing the machine will act like it has crashed but with no message at all. it will sit there about 30 seconds doing nothing as the nozzle is oozing and it is also cooling off from 210C
suddenly the machine comes back to life like nothing has happened. there is now a blob of filament wiped into the material the nozzle is still cold and suddenly it comes back to life and heats up while the nozzle is making whatever move it was when it decided to crash or lag or whatever it is doing.
as the nozzle is cold it is not flowing material and now it leaves a missing area on the model. so you get a blob and then a part layer skip in that area.
it was not doing this for firmware 4.7, this started after i went to firmware 5.1
i tried to reflash 5.1.2 on the machine and there was no change.
i want to go back to slicer 2.6 and firmware 4.7 and see what that does but i've given up on the machine and don't have time to deal with it. the latest firmware also bricked my MK3S machines. basically prusa is slipping badly into shotty firmware and no proper testing before public release.

Probably not; I noticed the stringing which is usully a symptom and can sometimes accumulate and blob.
the latest firmware also bricked my MK3S machines.
Again, I've not noticed any problems with mine... And I'm still in the learning zone with the XL, I suppose we all are, but I've not seen your problem.
Cheerio,

I've seen the same behavior on my XL befor it comes to the error #17513.
It went to blue but it didn't stop moving only turn blue and cooling down a little bit but stops extruding, then it came back to live and prints again.
After a few seconds it happens again but this time it throws out the error #17513.
In my case it stoped doing that, after i tightened a loose mountig screw on the sandwich board:
Now it randomly throws the error shortly after starting a print, but the other behavior is gone completly.
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
want to add.
when using the XL as a single tool this issue does not occur.
it does not hang and leave blobs and missing layer areas.

RE: XL pauses does nothing for over 10 seconds and oozes all over the print
Is it only this job? Do you have something else you can run that’s a similar size and see if it happens at a specific time/volume/complexity? Almost sounds like some kind of memory cache is being overloaded, like a memory leak or something.

RE: XL pauses does nothing for over 10 seconds and oozes all over the print
I ran a few large single color jobs they run fine. the issue is when using the tool changers then it freaks out and seems to hang, lag, and crash and restart.
Its a firmware problem, the older 4.X firmware did not do this when i ran some tests a few weeks back.
there was a lot of issues with the older firmware which is why i updated to 5.1.0-2
i'm going to wait till new firmware comes out and try again.

RE: XL pauses does nothing for over 10 seconds and oozes all over the print
One thing I see that may be similar is that when a tool is picked up and the dock is not perfectly aligned something weird happens. Sometimes it reboots the machine, sometimes it puts up a weird alert message..
To me it looks as though when the dock is not perfectly aligned when the tool carriage moves in and is stopped, because the pins are not aligned into the lock holes, it stalls the steppers, the fw reads the resulting current increase to the steppers as a crash, but the error handling is incomplete in the fw.
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
in this case the pausing happens seemingly random. if i rerun the same gcode the pauses also is not consistant. showing it isn't the Gcode its something going on in the firmware crashing or hanging at different points.
I've noticed the machine hang for no reason when changing tools.
the gcode wants a tool change and so the XL will park a tool then sit there doing nothing. suddenly it comes back to life and will change tools and start printing with additional tool changes on a torture test, then suddenly while printing it stops and hangs, oozing all over the print.
a few other people have contacted me that have the same issue. not as many people have 5 tool XL machines, and many XL people are also not using the multtool change for prints as often. it could very well be a memory leak in the firmware or a problem with garbage collection where some memory or buffer fills and then takes time to clear. there are also issues with slicer 2.7 over 2.6
basically this last rollout between the new firmware across the product line(mk machines) and the new slicer is causing problems and there is no quick solution.
now its a waiting game from prusa or if somebody figures out the issue and puts out a firmware fix.
right now my MK3S+ with MMU2 works better then the XL and it should not.
the XL roll out from prusa is a disaster on par with the MK3 rollout a few years ago.

RE: XL pauses does nothing for over 10 seconds and oozes all over the print
Yeah… I agree. 😞
RE: XL pauses does nothing for over 10 seconds and oozes all over the print
the sad part is my MK2S machines which i still use and have modified to run certain materials since 2016 still work better then any of my MK3/mini and XL machines.
its sad when the MK2S was the last great product prusa put out and everything since has been downhill.
its sad when the MK3s+ can't make very clear PETG parts because the extruder design still does not work as well as a MK2 design.
and your better off running a color change on a MK2S machine when using a .25 nozzle because the MK3 MMU still can't handle the smaller nozzle size without problems.
basically while i had my MK3 printers chewing out a job last summer i ran this on my MK2 machines. the machines are 7 years old and still work better then anything newer.

What makes it so sad for me and why I post rants about Prusa’s lack of system testing before shipping fully assembled units as well as their not bothering to consider the lessons learned about toolchanging from E3d is that the potential capabilities of this machine exceed practically any other FDM machine ever sold in any of the 3d printing markets! I’ve been unbelievably lucky with mine and it’s amazing, but I see really serious mistakes made which were all self inflicted.
Prusa will not have the luxury of time to fully refine the XL that it had with the MkIII. Bambu will no doubt be looking at snatching the toolchanger market potential away from them and that really really sux.
