I have a baffling issue with one of my S1 Max machines. I recently had a print failure where the print lifted off the bed and the print head collided with it hard enough to tear a chunk off the heat sock. The next time I tried to print I got a clogging error before any material was extruded, which isn't out of the ordinary. So I swapped to a fresh nozzle and tried again. The same thing happened. The printer heated up, attempted to purge, then gave the error. I tried having it resume and it then attempted to start printing until it realized that it wasn't extruding and threw the clogging error again. When I remove the nozzle, I can see that filament has made its way into the nozzle and at least started to melt as it can not be easily removed.

Since then, I have tried:

• Multiple nozzles
• Replacing the heat sock with a new one
• Different types of filament (ABS, ASA, PLA)
• Removing the PTFE tube, heating the nozzle, and running a poke tool through the extruder to clear any obstructions
• Removing the nozzle and sliding the poke tool all the way through
• I confirmed that the nozzle is getting up to temperature

Nothing seems to have any effect. My next step is to try replacing the extruder. Is there anything else I should check? Maybe a bad temperature sensor somewhere allowing the nozzle to overheat? I'm frustrated as I have a major project deadline in a few weeks and can't afford to be down a printer. Any suggestions would be greatly appreciated. I have created a ticket with AC, but haven't gotten a response yet.

I had a new issue yesterday. It happened on the very first layer of the print, so the only thing lost was time. I started a print with AI detection on, auto filament change on, and a spare spool in the ACE. There was very little filament left on the first spool and I probably should have just tossed it, but the auto filament change has been seamless so I thought nothing of it. I started the print and went to bed.

This time, the filament ran out half way through the first layer but the printer never detected that the filament was out and did not auto change. Instead, it continued to "print" with no filament. I awoke to a print complete message and a single layer of a print.

I'm not too worried about the auto switching but the printer failing to detect the filament running out is a little disheartening. Anyone else seeing this and how often would you say it happens? I would hate for this to happen near the end of a multi-day print.

How much filament should be left in the nozzle after a successful print? I just removed the nozzle after a print finished without a clog and after the filament retracted there was still about 2 mm of filament sticking out of the throat of the nozzle. Is this normal?

Is anyone else have issues printing with ABS in their S1 Max? I am new to FDM printing so I am probably doing something wrong. The printer prints PLA flawlessly and has been chugging along for almost 200 hours without as much as a hiccup, with the exception of the two times I tried to print with ABS.

The first time I tried printing with ABS I just decided to wing it. I used Anycubic ABS fresh out of the package. I used the .4MM nozzle and the default settings for Anycubic abs in the slicer (nozzle 260c, hotbed 100c). The printer warmed up, went through its usual calibration routine, then immediately reported a clog attempting the initial purge of filament. I checked and it was indeed clogged pretty badly. I tried a cold pull and that did not do the trick. I ended up having to heat the nozzle to max and use a needle to clear it.

The second time I tried printing ABS the results were much the same. Still using Anycubic ABS and a .4mm nozzle. The filament had been stored in a sealed container with desiccant. I increased the nozzle temp to 280c and left the other settings the same. Just like last time, it clogged on the initial purge. Only a tiny stream came out of the nozzle then it reported a clog.

Does anyone have any thoughts or suggestions? Anyone experiencing similar issues? Is Anycubic ABS just crappy? Any help would be greatly appreciated.

My day 1 preorder of the S1 Max combo finally arrived today, with a twist. Fedex delivered while I was not at home. I came home to not one giant box, but two! It appears Anycubic logistics made a mistake and shipped me two printers. Unfortunately I am too honest to keep the second one so I contacted support. I'm sure they will ask for it back, but one can hope :D Curious if anyone else has heard of someone receiving multiple printers.
