it seems an error post-processing scripts added please clear this scripts and try again

[ARSoderberg]

lanewei120 No, that is not the cause. I have never added any post-processing scripts. I re-checked my submitted test .3mf file and there is no post project script. I have also checked other projects that get this error, and they too do not have any post-processing scripts (no orange circle arrow).

@ARSoderberg ok so where is the printer profile "Cooper Medium Production 0.4 nozzle" from? could you show you detailed steps to reproduce it? including create this printer profile

from your 3mf, the post-processing scripts was wrongly set to invalid value

[ARSoderberg]

lanewei120 I stand corrected.

Ok, when comparing process file 'Cooper Medium Production 22@P1P.json' and a few other process profiles compared to those that come built-in, I find the following in the 'post_process' field in the one listed and some other of my .json files.

"post_process": [ "", "Notes - Smooth plate\n", "25 Top-Left Medium\n", "25 Standard Medium" ],

Note that the text of this field does not show in BambuStudio, that editable field is empty. and in my Beta 3 of BambuStudio 1.9.0.70 the red highlighted circle arrow (from your screenshot does not appear for me when using the processs profiles that have the issue.

Upon removing that field and it's data, follow up testing shows that the error 127 does not occur.

The bug in this case seems to be the empty first line in the post_process field above, it suppresses the display of the text that follows. Whe the "", is removed. The 3 lines of notes do render in the Post-Processing scripts field inside BambuStudio. I have no clue how this content of this field came about.

Thanks for helping me track down my pain in the neck.

So it seems that this Error 127 'bug' is not one, and this can be closed.

as we can not reproduce it , we can not find why this post-process scripts was changed close this issue currently and keep on watching if can reproduce again, we will dig into it
