RE:
you are really funny. 🤣 Your post just amused me a lot. Thank you for it. 🤩 🤣 🤣
not half a dozen for sure ;). And reconnect also solved the problem for me for the time being. It remains to be seen whether it will really go away for those who have the mod. it does indeed take a long time for the error to reappear. Sometimes up to 100+ printing hours. And I don't think anyone has been using the mod for that long
Interesting though that they write that the plug is held too tight and not that it is too loose. This means that the plug mod would have exactly the opposite effect.

You were faster. xD
Thanks!The long-promised FW has finally arrived and the error has also been mentioned.
An apology is also included. I didn't expect that.
I'm not sure, but there half a dozen on the forum so far that this plug mod has completely solved their issue.
The plug being tight is probably the fit between the dwarf case and the plug cover maybe not allowing it to plug in all the way, thus leading to a poor connection.
Not half a dozen..... There's 6 people in this thread on the last 2 pages... And the other thread your posting on had at least 2 that I can think of without even going back to look.
You do realize there are multiple different threads on this and your posting on 2 of them, so the number is probably much more than that
I'm not sure where your skepticism comes from, or if it's intentional, but you appear to enjoy casting doubt and negativity.
I guess do whatever brings you enjoyment, but it doesn't help the situation at all.
Good luck.
RE: Xl extruder stops
So about 20 hours of printing to another fail. this time it didn't dock #2 correctly. Not sure what's to blame. Tomorrow will be spent with a doctors appontment. I'm ready to remove the plugs altogether and just solder and heatshrink the cables. I'm sure it would void the warranty though. This is utterly ridiculous. It seems like a bottomless pit...

Have you greased the dock pins? Prusa recommends you do so. I'd also check to make sure your docks are tight. Try and wiggle your dock. It should not move at all. If it does you need to tighten the screw at the back. I recommend removing the metal mesh plate to get better access. It comes of easy. I'd also recommend some thread locker on the screws.
After this rerun the dock calibration.
I happen to be checking my printer statistics tonight and I have over 2,000 changes on dock 5. It has never missed once. That's the one I usually put support material on hence the reason it has the most changes but all of my other docks have more than 500 changes, again its never missed
I think prusa should offer a fully assembled XL. And I mean fully assembled currently you still have to install the docs yourself even if you buy it fully assembled which I think has led to many problems for people. I'm not saying this is the case with you but being things like tightening the docks being finicky there should be the option to purchase it already completed.
Anyway check that out and let us know. Plus look at the positive side at least it didn't stop extruding.
I've been printing some pretty big prints over the past two weeks each one more than 20 hours and I've not had one failure.
RE: Xl extruder stops
I am wondering a long time about why the pressure sensors of the extruders are not recognizing a problem when the extruder stops. They should sens a lack of pressure with the weight load sensors and stop the print, or do they only sens too high pressure when the nozzle is jammed.
RE:
I think Prusa needs to look into revising the manual to remove the back metal hexagon mesh panel so that you have better access to the screw for each dock. I just did the assembly of my XL over the holidays and used that method after reading the large number of comments on that section in the assembly manual. I really don't know how they expected tightening down that screw through the mesh panel to allow you to get enough torque on the driver to properly seat eacj machined dock piece into the extrusion with the interference fit that they have. I also think it might be worth it for them to suggest you use an actual driver with a handle for that step instead of the allen key they give you.
RE: Xl extruder stops
I imagine that the dwarf connector cover firmly held on the the connector. Then due to vibration, the connector cover would wiggle and pull the connector from the dwarf board. Maybe the cover would get lodged at an angle. So the loose fit between the connector cover and the case was probably still a problem.
RE: Xl extruder stops
well.......the "red screen" with the extruder error in 2.6.0 RC1 works good. xD
But they probably didn't fix anything straight away. Which matches my information.
Well then we wait more and discuss with support. It's so nice to wait. ^^
RE: Xl extruder stops
I haven't had any problems with extruder stops so far, only with 2.6.0 RC1 did I get a red screen for extruder 1. Back to FW 6.1.3 and I have no (visible) problem. Is it possible to turn off the red screen for extruder stops?
RE: Xl extruder stops
About the docking issue. Im not sure if it is relevant but it happen to me a couple of times. It start to print and at some point at a toolchange it actually crashes on the dock. I notice both the times it happen that during that failure there was a layer shift. And if i tried to reprint at the same layer the extruder would crash again. In both the times it happened there more than one items on the bed. If i reslice the same model it just keep happening. What solved it is was printing each item separately. I dont know what the issue was.

