I seem to be able to set the Silent mode once printing has started, but how can I make this the default and permeant option and prevent it being switched back to Normal again when a new job is started.

I would imagine simply change the default speed in the profiles. If you cut that by 50% then the default speed (100%) should be what the silent mode would be. I think the silent mode cuts speed by 50%…so if you lower the default speed by 50% then you are actually running in “silent mode” even if the printer says “Normal speed”…and if you then push the silent mode, then its cut by 50% again :-). All that theory, havent tried it…but seems logic to me.
Probably not only the speed is reduced to 50% in silent mode, but also the acceleration and possibly the jerk.
This would then have to be taken into account in a separate profile to imitate the silent mode in standard mode.

I came looking for info on when is the “right” time to set print speed mode. It can’t be set before I start printing, and it seems like if I set it while the printer is warming up, it resets it back to normal. So I kind of have to babysit until the warmup and calibration is done. Being able to change the default or assign it in the project would be a great feature.

This Printer has so many amazing features that makes starting a print so simple and a very pleasant user experience.
- You can send the print over remotely
- The AMS will handle selecting and preparing the correct filament for the job
- The printer auto levels the bed and calibrates the extruder flow
- it even reviews the first layer to make sure it’s good before proceeding!
Sadly, as the above user expressed, we still need to babysit the entire start process so that once the print has started, we can lower the speed (side note: and lower the chamber fan speed). I would like to be able to set the print speed as I send the print to the printer so that I can disconnect from the print and move on while it gets started.
This would be a separate enhancement request (which I’ll log later), but I would also like to be able to set a max chamber fan speed percentage which can be over-ridden by the printer if the chamber temp goes up into the danger zone.
Reducing the print speed results in a significantly higher quality print and changes the sound pitch to one that’s not as annoying. So quality/noise are the two main factors here. This is why I mentioned the chamber fan as well, to paint the real-life picture of why we think this would be useful to us.
This printer is nothing short of amazing. Thanks for building such a fantastic product. I hope you’ll enhance soon so that we can set a default print speed and/or be able to decide the speed as you send the job to the printer from Bambu Studio.

100% agree. I could probably work out the percentage of each speed settings prior to slicing but I’m sure there is other settings I need to consider if I want all my prints @ a “Default” speed. If I forget to change to say ludicrous half way through the print, I’m stuffed. It is visible on the layer lines where I have changed the speed. To be able to set the default speed prior to slicing would be amazing!!! Running the print farm would be so much easier.
Thanks in advance Bambu for adding this feature
After reducing everything to 50% manually I noticed that the wiper function is also slowed and not as effective.

One year later and still no update regarding this…
I too opened a petition on Github @ /bambulab/BambuStudio/issues/2923
to get the speeds implement into Studios Slicer, but no reaction yet…
Maybe, if more people like this petition we can get this to be implemented sooner.
Or has anyone found a workaround yet? Just got my P1S 2 weeks ago so I’m pretty new to BambuLabs ecosystem.

If you use Home Assistant, you can link it to your Bambu printer. It could then have an automation that changes the speed whenever it’s printing.
I imagine this is what they automation would look like, but I haven’t tried it since I’m very happy with normal speed. The part I’m not sure about is the speed setting - it may take an enum, not a number.

Is Bambu Lab reading this to adjust the firmware at some point? How can we push the topic?

I agree that it would be very convenient if in the bambu lab application in the Speed section you could simply choose from 4 default speeds (the ones that are built into the printer programmer when the printer is offline)
Great, thanks for the suggestiong!
I’d may rather use the _stage over the _status and set the trigger on printing.

Bringing this back a bit from the dead, I found for some of my prints that the first few layers adhere better (especially with PLA) at regular speed, so I’m using a trigger on layer number:

1st day new user here. So far I’m very happy with the printer, but coming here on the first day of use should be a red alert for Bambu Lab. I too need an option to change the default printing speed to 50% (silent), I don’t mind taking twice the time to print, as long as the printer doesn’t shake everything around it. The 2nd print I made I immediately searched how to lower the speed, and I’m pretty satisfied with 50%, yet I have to set it EVERYTIME I start a print.
C’mon Bambu Lab, adding a default speed option to the firmware should take you what, 5 minutes?
It’s pretty easy to edit a Process profile to use half speeds.
Or put the printer on a more stable platform. I don’t see anything shaking even at Ludicrous speeds, though I can feel a bit of vibration.

Try changing the start gcode under reset machine state starts on line 27 on my X1
M220 S100 is setting it back to 100%
If you say the wiping doesn’t work properly, then maybe add your changes (M220 S50) at the end of the start gcode instead so that it can do all it’s things at 100% and then slow the printing down.

More than 2 years since this thread started, many requests on Github and still nothing…
Although I try my best to always change speeds to low when I need to print slow, its still a huge issue as I forget 3/4 of the times as once I press PRINT - for me its done.
Pressing “PRINT” is the final step!!
All adjustments should be made prior to pressing print.
Can someone from Bambu PLEASE do something about this?
If you’re sending the print from Bambu Studio, you shouldn’t be setting the print speed like that at all. You should be controlling it with Process or Profile for the filaments you’re using. The silent/standard/sport/ludicrous settings are so people printing either from the app or direct on the printer itself can have a tiny bit of control. You have much, MUCH better control of speeds on Bambu Studio, before you ever press the print button.
So you’re saying it’s just for lazy people… did I get that right?
Because yes, me and many others don’t want to tweek with speeds, as speed
is not = speed. There are many settings that correlate and I seriously don’t have the time for that anymore.
Slow gives me quality printing PA
Standard is good for PETG
and Sport/Beyond is fine with PLA.
I (we) want it easy. The buttons are there - just misplaced.
