This has happened twice with my K2. The first time I only heard it but just today, I was in front so I could see it happen. I finished a flow calibration print last night which completed successfully and I powered down the printer. I powered it up this morning and it booted fine. The head was parked over the waste chute (the back half of the head being in that pocket at the back of the printer).
When starting a print, the head moved to my right which crashes it into the side of that back recess and makes an extremely loud banging noise and shaking the whole printer. This is before bed calibration or any of the printing actions including raising the bed so it seems like this is an action that the firmware itself is calling for (not the print gcode).
I am on the latest firmware and both times this has happened was on the current latest. It scares the heck out of me each time because it sounds like someone is hitting the printer with a hammer. Has anyone else experienced this? Both times I have canceled the print and rebooted and it seems to work fine after another reboot.
I have encountered the same error twice when the printer was supposed to home before a print. Both times, the lights went out, and the printer displayed the error code XS3000：System error, try restarting.
According to Creality’s support, this is most likely due to loose connections in the motor wiring, and they advised me to disconnect and reconnect them. Personally, I doubt this explanation because the issue only occurs under specific circumstances, and because of the nature of the error code itself: “The connection between the application and Klipper is lost, possibly due to a firmware restart or Klipper service crash.”
By now I’m so used to various printer malfunctions that I’m sometimes ready with the camera to record. In this case, I managed to record the last time this happened.
This is just a minor inconvenience compared to all the other troubles I’ve had with this printer, but that’s a story for another time.
Last night, the printer completely stopped working. It powers on, but it can neither initialize the motors nor detect CFS.
Creality’s email support typically responds no more than once per day, sometimes with irrelevant questions or statements, so I suspect it will take a long time to get it up and running again.
I deeply regret selling my Prusa to buy this unreliable piece of junk.
@Ching Yes this is what mine does…but my lights don’t go off and I think the head moves forward and it pretends nothing happened. I’ve never let it go though so I don’t know what would happen. I just envision those videos of people that take the safeties off a washing machine and throw a brick in…I’m not sure I want to find out lol.
