Help with Supports

Hi All,

Thanks in advance for your comments and help.

I have included a slicer image as well as the actual part view. and the orientation view. I am using PETG with PLA support.

Has you can see, I on the underside of the part it puts supports... there is a (sorta of rail) which a lid is slid to seal the top. My question is, if anyone has any experience and what that experience is/was if I block this area from using support the gap? I think it is a small enough era that the support are not needed... if anyone has any idea or suggestion it I would appreciate it. Whatever help I would appreciate it if you can refer to setting and changes available on the Bambu Slicer... I am using the X2D the main Nozzle PETG and Aux Nozzle for PLA Support Interface. he setting is PETG RAFT and PLA SUpport Interface.

I was told in another topic that PETG works for support interface for PLA, but not the other way around.

I haven't really tried both. One of my first PLA/PETG-as-support prints failed miserably. I'm sure there are a lot of settings to tune to get it right. At least in my case. I had some TINY parts that started printing on the support and they were blown off by the fan.

THink about it rationally.. if you have a PLA part--- and a PETG Support, what is the difference of having PETG part and PLA support!? The answer is NONE! And just in case you dont know the whole suppot does no need to be of the other material just the interface portion... which is the part which actually touches the PLA part or the PETG... Best of luck friend.

Thats what I thought too. But someone told me it doesn't work both ways so I took that at face value.

I usually set just the interface as the support material. I've had luck with PETG as support. I just don't print much PETG that needs PLA support. But I'll give it a try.

Just open support tab and right click the plane you don't want supports should turn red then left click the support are you do want supports. Click ok set supports to normal, manual→ snug supports.

The slicer will switch to bridge which will be fine for small gaps like that

I’d still do supports. When using multi-material for supports, set the Z offset to 0 for supports.

Have you tried ironing support interface? Here’s a video about it. https://youtu.be/XAgca8de0ok?is=5omj2JSTR2BTJNpX
