Reload from disk fail

I used to use reload from disk a lot. But it stopped working. I use it with STEP files from Solidworks 2025, BS 2.2.2.56
It used to not work sometimes. Now it is always.

getting that functionality back would be very useful. Even better is the option for reload all.

Maybe reload selected. reload plate, reload same model (10 copies of the same file), or reload all possible.
I understand how there are some functions that make it so you can’t reload. But knowing what those functions are would be helpful. I would guess coloring a face would make it not work. I want it too. but that would be a complex algorithm. But coloring the whole should be simple.

Looking for any ideas to try. It helps in itterating a design. Are others using it?
The basic concept is right click on the object and select “reload from disk”. it then replaces the current object with the current file by the same name. Keeping the same orientation, location, overall filament…
There are some complications with multi body files. or colorized.

“Reload from disk” still works in Orca…

what might cause it to fail? sometimes it works. It used to be rare that it would fail. now it is rare works. have not found clues when.

Dunno. Wild.ass.guess = gamma.rays

I expect a generational step in slicers is near; Orca Bambu etc are about maxed out. Reload is just one tool that works for a particular workflow and is good for that; I use it often. Downside of course is the single object use.

Another tool is setting .step files to split to objects on import. Not fancy but it improves the experience.

Mainly looking for what are some of the this that cause reload to fail?
Sometime will reload, sometimes complications have unintended results.

Complications I have found:
simplification
splitting to objects or parts
applying colors
different order of objects in STEP.

Things that have worked predictably:
rotating and positioning,
single material.

My problem now is most of the time it is not working.

Perhaps a network error? Copy mount4.step onto c:\ drive and check if you can load/reload from there. All my files live on a remote s:\ drive with no problems.

Do you have a spare computer you can load an earlier slicer version on? btw; describe your slicer.

2.3.1 Orcaslicer reloads stl and obj just fine. No data to share on step.

I have always assumed every time I use this, that all “painted on things” will be annihilated. Seams, supports, color, cuts, etc. Do not expect any of that to survive, only the positioning.

The M is a local drive, not a network. will give it a try from the c: when I get a chance.

the this problem has been a thorn in my side for the past 6 months. So it has been over several versions of BS I am currently on 2.3.0.70
Many different models.
Will try it from my laptop again. Last time I tried it, the results where the same as the desktop.
to give a context, It fails for 80% of the time.
Great points. worth trying.
I prefer the quality of using STEP over STL. Worth using STL if reloading works.
The reason I prefer STEP is when using a STL all the movements of the printer are strait. It simulates curved surface with lots of short strait lines. But step uses some curved lines to the printer. It is higher quality further in the development path. The other part is the file can be loaded in engineering grade programs without loss in quality.

I use fusion .step 99% of the time with no problem. It feels like your hardware doesn’t like the latest Bambu slicer.

Perhaps try Orca.

I receive a response to the ticket with BL.
Reload for step file only works during the same session.
the short description is:
import a STEP file.
save the 3mf file.
close BS.
open BS and open the 3mf
try to reload the STEP.

my testing is it does not reload. part of my process is design, print, close program, do other stuff, refine, repeat… Unrealistic to leave BS open. Effectivly making the reload not work. It does work for STL files.
Can someone please confirm that a step file does not survive a close of BS.

Bambu Labs says it is a known bug and will be fixed in a future update of BS. Currently non fixed on 2.3.1.51.

not really a solution but a closure for now.

Not solved in 2.4.0.70. (adding support for H2C)
not reloading a STEP file after a closing BS and reopening.

Me too … I also use SW2025 and send models as Step files. And also in v2.4.0.70

I wish STEP worked. It is a benefit that the model is not faceted like you find with STL.
STLs are either very big because of so many facets or practically useless because of too few. There are exceptions with geometric parts.

It does? It’s all I ever load into Bambu Studio.

Where are you storing your STEP file? It can’t be moved or renamed after loading into Bambu Studio and path needs to be accessible to Bambu Studio.

I can’t replicate your issue. I “reload” step files daily without issue and new instances of Bambu Studio.

read the prior posts.
reloading STEP files works as long as you don’t close BS. It is a known problem with BS.
what I am describing is:
Inport a STEP.
Save 3mf file
close BS
open 3mf
try to reload STEP file. Does not work.
It does work if you don’t close BS. It works fully if you use STL.

I was able to replicate the reload failure.

If this is an issue, suggest using Orca as the same reload process doesn’t seem to fail.
