So something I’ve run into many times on models where there are slicer generated outcomes like modifiers and exposed infill, are users tend to think they’re smarter than the defaults and just outright refuse to even try the 3MF, but rather get an STL or just throw out the settings and then complain (and rate) based on these assumptions.
I’ve written up some impromptu instructions for Bambu studio to help these users on Reddit and in comments on MW, it’s rough, and should probably be accompanied by images or maybe even a video… thoughts on this list of steps?
Delete any copy of the 3MF file you have to ensure you have a fresh copy.
Before opening the file do some rudimentary prep: Open up Bambu studio, click new project, and ensure that your printer model is selected in the upper left corner, and your build plate matches below. If you’re using an AMS, click the detect filament button (little ams icon with swirls) and it should update to the filament you have, or if no AMS, you can manually select the filament.
At this point close Bambu studio, say no to saving, open it up again, and if you receive a dialog asking about updating or discarding settings, click DISCARD.
Now go to maker world and click open in Bambu studio, before clicking preview- see if the printer choice is correct, it will likely be wrong since it populates the printer type the file was made with, so select your printer mdoel and nozzle size from the System Presets, - this is important - when the dialog pops up with two columns - click “Use Modified Value”. If you don’t get this dialog, purposely change the printer to a wrong one and back to the right one - do use modified value each time.
Now click preview - you should see the intended output.
Seems quite reasonable. But I will point out the reasons why I often challenge the provided settings. I have struggled a lot with bed adhesion issues. They plagued me when I had an Ender 5 and it drove me away from using it. Recently (a few weeks ago) I purchased a BL A1 and have been having a blast. I had no adhesion issues for about a week, then the troubles started. So I used old techniques I knew plus looked at the forums for new ideas. I love it when a designer assures me that I don’t need to change this or I don’t need to change that because it’ll all be good. Then I print it and I have edge warping or parts breaking free. Then it’s back to glues and brims and all sorts of other techniques. I view the offered profile as a starting place. Sometimes they are well thought out and can be done as-is. But often I find it worth the trouble of doing some minor mods to reduce the waste of time and filament on a failed print. That said, it is different for brand new users who really don’t have enough experience to jump in and make changes without at least trying the offered settings. And not all designers are well experienced as well, so sometimes the profiles might not be as good for all situations as they might suggest.
Agreed 1,000%. Never said otherwise. Things are inconsistent for me. Sometimes I can do 3 or 4 prints before needing to clean. Sometimes it seems like I need to clean every time. It get’s very annoying. I recently purchased additional plates, so that should make it less annoying as I can clean all my plates and then do several prints before doing a big round of cleaning.
I clean my (gold textured PEI) plates thorougly with hot water and a good quality dish soap every thirty or so prints. In between each print I wipe them off with a microfiber towel and 99.9% Isopropyl. You can’t use a lesser concentration, as the water content will not mix with the oils of your fingers on the plate and will just smear them around. 60, 70 or 91%, all of which are the concentrations you’ll usually find in the usual retail stores, will not work. It MUST be 99.9%.
Using the above method I’ve never had a print fail due to adhesion issues. Not a single one, even with more demanding materials like ASA etc.
100% same and never had adhesion issues. Cleaning your plate between prints isn’t annoying it’s part of the process, skipping it is asking for problems.
So I just want to bump this up becuase though this use-case may be niche (deliberately set custom infill) the issue of users opening up the 3MF as geometry only or an STL, or even opening the 3MF properly but changing settings or switching profiles and DISCARDing settings that were in the 3MF is a constant one I am running up against with users. I’ve copy and pasted this screenshot 12 times in the last week alone. Now this is a prison of my own making, yes, but I do wonder how many others are experiencing low star ratings or other complaints because users INSIST they are using our 3MF files as-is when they really aren’t. The fact that I’ve had 100% success so far (as of 9/30, waiting for a few users to respond) with pasting these instructions tells me users are both unconcerned with keepign settings and unfamiilar with HOW to keep our 3MF settings and will accidentally discard them while believing their using them correctly.
