Failed print after 15 hours

[Fatalrage]

Hello All,

I have completed a number of upgrades on my P1P lately and so I am trying to determine what could have caused this failed print.

Upgrades: Stainless Steel nozzle 0.4, Motherboard fan, X1 Cable chain/P1S Toolhead cable, Arc Enclosure, AMS

I have just performed maintenance on it after the upgrades, belt tensioned, cleaned Carbon Rods and lube on the Z Screws.

I am trying to print this AWS Riser from here - BLV - AMS Riser for X1C / P1P / P1S V3.1 Final by benlevi - MakerWorld

I am using the designers 3mf and printing plate 1 and using their slicer settings.

At about 6 hours in my eSun Black PLA+ roll run out and the AMS loaded in a 2nd roll automatically, you might see a difference in the Matte to Shiny lower in the print because of that.

Because of the new enclosure, I printing this in PLA with the front door open and no top on.

At about 1.5 hours to go on the print I came to check on it, and you can see the issues I am having, I had to stop the print.

EDIT: I have noticed that the ducted heating had turned on around this time, and its a small room, and it made it quite warm in this room, not sure if that is a contributing factor, just trying to think what was different from the 1st 15 hours.

Looks like a nozzle clog. Have you tried performing a cold pull or swapping in another nozzle?

It looked like due the the heating coming on in this room it got too hot and then it led to heat creep in the nozzle and started a clog.

When I went to extrude I could hear clicking in the hotend, meaning it was having trouble pushing filament through the nozzle. I struggled to find a pin small enough to insert all the way into the nozzle but I was able to get it to flow properly again.

I am now slicing the model where it started to failed and hopefully I can stitch these together without it looking like a mess, and hopefully save an 18 hour print.

Thanks all!

Get a quantity of ethyl acetate and some syringes from Amazon, say. That is a solvent for most pla’s. You can solvent weld easy enough, if the edges match good enough. You can also dissolve pla, and make a filler. You only need a few drops of the solvent, but a half litre is cheap enough.
