RE: Prusa don't honour warranties
It's clear it's a you problem, not a prusa problem.
Seriously, this is just childish. Go offline and do something productive.
RE: Prusa don't honour warranties
I am new to the forum (first post) and have to say i dont like this blog so far. dontbuyprusa, they say you catch more bees with sugar than vinegar or something like that but also I understand your frustration and see this forum is full of extremely unhelpful people. A friend convinced me to get a Prusa and am generally happy with it but I thought fellow members would be more helpful. From what i hear Prusa is a good company so no doubt they will fix you up. I wouldnt go by the interaction with a chat person. they probably dont pay them much so their knowledge isnt that good and its usually a tough job from experience. good luck. hope they look after you - their reputation suggests they would from what i hear. Hopefully people are nicer when I post stuff in future.
You haven't seen what I have.
No, you described it perfectly.
Cheerio,
RE: Prusa don't honour warranties
If you want to be taken seriously (which I assume from your swearing is not your top priority here) you should work on improving the constructiveness of your tone.
You are saying that you get a mintemp error from your hotend thermistor. If that's the issue, then it is not the problem that your Einsy board was fried but simply that thermistor or rather its cables are damaged. In case you didn't stop using the printer after that immediately but continued using it and then fried your board, that is not a warranty case. An official replacement thermistor is 10 EUR or less.

RE: Prusa don't honour warranties
Thank you Therijal. My tone was because I got attacked from the first moment I posted by trolls. I dont give in to trolls. You have to stand up to bullies. You are the first person with constructive advice.
In my chat transcript, you can see that a couple of times I told them that I purchased not one but two additional thermistors. I plugged them both into the hotbed port and both worked. I plugged them both into the hotend port and neither worked. That sounds a lot like the hotend port is faulty to me. Both 5A fuses are unblown.
RE: Prusa don't honour warranties
Starting to think that the port shorted out while still printing. Hotend then heated too far and melted filament more than normal and it then 'blobbed'. Within the sake of somewhere between 10 and 30 minutes ( guess) it was stuck to hotend. Seems like a short time for the amount of mess so very thin filament seems likely. The error was present at that time. I didn't keep using it because you cannot use the printer at all when you get that message.
RE: Prusa don't honour warranties
Maybe. Did you test your original thermistor with a multimeter? Is it shorted? Or are the cables visibly damaged?
If things are getting shorted, fuses will never be a 100% insurance that everything will be alright, on any of the desktop 3d printer boards. Shorting things due to printing complications is certainly not covered by any warranty, that's not a production defect.
I have my Prusa MK3s now for more than 2 years and never had a blob of doom. Bed adhesion is an age old topic of 3d printing. It's a tricky thing and even if you think you have cleaned sufficiently there can be still traces of fat on your built plate, or your 1st layer calibration isn't spot on (anymore) or your build plate has simply fouled over time... I can't be bothered by that anymore and nowadays simply use adhesive every time I print on the smooth bed. The kind that can be very easily removed by a short rinse with water. (Yes, Prusa doesn't recommend rinsing the steel plates with water due to corrosion but I dry them immediately afterwards and don't see the slightest sign of corrosion so far.)
PS: By hotbed port I assume you mean the port for the hotend thermistor, right?

RE:
"Starting to think that the port shorted out while still printing. Hotend then heated too far and melted filament more than normal and it then 'blobbed'. "
That doesn't sound too plausible. As far as I know, if the hotend thermistor shorts, that causes an error and the firmware shuts off the heating immediately and probably pauses/terminates the print, but even if it wouldnt, if the hotend is not heated anymore the nozzle will block even if the gears are still turning and they will merely grind away the filament at the gears and then rotate without much happening.
The printer would stop the heating also in the case of interruption of the thermistor line, so the opposite of a shorting.

RE: Prusa don't honour warranties
Fuse 5A is not used to protect the thermistor input. The thermistor input may be damaged by less current. If the heater switching transistor is permanently opened due to a fault, the current 5A is not exceeded and the fuse does not blow. Such a fault must be resolved by the operator.

