I used my x1c for months with flawless results and thought this thing is great. Then I started having the occasional random areas of the first layer not sticking. Kept getting worse until I could not print. Tried different spools (all dry), different materials, cleaning the print plate, different print plates, took AMS out of the equation and cleaned lidar - all didn’t help. Did a full calibration and was able to get a print to stick. Then it started again. The areas that do not stick are not consistent locations. One print, the line calibration didn’t stick at all which I would think should throw an error?
Messaged tech support stating the above and said I think it is not reading the bed height properly. Received a canned response that wasn’t going to help the problem. As it asked me to try the things I had tried or change print settings. The print setting had not changed. Or increase the brim. If its not sticking, making it bigger is not going to help!
I responded that I was disappointing in the canned response and sent other pic of the 1st layer not sticking on half a circle. I explained that on my old printer this would be a bed leveling issue and I could problem solve but this machine is too complicated. They suggested it was the filament and i should try official filament. Ugh!
I did a full factory reset and back to as good as new. I messaged back saying - thanks for nothing and asked why this would have fixed my issue. "we suspect that the issue may be related to the bed leveling data, "
Many many prints and a month later and it started again. Full reset and fixed. So I messaged - Perhaps I have bad ROM? Or where is the bed leveling data storage? Is there a quicker way to reset the bed leveling data? and or confirm that is the problem? (and jokinly) Any chance I can trade my machine for a H2D? Their last response is that they want to send me a new bed. Not sure how to respond as I am pretty sure this will not fix my problem. If the bed is bad why would a full reset fix the problem? Is the software stored in the bed?
So Im asking for insight here. Also the line calibration, what good is it if it can’t distinguish the lines being completely missing? I have also recently stopped doing the bed leveling as i didn’t fix anything and seems more writing to the RAM might be worse.
I’ve had the exact same issue for the past month. I’m thinking the recent update may has done something weird to the bed leveling.
Same as you, I’ve tried using different filaments, cleaning the plate many times etc. Printed perfectly for over a year and seems to have craped out around Easter 2025.
I’m tried downgrading firmware 01.08.05.00 but it just seemed to bricc the interface and it because unresponsive.
I’m now resetting to factory settings and will try again.
Any luck with a solution? I have been encountering this issue in the past 2-3 days. First layers seem to fail consistently after replacing the hot end and washing the build plate.
So I inquired with tech support as to why a new bed would fix my problem if the factory reset fixed my problem? Their response is to manually level the bed and if the problem persist, upload the print log so that they can assess the flatness of the heated bed.
Again I don’t understand as I thought the system measured the location of the bed and would compensate? And if it is not level/flat why would a software reset fix the problem? Since the bad area were not consistent location, wouldn’t that prove the print logs had the bed as not flat even though it probably is flat?
I had been using the auto line calibration if that’s what silver118822 is referring to by Auto calibration. But I stopped using it before it failed the 2nd time.
The (temporary) solution was the factory reset. But who knows how long it’ll last? Done at least 30 prints in the last week with no problem so far.
Possibly your initial bed level is marginal, your printing conditions change slightly with ambient temperature or bed temperature, the automatic levelling can no longer provide enough compensation and you have problems. When you restore factory settings the calibration collects new levelling data, correcting the problem for a while, until conditions change again.
I don’t know what printer you had before, but the initial levelling (tramming) of the X1C is not difficult. Just follow the Wiki instructions. I do recommend this wrench for the knobs to make precise adjustments easier.
