RE: Extruder stops mid-print
Print them with the other extruder! I'll be running another 5 color print tonight for testing.

Make that "Monkey Brain Creations"

After replacing two buddy boards, I was still seeing the issue happening. I was watching "Monkey Brains Designs" video with all of his issues and saw the one that he fixed his XL by reprinting the cable connector. I then found that mod and installed them.
It's an ongoing process.
RE: Extruder stops mid-print
Download the file and give it a test, your faulty extruders might just start working again.
i'm having the same problem, i cant even rely on any of the 5 tool changes as the problem occurs aleatory, on mine it normally stops after the first layer, but i had some cases that on multi colour, one or more extruders don't even work, making a spaghetti mess.
on those last two months, has been just a waist of money trying to print with this printer, i'm unfortunately relying on two kobra 3, not the same quality prints, but enough to have the parts done for my home business.
RE: Extruder stops mid-print
I got the files, it’s printing right now in black ABS on my QIDI X-MAX3 due heat chamber to avoid it to warp.
Thanks for the help.
RE: Extruder stops mid-print
My third multi color print finished without any issues and looks perfect. unfortunately I’m at work and can’t upload a photo. I’ll do some more testing over the weekend. The issue might be resolved!
RE: Extruder stops mid-print
Second and Third Test prints with the new connectors and cover.
RE:
Printed out the modified connectors. THANK YOU JIM!! This fixed the problem and all prints since modification have been flawless. I printed out the parts in Prusament PETG (Orange...I was out of black). I used the M3x16 Torx head cap screws that I had left over from the XL build instead of set screws as designed. I'm quite pleased. Thank you again, I will post the pictures to the printables site to get the designer due credit.

I’m glad to have helped! Spread the word!

RE: Extruder stops mid-print
So just to get this right: You need to print some new parts on your own for a 3-5k Euro printer just to get it working? Seems very strange to me.

Snark does not contribute to the conversation. If you have nothing constructive to add, don't post.

This is the whole point and spirit of open design and contributes to keeping the printer price so low.
... but having written that I haven't encountered this problem so I don't need the fix.
Cheerio,
RE: Extruder stops mid-print
Wasn't ment to snark. Just to verify if I got this right, because it sounded unbelievable. You have to use a third party solution for a common problem that prusa wasn't able to fix on their own.

Not exactly common, there are many thousand XLs in the wild but only a few dozen users reporting the problem; most users, including me, have never seen it. It's quite likely that Prusa never saw it in testing. It appears that two parts have to be on the edge of specification for it to occur, but bucause parts are made in batches when it does happen a (small?) batch of affected nextruders are produced.
If, as seems likely, this is a fix then as more users report the success to Prusa's github they will be able to remedy it in the production line and add this, or a variant, to the repair schedules.
RE:
I still buy Toyota even after they had a connector problem on a brand new vehicle, it was discovered through customer use and ultimately fixed by Toyota. I'm quite sure Prusa is eager to find and fix problems so that they can produce an even better product moving forward. Open source/coop mindsets are different than mainstream. I very much apprecciate it, but it is not for everybody. I'm sure the populous of people that buy Bamboo Labs, Creality, or other canned 3D Printer solutions have all experienced issues with their machines. It's an iterative process, and Prusa has a wonderful community that is willing to share experiences and offer helpful solutions. If this thing really offends you, there are a host of other printers that might be a better fit. I just bought my Prusa XL, going into it with my eyes wide open, and have worked through the hiccups with help from this community. I would very much go down this path again.
RE:
To be fair, we don't know how many XL printers are out there and how many of these are in trouble. The fact that only a limited number of users are reporting problems tell us very little because, in all likelihood, only a small percentaje of XL owners are registered in this forum.
After following these forums for almost four years, I don't like at all the overall picture I see since the announcement/release of the XL and MK4 series. I'm not talking about people posting here, but about Prusa behavior as a company.
only a small percentaje of XL owners are registered in this forum.
But as most people won't even look for a forum unless they have a problem to fix we can safely assume a far higher proportion of those arriving do have issues.
Cheerio,
RE: Extruder stops mid-print
It doesn't offend me at all. I am a great fan of open source and community solutions, but it still doesn't make a very good impression that someone else came up with a solution before the manufacturer. And I still go with the common problem; like it was pointed out, it is only a small percentage of users that is registered here. And reading about this problem several times here, tells me that it is not a single incident. I might be biased since my brand new factory assembled XL printer is not working and support wasn't able to fix the problem; in the end the only solution they had was to send it back for factory repair. Tells my something about quality control too. And yes, I have other printers here, that cost a fraction of the price and work just out of the box.

RE: Extruder stops mid-print
I have received my warranty part and will install it few days.
Before the new board installation it would be actually intresting to know if connector holder would fix the problem.
This is getting quite off topic,but i reckon that only 5% of prusa printer users "know what they are doing" and quite often are open minded with technology and capable of solving (electrical, hardware) problems. It is much easier for this kind of person to analyse the possible problem sources, list for probability and try to have the error fixed themselves rather than going to customer service loop, beacuse it is necessary for the person to get it back up asap.
1% or less of these people take the trouble of letting other users know of possible fix.
3printers have evolved really fast and the 1% issues remain, this is the normal process of development.
Maybe not a h od example,but look at cars, every 4-5 years they take only a small step forward in technology. What really changes is just the visuals in interior and exterior. Ohh boy and if you only knew how much anomalies are happening khmh..ford..khmh
