1143 hours here. Many failed prints - but mainly my own CAD abilities!
3000+ hours on my X1C in 16 months. Itās been a relatively painless experience. In terms of repairs so far:
-AMS lid split where the lifting knob is located about 2 weeks ago.
- Camera needed to be replaced at probably 2000 hours due to incredible low res being transmitted
- Micro lidar sensor has become nearly useless as itās always telling me its dirty even after cleaning. They sent me a replacement under warranty but havenāt gotten around to replacing yet.
- I had one massive blob form on the nozzle while printing overnight once that was so bad I bad to replce the print head front cover.
Besides those few smaller issues, itās been running quite well. I wouldnāt be able to run my business without it.
Iāve been printing almost non-stop since I got the X1C 52 days ago, Iāve got 864 hours so far. I replaced the cutter once, and used the grease that came with it to lube the Z-axis screws. Other than that it has been working flawlessly.

Wowā¦ I didnāt think I had been using it that muchā¦ Got it for Christmas and it shows 1177 hours.
That is a lot of lightsabers and sea life decorationsā¦

3500h changed maybe 2 nozzles. And one engineering plate and one extruder. Original belt and rest. This of course with carefully maintenance and lubrication.
I have 6 x1cās and so far, with the exception of some new nozzles they are doing their jobs. One failed lidar but I donāt even bother replacing it. Itās just not adding any value for me.
Printed hundreds of hours of abs. Switched to pla now to save on cleaning everything.

Thanks for the report!
Sounds like you would be a good cannidate to test the new ObsidianX Hiflow nozzles from E3D for longevity. I have one and it does increase flows by 20%-40% but im not sure how long it will last
Hello, Iām new to the forum, this is my first post, I found this a very interesting and useful topic. It helps me estimate cents/hour to allocate for machine maintenance when costing a print. I got my X1C about 2 months ago and right out of the box I had the carbon rod binding issue that Iāve seen discussed online. I could print PLA and PETG but as soon as I went to higher temp filaments it would fail after a few layers, spewing material into free space. Customer service was very responsive, they sent me a gcode to run and then determined it was the carbon rods. They sent a replacement (a royal pain to replace, took me 6 hours) but since then it has run like a charm. 200 hours, running mostly ABS, PETG and PLA but also a little PA and PC. Also carbon filled PETG and PLA. I have had a couple of failed prints when the PETG didnāt stick, switched from the engineering plate to the PEI plate fixed that. I had one extruder jam from a softer filament, swapped out the extruder and was able to fix the jammed one so I have it as a spare. VERY happy with my X1Cā¦ side note, you can fix the carbon rod assembly that is sticking, I will look for that topic in the forums and post how to do that.

FYI I posted info on fixing the carbon rods on this chat: āThe resonance frequency of the X axis is lowā
3D newb here, just got my X1C w AMS 3 weeks ago, only 175 hours on it. So far so good