Meaning of warranty
A warranty covers defects in workmanship and parts, and assures that the product delivered is as described. You've admitted to allowing a blob to form -- a process that takes hours to accumulate to the point that you e described -- so it's clear you left it unattended for some time. Even then, the blob forming is unlikely to have damaged the board.
If the thermistor had failed during the print, the runaway feature would have stopped the printer.
You very likely shorted the input whilst cleaning. That's the only thing that makes sense to anybody that knows how these printers work.
It sucks, but it's clearly not a defect in workmanship. You can insult everybody here, but you really need to understand that you screwed up or you're just going to do it again with any current FFF 3D printer.
I should also point out that anybody who has dealt with a Creality isn't going to give their support high marks.
Read up on the procedure, learn and move on. Other things will happen, some of which will be painful. Just like any hobby.

RE:
I really hope this guy doesn't manage to blag a new board out of Prusa. Odd because most of the kiwi's I've meet were pretty cool.
BTW I am not an employee of Prusa and I don't have a Prusa printer, mores the pity.
RE: Prusa don't honour warranties
On one hand, I get it. 3D printing can be frustrating at times. I've had similar frustration towards my previous 3D printers. There were times I just wanted to fling them out of the window and curse the world. Had my fair share of blobs, broken components and clogs so bad that one printer eventually needed an entire hotend and extruder replaced. The learning experience can be tough, especially when you have to deal with Chinese 3D printers.
But on the other hand, spamming and abusing people isn't the right way to go about it. This could ironically all have been quickly solved by now if it wasn't done in the manner seen above.
RE:
Contacted via chat and gist of chat went like (paraphrased to shorten exchange):
Me: print started but failed and blob occurred around hot end
Prusa : oh so you damaged the printer when you cleaned it, right?
Me: no. the error appeared before cleaning while blob was attached.
Prusa: You need to watch the print the whole time.
Me: what 24 hours a day? I bought the expensive printer because it is supposed to detect failed prints and stop.
Prusa: if first layer is not right, blob will occur. No sensor can detect that
Me: but I said it printed fine for about half an hour. solidly fixed to printer plate
Me: it is sounding like you are trying to come up with any reason you can find to avoid a warranty claim. Is that what is happening?
Prusa: I havent said that but here is an article that says blobs void the warranty
Me: here is your website that doesnt mention anything about blobs voiding warranty (at the time of product purchase) . It only lists 6 reasons to void the warranty. Getting annoyed and angry with Prusa.
Prusa: sorry you feel that way
Me: You are doing everything you can to get out of a warranty claim.
Prusa: Well even if I could send you a part i wont because it is out of warranty
Me: it wasn't out of warranty when I first emailed. It wasn't out of warranty when you started ignoring those emails.
(Extra information not in chat... warranty expires today anyway. One year since receiving)
Prusa: Nothing I can do. sorry.Me: still trying to get out of it huh?
Me: waiting for response for several minutes....
Me: are you ignoring me now? the claim was lodged whilst under warranty
Prusa: no. It is a mistreatment issue which is not covered by warranty
Me: How did I mistreat it?
Prusa: by not calibrating the printer
Me: The printer is perfectly calibrated
Prusa: printer would fail otherwise
Me: I have evidence otherwise
Prusa: feel free to share
Me: if the bottom part of my print looks fine for half an hours worth or so, and then forms a blob, that shows it started fine and stuck to sheet right?
Prusa: no the sheet could still be dirty
Me: grasping at straws again huh. so now we need to do a chemical analysis of sheet before warranty claims are honoured?
no response for 5 minutes
Prusa: if sheet is dirty, it wont stick. Could even fail after first layers then cause blob
(note, earlier he said the sensor wont work if it sticks. now it looks like sensor doesnt work even if it does)
Me: it isnt dirty. You cant just use that line as a get out of jail free warranty avoidance thing
Prusa: well by our tests there is no way the printer would fail otherwise
