"Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
Ok, I have had my Prusa Mk3s+ since September 3rd 2022. It has 200 days of print time on it. I have it in a quiet, dry room with 1 door and no windows or fans. I had replaced the entire hot end three times, the super pinda, all the fans, the bed plate, and most of the printed pieces in the extruder. Two blobs of death. Several partial and complete rebuilds. Before you ask, yes, my printer is in fact assembled correctly. Every 6-7 weeks like clockwork, I take my trusty allen wrench and go over every single bolt in the printer to ensure that nothing has worked its way loose. I read the Prusa assembly and maintenace manuals more than I read my bible. And yet, I have been absolutely plagued by a reoccurring issue over the last 3 months. I have been up and down the other forum posts that even remotely resembles my problem. No dice
THE PROBLEM. I start a print. Printer heats up. Hits target temperature. Begins the probing thing, I have it set to 25 points instead of 9. 50% of the time it does not get through the first 5 points. Typically it screams and reads a "Thermal Anomaly" or "Paused Thermal Anomaly" at which point it either A. keeps going (70%) or B. it stops (30%). If it keeps going, it will either set target nozzle temp to zero or not change anything. Immediately after this, 90% of the time it will stop, scream, and give "Some problem encountered, Z-leveling enforced". At which point the print is dead and I will typically enact what I will refer to as "FIGURE 1".
FIGURE 1:
A. Encounter error(s), stopping print, Shut it off, and turn it back on again. Hey you never know.
B. Do Z layer recalibration (this does absolutely nothing, I haven't successfully completed this calibration in months). Printer hits head against far left wall and goes all the way up, grinds a bit (crashes), and then tells me to clean the tip, I do, I then click, and it goes all the way down, and boom, Failure. "something something Try again"
C. Do PID thermal calibration. I do this several times. It has little effect. I set to 230 and it finds itself 5 times and tells me MK3 is OK (it is lying). Running this 2 or more time has a 50% chance of increasing the chance that duing the next "Thermal Anomaly" printer will choose, "A. keeps going" and a 20% chance that it will reduce the odds of seeing "Some problem encountered, Z-leveling enforced" from 90% to 65%. I will typically try to run the print again after this step.
D. Full Thermal recalibration. This takes a bit longer, it is the one that goes 0 to 230 to 0 to 230 a couple times. It finishes up and does not help anything
E. First layer calibration. This is just me grasping at straws, the next thing to do is a complete XYZ recalibration, but I really don't want to do that, so I do this instead, praying that it will do something. It doesn't. In fact, it rarely (5%) gets past the probing stage before erroring out and putting me right back where I started.
F. XYZ recalibration. This is where I get upset. It takes me 40 mins minimum to get my first layer perfect, and running this completely resets everything. Finding a perfectly flat, not-wrinkled piece of paper should not be this hard. As often as I do it, you would think I could figure the paper problem out. However, the printer rarely (10%) has any problem getting through this calibration, and running this has a 35% chance of fixing the issue for approximately 9 days, give or take 2 days. And typically reduces the odds of seeing "Some problem encountered, Z-leveling enforced" by about 15%. I will typically try to run the print again after this step.
G. Out of ideas. Read forum posts and cry
That is my process. 3 months ago, I encountered the problem once in a while, so I ran FIGURE 1, but then my hotend cooked itself, and when I replaced that, the problem went away for a couple weeks. Good prints for a little bit. Then THE PROBLEM returned and I could not print a single thing. I ran FIGURE 1 several times, nothing. So I bought a new superPINDA and that fixed it for a couple weeks. Good prints for a little bit. THE PROBLEM came back, I run FIGURE 1 which does nothing, and I was getting tilted at this point. It had been a minute since I updated the firmware on my printer AND the latest version of PRUSASLICER, so I did BOTH, which fixed the problem, for a couple weeks. Good prints for a little bit. AND NOW THE PROBLEM RETURNS. I have run FIGURE 1 twice and I'm limping it along because I have promised prints to people and deadlines to meet. If the printer somehow manages to get through the 25 probing calibration (by me clicking to ignore all the errors and resetting the nozzle and bed temps because it is setting itself to zero because of the thermal errors), it has a 80% chance of finishing the print, and if it gets through the first 2 layers, that number goes up to 92%. After that, the biggest problems that it faces is warping and bed adhesion due to the fact that my first layer sucks and is CONSTANTLY being reset! >:( I feel like I do not have the time to perfect my first layer before I encounter THE PROBLEM again. So I spitball it and go into a low-quality printing frenzy before THE PROBLEM shuts me down again.
This is getting ridiculous, I'm pretty upset. I just got a new job, and I'm seriously considering a Bambu Labs. I just want a printer that works.

