When I came back to a print that had 3 minutes to go, I found the following messages…
The accelerometer data is unavailable. The communication connection to the tool head maybe broken, or the accelerometer may be damaged.[0300 0f00 0001 0001 1648 19]
First layer inspection terminated due to abnormal Lidar data…
Despite these messages, the print was successful (Standard Mode)
I opened the print head cover, pressed all the cable connections my finger could reach.
I haven’t seen these messages again and I’m still printing.
Of note, the print prior to the one associated with these messages was done in Ludicrous Mode, took up most of the bed and had at least 6 step losses (hot end moves to front right corner for a couple of seconds).
Each recovery was on target and the print turned out fine.
Any ideas what that was about?
Could something have been shaken loose?
Is something bad lurking under the hood???
Could print quality be affected even thought the messages haven’t reappeared? I have noticed some underextrusion and first layer issues since these messages appeared but it may be simple paranoia.
@Stu, is it solved? I´ve got an identical alert, yet in my case, I have the part cooling fan, i.e. the Front Housing Assembly fan failure. I ordered a USB-C cable and a Front Housing Assembly and filled out a trouble ticket.
From what I’ve seen, the USB cable is still the easy thing to handle. And luckily it was only the USB cable’s connector that caused the accelerometer error to me.
But after seeing what could happen, I prayed to heaven a few times that nothing would ever happen. If in the next generation is only the quick nozzle change applied, then… I have to take more print jobs away from the X1. If it runs great, but beware of having to pick up a screwdriver…
The third intensive relationship with my Bambulab printer - I usually just throw away the printing heads with exdruder and quickly screw in a new one… with all the advances on the X1C, this is really a huge loss in quality compared to other 2 year old printers and other current printers. The X1c is a good printer, but that’s just… what the heck… just twist it and sewn it up and solves the problem
In my case, it was the Front Housing Assembly, specifically the fan.
I´ve stored the faulty one, as I intend to understand the cause of stopping to work.
The only damage I ever had with fans was the bearings, so for me, this is new.
I also share your opinion regarding the reliability of some components; up to now, the supposed consumables have proved to last longer than foreseen. Yet, I had some minor issues with electronics, e.g., faulty cables, that were rather than expected despite being simple to identify and solve.
Anyway, I am satisfied as I can quickly identify the cause and ensure the component is available at a fair price. But I can imagine the frustration that would be if I needed to spend weeks looking for a cause and solution.
