prusacontrol time estimates almost always too short? MK3
got my MK3 yesterday, have ran 7 prints so far, didn't really pay attention to the first 5, but the last 2 prints, estimate at 4:22 and 0:38 respectively, but ended up taking 6:30+ and 0:45, which is 49% and 18% longer than estimate. the forum is not allowing me to upload .stl, .prusa, or .gcode files or I would share them for review
anyone else experience this? any fixes?
Re: prusacontrol time estimates almost always too short? MK3
Try a new (alpha) version of Slic3r here: https://github.com/prusa3d/Slic3r/releases/tag/version_1.39.1-alpha
It has implemented FW simulator, so the estimated time is very very accurate (<5% error) 😉
Re: prusacontrol time estimates almost always too short? MK3
I have not used the slic3r yet, just the prusacontrol. on my latest print the estimate was 39 minutes, the actual time was 1:03. so actual print took 61% longer than estimate. file was https://www.thingiverse.com/thing:2758405 . settings were Prusa PLA, 0.2mm, 20% infill, no support, no brim
Re: prusacontrol time estimates almost always too short? MK3
next print
estimate 0:43
actual 1:19
83% extra time
Re: prusacontrol time estimates almost always too short? MK3
OK, I try slice it in Slic3r alpha
There is a GCODE:
Try it again, and you will see 😉
Re: prusacontrol time estimates almost always too short? MK3
I did switch to slicer prusa edition and found it much better. although it would not slice a lithophane I did. I was able to slice it in prusaControl and just reporting the result
estimate 3:31
actual 5:14
48% incorrect
Re: prusacontrol time estimates almost always too short? MK3
how can you see the time estimate in slic3r?
Re: prusacontrol time estimates almost always too short? MK3
You have to slice it in the latest alpha version from GitHub, then export GCODE and after that you will see these numbers. 😉
Re: prusacontrol time estimates almost always too short? MK3
ah, great, thank you, that worked.
I did everything except for exporting before.
Re: prusacontrol time estimates almost always too short? MK3
You are welcome. 😎
The new estimated time is very precise. I have tried it for 5 prints in total and max. error was 3% at very long prints (a few hours).
Re: prusacontrol time estimates almost always too short? MK3
I too would like to see better estimates from Prusa Control software. I do use Slic3r & Cura, but sometimes I do use Prusa Control, and I wish it was a little more precise on the time estimates.
Re: prusacontrol time estimates almost always too short? MK3
The PrusaControl uses the Slic3r as a backend, so it will benefit the new accurate Slic3r time estimate once we release an update of the PrusaControl.
Re: prusacontrol time estimates almost always too short? MK3
I still haven't seen a print where the time estimates were close to the real print time. For me errors have been always close to the 60-80%.
I'm currently printing a part where prusa control estimates 2h and slic3r (1.39.1 alpha) 2h45. It has passed 2h30 and it still is at 65%, printing in normal mode...
I guess it still needs a lot of work.
