Hi guys,
I had to change the hotend piece, as it got clogged. I inadvertently moved the black sensor next to it. When trying to calibrate, it bumped into the bed and indented a dot. I tried to get the sensor right and after reboot, it seemed to work correctly.
However, when it finished the job, it was not centered vertically, but rather on the side - see pictures attached.
What did I do wrong / how to fix? I hope I didn’t screw it up too bad …
Do you have a link to the model?
It’s hard to tell, but it looks like that model might not have a good contact with the print bed. You didn’t mention a raft or brim. I’m thinking maybe some pieces came loose, but enough stayed attached that it printed poorly? Most of the tail segment pieces look fine, and really only the head looks a bit weird.
Thank you clewis. The adhesion is fine - I printed the vase at 25% and it was fine. But going larger, it feels like something is off as the tip goes up on the z axis…almost as if the vertical linear modules are not aligned?
This is the Eiffel Tower and the F117 Nighthawk
Here’s another view of what I was trying to print - I did not have this issue before changing the tip, and I recalibrated twice
It looks like you are having layer shifts, which means that there is an issue with your Linear Modules. Check to make sure that you have all of the cables routed exactly as defined in the instruction manual, that all of the cables are very snug, and that nothing is even slightly loose. If that doesn’t fix your issues, you will need to contact Support.
The flexible build surface looks like it is new, so I am guessing that you haven’t had the machine very long, correct?
As an addition to @CNC-Maker’s post, also try reseating all of your cables. If you think it has to do with the z-axis being out of alignment you can try tramming them (search the forum for how to), but I’m not convinced this is the issue. It looks like the layers are consistently shifting in the y-direction, is this correct?
Hi all, so the issue was that I pulled out the black sensor from the 3d printing head too much. I tucked it in and it worked. Snapmaker also suggested the following, but when I checked, this was Ok for me. For sure, if you take the 3d printing head down, be sure to turn off and restart the printer. It is probably doing some extra checks and that’s how you can avoid trouble.

The issue is caused by the Y-axis linear modules.
Here are the steps for your reference:
Dismantle the heated bed, platform from the Y axes so that we can see the movement of sliders.
Power off the machine, push the sliders to the foremost end of the linear modules, and make sure they are at the same level. Place the laser work platform across the two sliders, making sure they are on the same level.
Here is a video for your reference:

Then power on the machine and click “Home” on the touchscreen. Please check if the sliders remain at the same level as the laser platform.
And then you can control the sliders via the touchscreen. Make the two sliders 200 mm lower and check if they remain at the same level as the laser work platform.
After that, swap one of the Y-axis linear modules with the X-axis one. Then run the same test.
Choose those two that have the closest moving distance as the Y-axis.