RE: Xl extruder stops
I had to file down the dock a bit to get it to seat into the aluminum extrusion slot. I thought I was going to snap that tiny screw with that much torque.

RE: Xl extruder stops
Take all your heads of the docking station. Make sure when you look down at them from the side of the machine they are perfectly in line and straight up and down. If not, remove the ones that are not straight and file down the top and bottom of the block that is supposed to get sucked into the aluminum extrusion slot. They need to sit perfectly straight and in line or there will be issues, ask me how I know.

I have been trying to print the N7 logo for a while now. descriptions as follows:
Top: printed on 6.0.4 FW original dwarf cable connection.
Middle: printed with 6.2.0-RC1 FW with modified dwarf cable connector and cover per this thread.
Bottom: printed with 6.0.4 FW with modified dwarf cable connector and cover per this thread.
Material is PETG fed to my XL from a filament dryer.

I would not recommend filing them. They fit tight, because it was designed that way. They will seat properly when you correctly tighten them.
Filing them could lead to improper alignment as there is only a single screw, which is not enough to locate them. The tight fit with the extrusion provides the location, and the screw is only to hold it in place.

It took three passes of a file on top and bottom to get the 5th one to fit without nurling over the aluminum extrusion it was trying to fit into.
The slot width on the extrusion was varying about 0.015" from narrow to widest.
There was absolutely no way that tiny screw was going to pull that tab into that slot. Just a little bit of filing. It fits great.
To anyone who feels the need to do this, a few strokes of a file and try again.

It's supposed to be tight and the screw pulled them all in fine. You do realize that not everyone has mechanical skills you might have, and what you say is a few strokes of a file is very subjective, and someone could very easily ruin their mount.
So a few light strokes... What did it measure before and after you filed it? What's the tolerance on both the mount and the opening in the channel? What's an acceptable amount of clearance or interference? These are the types of questions that make telling someone to file them a bad idea.
I stand by my recommendation that someone should not follow the recommendation to file the parts.

I ask because your pictures look like underextrusion, not completely stopping. If it was completely stopping you shouldn't see all those strings and damaged plastic
RE: Xl extruder stops
That's right.
I've seen similar results in my prints.In my case, the symptoms have been gradually changing.
When the symptoms first started occurring,
(1) one or two layers, or even a few centimeters high, would be printed normally, and then the gears would suddenly stop for some reason.
(2) Recently, in addition to that pattern, as with the N7 plate posted by @csimian, the amount of filament gradually decreases, goes through a phase of fainting, and finally stops being ejected altogether.
The phenomenon in (1) seemed to occur at the same time as the extruder fan started, so I was able to avoid it by printing with some ASAs where fan stop is recommended, but now the gears have started to stop regardless of the fan starting.
As far as my XLT2 is concerned...
Even if I use the original connector cover
Even if I use a tightly modified connector cover
The gears stop, or they slow down very much and finally stop. .
That's the situation.So far, @cloud1983's prediction has come true (^O^)

Have you replaced the idler door and latch with PCCF parts?
RE: Xl extruder stops
Hi.
Since I purchased the enclosure kit, I have installed all of the PCCF parts that were included.
Those are the idler, swivel, and idler nut.
So the filament is pressed against the gear with the right amount of pressure.
Thank you for checking.
