The printer started to print basic models weird and I discovered that the Z-axis has some issues. How can I fix it?
I have contacted Bambu Lab Support to ask them for help, but they have not responded yet.
Most of the global end users have already contacted us. We appreciate everyone’s support and cooperation, and we remind A1 users who haven’t contacted us yet to do so as soon as possible, either directly or through official resellers, so we can assist you with the next steps promptly.
@Neiljt I have other problem, not the cable one.
The printer cannot work without the Z-axis!

I don’t own the A1, so I’m speaking out of school, but for many 3D printers it’s normal for one end of the z-axis to be left unconstrained, and it would likely create binding problems if it were constrained. Your video does look pretty loosey-goosey though.
I would like to help you more but,
Please cease using the A1 before replacing the heatbed. Switch off, unplug, and securely store the A1 in a safe place.
you really shouldnt be using the printer , so im gonna suggest you use customer support AI or customer support live chat in bambu handy
This printer has the Z-axis not working properly. All the printed models have waves, and I’m pretty sure they should not be there.
To help with this… I checked my A1 and it also has a similar flex on both rods when I push on them via the gantry. The flex in mine is buffered by some spring/cushion. To note, my A1 prints fine. It’s hard to tell how much flex you are having from the video. Are they completely loose and bang around in there?
One is very stiff, but you can flex if you press very hard, and the other one is loose and it moves freely.
From this gif you cannot tell the gravity of the issue. Bambulab forum don’t support video, only photo and gif.
6 days have passed and BambuLab Support have not responded to my ticket. Does anyone else have this issue ?
@BrotherC can you help me with this issue ?
Check the coupling on the bottom of the Z axis it maybe loose and allowed that screw to slip down. Should be an easy repair. Looking at mine that screw looks to short so that’s what make me think it has slipped down.

thanks for the help, will check it up.
had about the same problem - in fact “just” badly filled the hole at the top.
printed two bushings from tpu https d.pr/f/4juF83
both on the shaft and on the screw - and live without problems from now on

@danechka THANKS for your help. I will print the two bushings and upgrade the shaft and screw.
You should add them in makerworld.com
I’m sure there are many interested in this bushings for A1 3D Printer.
It’s a very simple stl - I made it in tinkercad in a couple of minutes. and I’m not sure it’s a regular problem, rather than an accident of “underpouring” of fixing glue.
It’s simple, but not everyone has the knowledge to make them.
This is an improvement in the long term, and is better to add them as soon as possible so that the printer don’t start having problems in the future as we had.
As simple as you think this is, many will find it useful.
ok
