Anyone recently tried to print PLA with PETG as Support Interface?

[user_819771961]

I have used Bambu’s wiki to manually adjust the settings as well as using the test profile to no avail. I tried to just print the support interface but despite 0 distance it causes a lot of stringing with clogging up the nozzel.

I think tried to print the whole support as PETG using Bambu’s test model settings from that wiki and that’s even worse.

Anyone had good luck with printing PLA and PETG as support interface yet ? Ironically I published models for those scenarios on the X1C and they work brilliantly on P1S and X1C - just not H2D …

I have tried the other way. IE: PLA as support for PETG.
As long as the supports were on the build plate, everything worked fine. However, when supports were needed on the PETG part itself, it was a no-go.

It is probably an ID-10-T error, but I gave up after many fails!

Maybe related to this problem which the community is still trying to get a grip on.

Printing trash now please help

I was printing fine and was looking at something on Marker and clicked download into Bambu Slicer and it changed some settings and now when I print with supports it changes parts of the print to supports or prints hollow. These printed fine before. Pictures show the same piece printed before and after. The before one I can try to break and it very solid. Now just peels apart at a touch.

Yea I notice especially when there is just a thin line required.

Here blue is petg and it’s just a no go. I wonder if I can use a modifier to disable the PETG interface for these thin parts and just keep it PLA.

But yea. So far the reason I bought this thing just doesn’t justify the cost.

You can download 2 profiles at bambu for h2d for both support types. works great.

I print often with PETG as support material for PLA, no problem so far every print came out perfect. I use a shortcut, I select “Support for PLA” as interface layer so the settings get auto-adjusted (z height, interface pattern etc) then swap to PETG for interface layer.

On my X1C, PETG for PLA, yes. PLA for PETG, not so much. PETG printing requires higher temperatures. The PLA tends to jam the extruder because of it. But ultimately, I stopped doing this. I make a lot of functional parts. Unless the purge volumes are VERY high (like in the 1200+ range), some amount of support material remains and contaminates the print, severely weakening the layer-to-layer adhesion and making the prints weak and easy to break.

For a H2D owner, though, it ought to work just fine (provided your H2D works just fine).

I say in my first post that I literally did that.

Oh clever. Might try that. I do wonder if my interface layer in that area is just too thin. Or the material in general.
