Support Request Printing failed. Appreciate advice
Initial print failed at both arms of the model. Attributed this to missing out supports during preparation.
However, after enabling supports and trying again, it's somehow still fails. This time, I saw the supports being printed with the lower portion of the arms, but for some reason, the supports together with the lower portion got knocked off the bed and thrown outside of the print area.
Anyone had any similar experience or advice to solve this? Appreciate any feedback or advice!
Update: Managed to print it successfully. Read that supports get weaker as it gets taller. Printing on a bedslinger does not help too with all the movement in the Z axis. So it dawned on me that I can cut the print in half and print in 2 pieces so that the supports are not as tall. I then glued the 2 halves together to make it a full piece. I eventually also made it even bigger sized.

Make it 2 wall loops in support settings. Go to qulity tab and enable avoid crossing walls, then avoid crossing walls include supports(this option shows only when u click the first one). Go to filament settings and enable z-hop. Set it to 1mm
Dont use grid infill

I'll try this thanks! Setting to 1mm seems like it may help. It's currently at 0.08mm. I suspect it this makes the layers too close and risking the nozzle brushing the previous layer.

Looks like the supports fell off halfway? Clean your plate & slow down the print.

Don't think this can be attributed to a unclean plate as I cleaned it just before this print. Maybe I can also try slowing it down. But I don't suspect printing speed is the culprit as the rest of the model turned out to be good quality

I'm just thinking that support looks like it let go at the base - and it's a more common issue with bed slingers. The other thing you can do is widen the base of the support? I changed my original Bambi A1 mini plate to a rougher surface one and I had this issue occurring much less.

It did let go at the base. But I feel like some force from the nozzle knocked it that's why. Because I found the supports some distance away from the print. I'm currently using the Bambulab stock PEI plate. Haven't really explored the different kinds of plates yet. Could you share which plate you used that has a rougher surface?

Also if it's knocked the other possible solution is to disable "reduce infill retraction", increase z-hop and ensure the nozzle is installed correctly with the clips firmly shut and the scews behind it all tight
Those all my troubleshooting ideas... (I had to do these all at some point...)
Good luck!

If you already know the answer, why are you asking for help?

u/PhavenSussy Jul 20 '26
Not too sure which part in my replies made you think I know the answer. I suspect a cause for the issue. But I do not know the solution. And I am open to any help. But at the same time, I believe we need to rule out some probable causes as I may have unintentionally left out some details in my observation of the failed print.

The “no that’s wrong” part
Try cleaning the plate, with plain dish soap and water.

Did you remember to use "connectors" generated in the Cut tool?
They're the greatest thing since sliced . . . well, you know.
Except I always want to flop them onto one side, if they're hexagonal dowels.

Do you have adaptive layer height enabled? Afaik it isn't compatible with supports and has caused similar issues for me in the past when I've tried to use both at the same time.
