I have 2 X1Es and on one of them the extruder fan seems to die relatively quickly. After one print it makes that awful humming noise and will last for a few hundred hours. Im on fan #3 and the printer is only at 500hrs of print time. Any ideas why the printer would be killing the extruder fans? it dosent spin freely when the fan dies and feels like a bearing is going out. Any Ideas? The other printer has been a champ and is around 1500hrs without an issue.
Heated chamber? 25ā¦ 25ā¦ 25ā¦
Too warm? 26ā¦26ā¦26ā¦
English pleaseš what are you two talking about?
I am guessing here, but I think they are suggesting that the chamber temp has been too high and is effecting the internal electronics in a bad way.
No idea why they are counting upā¦ 27ā¦27ā¦27ā¦ (?)
maybe but considering I print pretty much the same file on both printers it doesnāt explain why one printer has the fan fail and the other hasnāt had an issue. I did notice the old fan was rated for .3A and the new one I ordered was rated for .4A so well see if it makes a difference I guess
Apologies. The 25ā¦ stuff was just me getting to the 25 character minimum.
What I was asking was if the printer was running with a high chamber temperature since that can shorten the life of fans that are running in that. Sometimes with multiple printers, people will configure different printers different ways where maybe one is running with a fairly hot chamber and the other is doing low temp stuff. So was just asking in case it was something like that.
Or they could just be inexpensive fans with occasional lemons.
After awhile you see the same names in every thread you go to. You eventually āget to knowā names as best you can and sometimes goofy stuff comes from it.
I knew MZip was trying to hit the min character count by counting. I did too, but counted one higher. Essentially agreeing.
Figured everyone would just ignore itā¦guess not.
Recently we have been struggling with extruded fans failing on our X1E units. Seems like itās a common problem because quickly the spare fans were sold out through most distributors through the end of 2024. I made an adapter cable to use the X1C fan on our E, but quickly had the same problem of fans failing in 10-20 hrs. Since we always print ABS, I suspect it was a heat issue with the bearings. I purchased some Ampec MR52-ZZC Mini Ball Bearing Ceramic Si3N4 Balls 2x5x2.5 bearings and instead of replacing the whole fan, just replaced the bearing. The ceramic bearings are designed to take the heat. Hopefully this works, to extend fan life to a reasonable amount of time. I will report back in a few weeks on bearing life.
I think it is better to use brake cleaner to clean out existing oil then apply a generous amount of silicone spray to the bearing. Oil dries out quickly with heat but silicone after dry would still provide lubricant to the bearing. After all, silicone spray is just grounded silicone + WD40 combined.
I use silicone spray all the time to replace thick oil from ball-bearing that coming from china.
I will have to give this a go instead of discarding and replacing. I disassembled one bearing and the amount of metal inside of this tiny bearing was pretty impressive. It felt crunchy, probably no hope for that one. But maybe I will try on a newer set and see if I can get more life out of them.
Of the 10 bearings purchased from Ampec, they were ā ā ā ā . Didnāt last any longer than the stock fan bearings, and some them were worse being failures right out of the package.
I have since ordered from AliExpress some full ceramic bearings. Expecting them in a few weeks. I will post back if they hold up. Just want something reliable.
If anyone else has any suggestions for extending bearing life with the extruder fan, let me know. I did find that the best thing to extend life so far is a āHotend fan duct for X1C & X1ā model by Maoirae. This about doubled the life of a hot end fan.
In my case, the electronic of the fan died before the bearing gave up. So, I just had to replace the fan
