I’m using a p1s and A1, bambu user basically.
in orca slicer (most recent version) , when I do a multi colour print, some times between filament profiles or even colours, the part cooling fan will turn on while purging filament causing crazy jams in the purge shoot. On the same profile and colours, bambu studio does not cause this issue. Any one know what is going on?
Do you mean the fan doesn’t come on in Bamboo Studio.
It is strange that it happens since Bamboo studio is basically the same as Orca. You could try manually setting the cooling fan to OFF and see if that helps.
There should be filament swap gcode, check that and see if there is any gcode causing the fan to kick on. If so just remove that line and try it again.
So here’s the thing @Matthew as well.
In bambu, no issues at all
Using the same profile (not Channing a thing in orca) it turns the fan on while purging filament
I’ve checked the filament gcode and all is at it should be as far as I can see but it ignores my commands and does it anyways…
Is super frustrating and for the life of me I can’t tell why.
The only thing that seems to trigger it is certain colours to certain colours or filament profiles
For example I calibrated spectrum (only diff in filament profiles would be temp, flow ratio, pressure adv and max flow as adjusted in calibration) and going to something as simple as bambu filament, it’ll just freak out on me.
I can’t seem to get a straight answer any where but I’ve seen the issue here and there from my searching around.
Sorry that was long
Hmm, I only have one other thought, are you using different temperatures for the filaments or are they all printing at the same temperature.
If it is trying to go from a material printing at lets say 220 to something printing at 210 then it might kick on the fan in order to bring the temperature down, and that may be what is causing your issues.
That could be it and I thought about it too
Yes spectrum, hatchbox at 215, bambu and most others at 220.
Here’s the thing is it kicks that fan on the entire time (which could make sense cause it’s heating up during purge and fighting to keep it down)
Is there gcode I can adjust? What line am I looking for? I’m pretty noob when it comes to this stuff
Try just printing everything at 220, it should be ok.
The only issue I have with that is I don’t like spectrum at 220 at least from what I’ve tried, maybe I’ll try pulling temps down to 215 since it’s in range for everything else I do. Same concept.
You know much about the gcode fixes I could look at?
I would say just give it a try, you aren’t really looking for print quality at this point but more at trying to diagnose the issue. If the issue stops once you change the temperature then you know that is what is causing it!
That’s fair, I’ll give it a go
Sounds good, let me know how it goes!
Welcome to 3D Printing. I’d like to say it will get better but… 
Lol I’m very familiar with trials and tribulations this one is just puzzling as to what is causing it
I found the last version of Orca to be cranky. It kept resetting my filament settings over and over. Super annoying.
Did you check the cooling settings for the filament?
It can be found on the prepare tab under filament cooling. You should be able to adjust one and save it as a custom then the other.
Ya that much is easy enough to do. But if it’s resetting things, that’s different, I’ll take another look, it might be best for me to write down all my calibrations and start from scratch as well. Re-enter and see if that helps. I got to try a few things from this thread when I get a chance
Ya just didn’t work…