Me: poor testing then. Would Josef be happy with the way you are treating customers? All this feed shows is russian-style lies and rubbish
Prusa: not my intention
Me: I am surprised you havent tried other excuses like my humidity is too high in my room
Prusa: your room humidity is not the main reason for failure
Me: i know. The faulty Prusa Einsy board is the main reason
Prusa: from what you shared, the blob is the cause
(actually from what I shared, the failure of the system to detect a faulty print was the cause)
...questioned a few alternative methods just to get printer working
...mentioned that I bought 2 spare thermistors and tried them in both hotend and heatbed ports on Einsy and both worked in heatbed port but neither worked in hotend port so port is faulty (and inspected and swapped both 5A fuses - not blown and no issue with fuses except looks like board shorted without tripping fuse - another failure)
Prusa: did you swap heatbed thermistor? I thought it was hotend.(I assume trying to blame me for damaging the port)
Me: I havent swapped anything. Just tried new thermistors. Currently plugged in normally.
Prusa: could you send me a photo of left side of heatblock
Me: Will you then honour the warranty?
Prusa: of course but cant promise issue is covered under warranty. At least I can help find issue even if the printer was mistreated(ouch. still trying to blame me)
Me: the printer wasnt mistreated. If I plug a new thermistor into hotend port and error doesnt go away, does that sound like left side of hotend or Einsy board
Prusa: Let me mansplain it: the blob damaged the cable which could damage the board. Do you have a spare hotend heater
Me: no but that wont fix the faulty port on the Einsy
Me: We are getting nowhere. Until I can take this further, can you at least give me an einsy at cost price plus free postage.
Prusa: of course, if you would like to change your mind and troubleshoot, let me know.
Prusa: actually, no wait, I cant do that especially if we dont know if board was damaged or not
Me: I previously said "I plugged a spare thermistor into the heatbed port and it worked. I plugged it into the hot-end port and it didnt work." Please speak to technician if you dont understand what that means
Prusa: Sure it is the board then
Me: are you able to compromise on a price( I thought i was being more than reasonable offering to split costs)
Prusa: no. here is the link to buy one
Moral of the story: Prusa charges a premium for features that dont seem to work as designed and also refuse to honour warranties with many many ridiculous accusations.
now cue the trolls in 3...2...1... (I am betting bobstro (aka fake account shledge) will be first)
RE:
The printer failed to detect a failed print. This is a security feature that prompted purchase of this device.
Question: where do you got the information about this feature? AFAIK there is nothing in the MK3S description which states that the printer will detect any failed prints. It should detect temperature errors and stop, and that's what (from your description) happened - its just that was most likely caused by the filament blob destroying the thermistor wires (which then causes the error in temperature reading).

@dontbuyprusa: we generally say: "you did it in slices" when too much is too much.
DISCLAIMER:
I am not and will never be an employee of Prusa Research unless they offer me 100K € gross per year. I have friends who built the printer starting from a wooden frame ... that says a lot.
Has anyone been able to claim anything on Prusa warranty? They refuse to h
onour mine. Faulty Einsy board. They started ignoring emails when I lodged it as warranty (but they were happy to link me to the shop before that).

I dont know what you mean coolio (or at least not sure how that post was meant to be helpful info but that seems to be common on these 'trolling prusa forums' . No help just criticism.)
RE: Prusa don't honour warranties
for a normal user like me to see that there is an update in the forum topic I am interested in means that I could receive useful information regarding the topic it deals with. if you continue to write the same thing in all topics saying that xxxx is not responsible for the guarantee I repeat that: you are doing it in slices.
the help I want to give you is very simple: stop bleating in topics where your problem is of no relevance.

it is difficult to translate from my language to yours "you did it in slices": if I use google translator I get "you cut my penis into slices", maybe it's too slang as a sentence but it should give the idea
