Time estimates from PrusaSlicer
-
Is minimum layer time coming into effect? Do you have any macros or anything that set a different speed/accel/jerk than in config.g?
Have you tried running a print simulation on one of these files? How accurate is it?
-
@Phaedrux
Nah nothing that slows it down at all, the settings i posted over is my printing/normal operating speeds etc. I only slow stuff down when probing/homing, and i've checked that the above mentioned parameters is applied when printing(in the object model browser). I'll run a simulation on the files later and see what it spews out.You agree that i've input the machine limits correctly right? (sanity check
😂) -
I only had time to simulate one file yesterday, the "Estimated: 1h27m / Realtime: 1h55m" one. And the simulation said 1h31m, so closer to estimation than reality (heating time is about 5min from 22c to 110c, so it's not the reason either).
Edit:
Simulated anoter file with and Estimate of 3h39m / realtime 4h20-something, the simulation said 3h45m.On a little sidenote, is it a way i can stop the simulation from spamming
Error: Attempting to extrude with no tool selected.about 2times every minute thru the whole simulation? -
@Exerqtor add
T0 P0to the start gcode of your files, or to the end of config.g to get rid of that error. -
@oliof Yeah i found the "issue" i have the first extruder set via a global variable in my start macro, but it that apparently don't work in simulations.
-
So the time estimate from the slicer matches fairly close to the actual simulated time, but the actual print time is much longer?
At this point I'd say share all your system files and macros so we can take a close look at what is happening.
-
That's what i saw too, i was surprised the simulation being that close to the estimate ngl.
Well this is going to be a longass post with all the system files, but here we go:

But like i said, i checked the object modell during last print, and all the values seemed correct

It'll take me some time to go through that.
Do you happen to use input shaping? Pressure advance?

It's alot
🤢
Yeah input shaping gets defined in config.gM593 P"zvd" F49.3Pressure advance get set in filament config.g

Just simulated AND printed another file, estimated 1h7m, simulated 1h32m, printed 1h31m (with preheated bed and hotend).
I'm lost...
Another one:
Estimated 0h21m, simulated 0h26m, printed 0h31m. -
@Exerqtor did you see my earlier post? User n8bot has made modifications to PS to make the estimates more accurate for RRF. Part of this is a facility to fetch the maximum speeds and accelerations from RRF. https://github.com/n8bot/PrusaSlicer/releases

Yeah i did
😅:@dc42 said in Time estimates from PrusaSlicer:
@Exerqtor try the PrusaSlicer fork from n8bot. It can fetch the Duet machine parameters to compute more accurate estimates.
He's fork haven't been updated in ages either (even older than SuperSlicer), so not to keen on jumping on an even more buggy build lol. But i saw the pull request on the master branch he made and commented on it yesterday so maybe something happes.

Can you send the speed, accel, jerk, etc commands while a print is in progress to see if the values are what you'd expect them to be?

Sorry for the slow reply, but covid paid a visit so i haven't had the energy to deal with this lol.
But i just managed to check the numbers during print, and apparently the printing accelerations are at 500 for some reason.
So i need to track down what the f**k sends that
