Suddenly the z axis has started failing, the bed is not touching the nozzle. I run self calibration and it touches the nozzle and completes the calibration, but when i go to print the bed doesn’t touch the nozzle. I have tried everything even to removing the bed to look for loose connections and filament bits and then run another calibration and that works but when trying to print something, it fails to touch the nozzle and i get the z homing error message.
Error message on screen: Z axis homing failed; the task has been stopped [0300-4000 171016]
Anyone else had this issue? Ticket logged.
In the meantime, chat gpt provided me with a useful link to a youtube video about adjusting the z axis via the bambulab studio 3d printer gcode - and i followed it and my printer is printing. The code is set z height at -0.04, so i changed it to 0.03 and it now touches the nozzle. here is the video: https://youtu.be/_0awJsJu-e8?si=QsIDszCUReGzAtM9
im havving thhhe same issue, yesterday i print a couple files fine, then on the third it starts to show the “z axixs stuck” message, i checked everything on the qrcode step by step, it all seems fine, but i still have the issue, the tip of the nozzle dont touch the bed, if i try mannualy on the screen it toouchs, but when i do the homming, it doesnt
I have to admit, I’m a bit puzzled by what you’re asking. I’ve already given you all the answers, but it doesn’t seem like you’re making any effort to engage with them.
The second link I gave you included instructions on how to look up an HMS error code. Did you follow them? No—you just posted the incomplete error code here. This shows a lack of effort on your part. Was your expectation that we’d read the Wiki page for you?
Alright then. Let’s go to the link and read the Wiki page for you… just for fun.
If you had searched the Wiki page for the code that you failed to include in your first post, you would have found this:
Which, if you’d actually read my first response where I had to guess what you were experiencing, turns out to be the exact remedy to that error code.
Also worth pointing out—if you had just pasted the error code that took us two rounds to extract from you into either the Wiki or the search bar on this forum, you would have found the answer in the first three results.
Here’s a bit of advice: Asking a question with incomplete data is human. Giving incomplete data a second time after being asked politely is inconsiderate. But doing it a third time—when the answer was already in the first post—is just lazy. That’s not going to win you any friends here, and it’s not going to make people want to help you.
Replying personally to Olias, I found your advice unhelpful and your egotistical demeanour quite irritating. But I now resolved my issue which was something so simple as replacing the hotend with a new hot end and the bed levelling is now working. I even spoke to bambu support who were quite helpful with that checks I should make but were not required.
Upon closer inspection I figured that there may have been some mechanical or thermal inconsistency that isn’t obvious during calibration but shows up during printing—like:
• Slight nozzle clog or damage affecting back pressure and flow rate.
• Heat creep or poor thermal transfer in the old hotend, causing inconsistent extrusion.
• Bent or worn nozzle affecting the actual Z height once heated and under pressure.
• Or even slight play or wobble in the heat break or nozzle threads throwing off the distance during printing.
Since replacing the hot end my z-axis issue is now resolved.
I didn’t even take Olias’s useless advice I’m old school with 3D printing and hands on and that has certainly paid off