i have been having the same problem for several weeks, have no clue. surprised this post has no response, did you have luck to solve the issue? does Prusa tech support ever read this forum? this is not a new issue there must be already "official" answers to it, but we just cannot find it. can some help us to locate the right link to previous solutions? thanks

I have also been encountering exactly this issue, but unfortunately can't come to any resolution and I haven't found any solutions here.
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
I am also having this issue but with better luck on the PID, full thermal cal, and z level cal. Yet, it still won't successfully print.

Fixed the issue by going back to 3.11 firmware since I don't have an MMU installed!

Wise choice....

If at first you don't succeed, skydiving is not for you.
Find out why this is pinned in the general section!

You can also "fix it" by disabling the thermal model introduced in 3.12. Its never worked great, and if you could live without it before 3.12, you can probably live without it after.

For those reading this in the future: The problem was fixed by replacing the hotend assembly. There was a faulty wire in there that I discovered after combing through it with a multi-meter. Also consider keeping your firmware and slicer on the current version. A very special thanks to an "Ivan" from Prusa who helped me solve this mystery.

I'm having the same problem with termal anomaly, I just swapped a new hotend, rewired everything but had no luck: it does not even complete the termal calibration and starts screaming at 158°. Any idea??
Which was the faulty wire @bernerd-smyth?
Thanks a lot
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
The problem is the new "thermal model" does not work well, and is too picky for the real world. Yes, some people have "fixed" it by replacing parts, but there was nothing wrong with your previous parts so you likely wasted your money. All these years we never had a "thermal model" and the world was fine, so there is no sudden need for it now. Its a solution for a problem that doesn't exist.
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
Update: chatting with prusa assistance they told me that "most probably" my einsy board has to be changed as it "most probably" had a short on a mosfet (in that case, my bad as I scrubbed the nozzle with the metal brush in between prints)
Still I have to check with a multimeter, which I have to borrow.
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
Or you can just send some G-codes to your printer to fix the "thermal abnormality." Your choice.

You mean downgrading the firmware?
RE:
No, you can use the latest firmware, you just need to DEACTIVATE the thermal model feature that was added in 3.12. I've posted a few times on this. You can connect a computer via USB and send a G-code to the printer, you can add it to a gcode in a file or you can add it to start gcode. As long as you send the "save" gcode, it will store it so you only have to do it once. Let me find it and repost.

Check this post.....
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
Thank you very much Allen, I'll read it thoroughly and maybe post there (the prusa assistance told me something about sending the code via cable, which would be dangerous as it overrides a security check, the thermal).
But still, I couldn't complete the PID calibration and the assistance told me that a multimeter will reveal the problem on the board.
Thus, if that's right (I'm gonna borrow the multimeter tonight and test the board), deactivating the thermal model shouldn't work, right?
RE: "Paused Thermal Anomaly" and "Some problem encountered, Z-leveling enforced" wombo combo
I can only address the "thermal abnormality" which appears when you upgrade firmware to 3.12 or beyond. If your printer worked fine in 3.11 but suddenly doesn't work in 3.12, you have two choices. Run firmware 3.11, or run one of the very few ever to be released after that and shut off the new "thermal model" they suddenly felt like adding in 3.12, which can be done with gcode. If your printer never burned up all these years before 3.12 was introduced, it's doubtful it will suddenly burn up when this new feature is deactivated. Do you have hardware problems? I have no idea, but if you didn't have them on firmware 3.11, I doubt the hardware is suddenly bad now.

Also, you don't need to send the gcode via a cable. You can just add it to the start gcode of the slicer.

Hotend thermistor cable. Thin wires from the bottom of the hotend
I'm having the same problem with termal anomaly, I just swapped a new hotend, rewired everything but had no luck: it does not even complete the termal calibration and starts screaming at 158°. Any idea??
