I made a long print recently, which was supposed to last 4 days and 10 hours. I started it on thursday around 10am and it was supposed to end monday around 8pm. On friday I noticed it was not estimated to be done around 1pm on tuesday. Each day the estimated end of print was delayed by a few hours. At the end, it was completed on tuesday at 4pm. So it took 20 more hours than the initial estimate, about 20% more time than initialy estimated by bambu studio (v2.0.3).
I’ve then started another print which was suppose to take 7h49m and was supposed to complete tonight at 00.15am but it’s now estimated for 00.59am and I guess by then it will be 10 to 15 minutes more.
Has anyone noticed such a behavior with the H2D being this late compared to bambu studio’s estimates ? I was more used to see my printers print faster than the estimates.
I am quite used to that on my X1 for multicolor prints. Filament change times use a fixed estimate. However, PTFE path length, purge volumes and the occasional retract repeat all affect the accuracy of this estimate.

The PTFE tubes that came with the ams2 pro are very long. I’ve been meaning to shorten mine. I think that does add quite a bit as previously mentioned.

Having the same issue on X1C and it’s on a multi-color print, however, all of the changes are done and the bulk of the print was remaining in a single color.
Estimated time to complete from the start was 2 days. After a full day (all the color changes were complete) the time moved from 9:30am finish to 10:00am finish. I didn’t think much about it, but in the remaining 1/2 day, the time has moved from 10:00am to noon and now is estimated to finish just after 1:00pm.
So currently there are about 7.75 hours remaining (estimated)… curious why it’s drawing the print and the estimate out without any color swaps for the whole second day. At this point, it looks like my 48 hour print is really about 52+ hours.
Isn’t there an option in the slicer to re-calibrate based on measured print time, or am I thinking of resin? (I just leave it running and come back when it summons me).
