I’m experimenting with speed, using the Bambu Studio software.
I’m printing the benchy and I’m currently at 34 minutes for a print. I’m using the EasyPrint PLA. I want to experiment and try different settings and see if I can increase the speed. But so far I can’t.
What I’ve tried:
I’ve increased Max volumetric speed to 100.
All speeds in the speed tab are 10 000 mm/s. Slow printing down for better layer cooling is off.
I’ve changed minimum Layer time to 0.
Still 34 minutes. What setting am I missing? Inner wall takes 3m47s according to slicing result. Doesn’t matter if I put 400 mm/s, 500 mm/s or 400 000 mm/s, it’s still 3m47s.
I just want to be able to test and experiment. Are there any hidden limits that’s not shown or am I missing a setting?
Are you using the new high flow nozzle. If so make sure you have that selected in the filament profile(Direct Drive High Flow) and the print profile when adjusting parameters. Also when you are in the speed settings make sure you have the correct nozzle selected (left/right)
I’m using a standard 0.4 nozzle. What do you mean nozzle selection in the speed settings? I also can’t see a nozzle selection in the filament profile.
Is there a maximum speed for a given nozzle? Like if I want to print faster than 34 minutes I need a bigger nozzle? I remember though that I printed a benchy in around 23 minutes when I got the machine.
hello JeHa620
motogp11991 doesn’t understand that you are simulate it with “infinite value” and don’t obtain it inside result, and cannot have less than 34min, whatever you do
I’d suggest to look closely at speed, flow and layer time in the preview. That may give some indications.
Also, the fan speed control in the filament settings is driven by calculated layer time while also being used to control the speed. Since it is only documented in the wiki, it is not an obvious speed affecting setting.
Sorry I was assuming you were printing with a H2D. In print profiles for the H2D and filament profiles for the H2D Speed settings have a drop down menu for Standard nozzles and High Flow nozzles. By default when you click on speed settings everything is for standard nozzles. If you make any changes to speed it will have no effect at all if you machine has high flow nozzles installed. You would have to select high flow at the top and then all the settings change in that menu and for high flow nozzles only.
As @NUsul mentioned I didn’t realize you were printing the Benchy that came pre-installed with the machine. That is a 3mF file and you cant change anything for that file. You would have to download a benchy from makerworld if you want to make changes.
I tried downloading the original Benchy, but it also came as a .3mf file. I managed to get the total print time down to 27m55s though, with the model printing time at 21m44s. Maybe that’s near some kind of limit?
Or should it be possible to reduce it to something like 10 minutes? I’ve set all speeds to 10,000 mm/s and the minimum layer time to 0. However, when I check the Speed tab in the Slicing Results menu, it shows an average speed of around 2,000 mm/s. Shouldn’t it be much faster than 21m44s if the average is really that high?
By the way, I’m not actually trying to print at 2,000 mm/s or anything like that, I know that’s impossible. I just want the freedom to tweak all the settings and run some tests.
For example, the inner wall still takes 3m44s to print, regardless of whether I set the speed to 400 mm/s or 10,000 mm/s.
