RE: My XL is now called Sir Clog-a-lot after upgrades. Any ideas?
So, drilling out the plastic in the clogged tips works fine. I started a print today and guess what? Same crap. It mostly clogs during the first or second layer, but it does seem to clog in the same region regardless of what layer it's on. Once the head gets into the rear, right hand, quadrant of the print bed, that's when it starts. So I'm wondering if it's a broken wire of connector issue like you said earlier now. Once the head bends the wires in the direction, it stops pushing filament. I'll try to mess with it some more. Dang frustrating. I circled the area where it normally clogs in red. The more I think about it, the more it seems to almost always happen in this region.
The head does have the little hooded cover over the connector that is supposed to stabilize the connector, or so I thought.
I wonder if maybe the filament gets stuck in that corner in the tube, or the connector loses connection like you suspect. I personally don't clip the ptfe filament tube on the clip closest to the extruder because I think it's forcing the filament to run a path it doesn't naturally want to
Also try printing up this connector and see if it fixes it. This connector makes sure the plug doesn't wiggle. Also make sure the screw on the plug cover is not too tight.

I'll unclip the tube like you said. I unplugged the connector, spun the connector, and plugged it back in. Maybe some torque will keep it from disconnecting. I'm really leaning towards that is the issue. If it does it again, I'll print the hosing you posted and try that. I made spool holders with bearings so the filament should feed super smooth. The only drag in the system now is the ball where the filament sensor is right after the spools. I had it out of the system for a while but put it back since the bearings make it feed so easy.

Well, apparently I can't just copy and paste the URL. Forum fail.

Well, it's on layer 4 now and in that same zone and not missing a beat. Must be the connector. I'll print the new back-shell/latch/holder thingy tomorrow when this is done. Crazy it's something so dang simple as a wiggling connector. I wrapped the wire harness around the front of the strain relief thingy.

Yup. Failboat. Came in only to find it crapped out after I left. Printing the new connector holder parts now. This is getting so dayum old.

Printed the new connector backshell parts and installed them. Purposely printed some brackets in the zones that were causing the most trouble. Ran end to end. I finally have some faith it's fixed.
SURE APPRECIATE ALL THE COMMENTS AND HELP!!!!!!!!

Glad I'm not the only one loosing my head over seemingly unexplained failed prints. I recently had one head that started consistently failing to extrude mid-print while all the other continued. Coincidently it was right around the time this post started.
I did at least a dozen cold/atomic pulls, and tried a "Purge filament". I cleaned every groove in the extruder after many failed prints, I tried switching nozzles around, switching filaments, increasing temps, 50% speed all to no avail. Always the same head that would fail to extrude for the whole print. I more or less settled on printing 4-color prints until last week when ANOTHER head started the same thing.
Currently printing the previously mentioned extruder parts in PC-CF to see if I can save my sanity (...I mean save my printer from my sanity).
FWIW, My printer was a 5-head Day 1 pre-order, and I have been using the enXLosure since it was posted. I recently also put covers over the grill behind the extruders (because it sits up against a cold Canadian window).
Based on what I see here, having an enclosure is definitely a defining factor for this issue.

It sure is quite frustrating to lose a print mid steam especially when the prints are 12+ hours long, over and over and over and over ..... and over again. ESD filament is almost $100 a roll and I've sure wasted my share of it. Try the new connector backshell and stabilizer mentioned above. It "seems" to have fixed mine. I'm heating up for a 12+ hour print now so we will see if it finishes or not.
I get that its cool to 3D print the printer parts and that all the parts are open-source and all that jazz. However, most of the time that fixes on these things wouldn't need to be fixed if the original printer parts were injection modeled with good material from the get-go. It's a narrow, razor's edge, but some of these parts are nothing shy of sketchy from the start. I've even contemplated having our machine shop machine some of them out of aluminum so they will last until I retire.
Have a great Monday, all!

Well....failed over night after 9 hrs of printing (3 shy of finishing a part) and failed this morning on layer 1. I give the hell up. I guess I'll start the pain staking process of dealing with tech support that 19 times zones away at some point. Don't know what else to do.

Emailing info@prusa now to get a parts kit or whatever they can offer. Thank you for following up with that info!

Message back from Prusa says theres a firmware fix that "should" fix most of the XL extrusion errors and sense the ones that it doesn't. Gonna load it wed when I get to work and try that.
