Toolchanger printing with Tool #+1; cannot replicate error after reloading same .3MF project file. #11611
Comments

I checked g-code output from your project, and there is no T1 command there. I even tried to slice it with "default" extruder selected and still there was no T1 command present in the g-code. Isn't it possible that you used tool remap feature on the printer side? Side note: I strongly suggest to always use the newest PrusaSlicer version available (current stable version is 2.6.1). Note that usually only the current PrusaSlicer versions gets new configuration updates. |

Apologies for the late reply.
I am running firmware 4.7.2 on my printer, as far as I know, there is no
tool remap function in this version of firmware - that I am aware of. And
the issue resolved itself after I deleted the project and restarted the
slicing without me touching the printer, so I am pretty sure it is on
Prusaslicer's end.
I must have attached the wrong files - here is the full toolpath output
summary (some 40Mbs even fully compressed):

and the files chronologically ordered on my machine:

I first noticed this bug a few nights ago, when I loaded up PETG into tool
0 and started a print, woke up to find an empty spool on tool 1. I thought
I had butterfingered something and didn't think much about it. But when I
was starting my print and it grabbed the wrong extruder again, I checked
the settings, noticed the issue, and then tried changing the default
extruder as well as the extruder number and saw the off-by-one error.
I've now upgraded to Prusaslicer 2.7.1 - I will report if I see this error
again. If you don't want to spend time looking at a 2.7.0 bug, I
understand.
Thanks,

Ok - related error - this just happened right now on a print that I am slicing. I am now on PrusaSlicer 2.6.1. Print is a 2 color PLA print. PLA is loaded into tools 0, 2, and 3 (Extruder #1, 3 and 4). The print uses Extruder 1 and 4 only. But as you can see in the screenshot, the holder for the 13mm socket, for some reason, Extruder 2 (PETG) is selected, even though the part is printed from Extruders 1 and 4, and the printer just primed a line on Extruder 2 as well during it's startup sequence. I've attached the output GCode and the project file. Thanks! -=- Terence |

It seems ok if I open your project.

That is wild. On my screen, 13mm(2) shows up as this:
Is there a way to manually force a refresh of the screen? |
|
@ttstam , I see the same state of loaded 3mf as @rtyr . You have saved Extruder 2 for "1". |

Hello! I recorded a video showing what I am seeing. Please see attached. First - switching modes from tool path preview back to 3D now shows me the wrong material loaded for the "1". Thank you. However, I can change and assign other materials just fine - either double clicking or enter and the material takes and the program gives me the option to reslice. I can't seem to change the material for that "1". It does not respond to the extruder assignment change, and the tell tale sign that something is off is the UI shows the extruder remains selected when I click enter / double click out of it, while other tools when I change material upon double click or enter the extruder # is deselected. I believe this is a bug that is not captured in the .3MF output. I bet if I reloaded my .3MF this would go away. I am going to leave my instance of PrusaSlicer running and open until I hear back - maybe there is something you can have me dump out memory states or something to help you with troubleshooting. Anyway, thanks for looking at the problem! Big fan of what you guys do and what you do for the 3D printing community. -=- Terence 2023-11-15.08-03-17.mp4 |

Ok, thanks. I see the problem now. Do you have exact steps to reproduce this issue?
And please, retest it with PS 2.7.0-beta. We changed controls from the PS 2.7.0-alpha |

Unfortunately, no I don't have a way of reproducing the bug either. :-(. |
Description of the bug
I was setting up a print and on watching the printer start the print process I noticed that it selected the next extruder. Tool head #1 (T0) was selected in my slicer, but the printer started the probing process and print with Tool #2 (T1). Upon finding this, I resliced the parts with "Default, Extruder 1 and Extruder 2" selected as the extruder. The results:
Default: T1 (Extruder 2)
Extruder 1: T1 (Extruder 2)
Extruder 2: T2 (Extruder 3)
I saved a copy of the .3MF file, then created a new project and resliced the parts with Extruder 1 selected. This time the code picked T0 as the extruder to probe and print with.
I then re-opened the .3MF file (titled Filament_Routing_with_sensor_Bracket_BugReport.3mf and resliced, and now the slicer behaves correctly and picks the correct tool.
