since changing to a 0.2mm hotend for the first time, the initial calibrating extrusion stage seems to be taking much longer, so much so that the little poop tray gets so full, the filament makes a massive ball!
Is this to be expected?! Seems a little odd. Im slightly wary that the filament ball would eventually surround. the actual hot end
(edit: my latest print did it twice - filled up the tray once, ejected it - then filled it up again before starting to print - then when it started to print nothing stuck to the bed and then just started sticking to the hotend Not a great first experience with this 0.2mm - gonna switch back to 0.4)
I haven’t used my 02mm nozzle yet…but I think this is expected.
Let’s say if it pushes 60mm for a purge on a 04 nozzle takes maybe 20 seconds.
So if you push the same 60mm through a 02 nozzle, I would expect it to be almost 60 seconds.
But this is all a guess, but it makes sense to me…lol
It’s like water through a hose.
Same thing happened to me too… It took like 5-10 min to calibrate the extrusion on the 0.2 nozzle. That’s a Lot. I do understand the what lion7718 is saying, it’s normal to take more time with a smaller nozzle, but still… on the slicer it’s saying like 7 minutes for preparation, but it took like double the time. And I did manually eject the filament from “little poop tray” while it was doing the calibration, it was clogging on the nozzle. Every time I start a print it does that like 10 min of calibration. Next time I’ll measure the precise time it takes to calibrate the extrusion. It would be reassuring to have a response from Bambu on this… Thank You!
I have used the .02 over the last few weeks, and it does take longer…but I just walk away for awhile.
I just don’t think it’s that big of a deal, but i guess that’s just me.
I used the 0.2 nozzle for the first time yesterday and went with Orca slicers default pressure advance values (probably the same as Bambus) and skipped the calibration.
Good Lord… you were not kidding! It was taking so long, I though something was not right!
Also, that little poop chute is not large enough to hold all the extruded filament, and it ends up engulfing the nozzle. Not a fan of this nozzle calibration routine at all.
No update from bambu at this point? This happens all the time on my a1 mini with the .4 nozzle. Whats odd is that before a firmware update it never did this. ANYONE from bambu able to elaborate whats going on?
I am having a similar issue, just picked up an A1 mini with the sale, haven’t changed from the default 0.4mm nozzle, but the printer is producing almost 1cm^3 of extrusion calibration filament. This seems like a lot to be wasting and, while I do plan to try and recycle it, I would like to hear/see a resolution. I am printing models in Bambu Studio on Mac and Bambu Handy on Android, and both seem to be doing this.
I am actually having the same Issue, it poops so much filament before EVERY print that the pooped filament sometimes clocks the nozzle so I have to remove it manually. Is there any way to reduce the poop in the G-Code so that it flushes only like 5mm of filament? I’ve found a solution for the P1P printer, but the G-Code for the a1 mini is way different.
Same here A1 was working fine yesterday. I am using the 0.4 hardened nozzle but I’ve been using that for a month or so (500+ hours) no problem. Suddenly today it’s taking forever to do extrusion calibration
I recently upgraded to 01.03.01.02. So possibly that but it has been fine with that for a few days?
Anyone know when 1.04 is arriving so we can use the auto calibration and whatnot that arrived in studio 1.10?
I have absolutely the same problem and I think that is something wrong with my settings but now I see that everyone have the same problem. I was using just one filament and it was the same problem. So the problem is not with changing the filaments. I’m on A1 Mini with 0.4
Yep, I have the same… A1 Mini, PLA, 0.4 keeps using more and more filament to calibrate? Switched to TPU and the calibration keeps drowning the nozzle and making a mess.
What is the “calibration” actually supposed to be measuring?
I have been experiencing the same issue with all three of my A1 minis. I have to stand there and babysit with a toothpick while it’s purging. If left unchecked, it will clog the nozzle at least 25% of the time.
As I only print one color on each machine (no AMS on my minis), I just turned off the flow calibration on these print and it seems to have alleviated the issue. Not a true fix, but a workaround for now.
Same problem here on A1 Combo.
Could remove the filament poop 3x by hand after wondering about the lengthy preparation.
Then I paused the print on the display and resumed it - seemed to workaround, but not sure if by coincidence or accident.
Yesterday I updated my firmware/software to the most recent one that came out, I think its 01.04.00.00. I instantly started a testprint and it seems like the poop-Problem is solved now! It only poops 2 times for a way shorter amout of time, but I think I will still disable the dynamic flow controll because this seems to eliminate the waiting time for the purge immense.
Not a great first experience with this 0.2mm - gonna switch back to 0.4)
