Has anyone else noticed them time estimate from Repetier to be wildly inaccurate?

Has anyone else noticed them time estimate from Repetier to be wildly inaccurate? Depending on my infill densitys if I use honeycomb it can be anywhere from 20 to 200% off. Last night I started a “6 hour” Print at 7 PM at 7 AM it was still at 50 minutes to go…

Yes, I’ve found the estimates to vary widely. I had someone tell me it had to deal with the theoretical speed versus actual. So the SW may have the values such as max speed or infill, but it doesn’t account for getting up to speed like when changing direction or the time to get to the max speed.

Yea, Based on how it changes based on my infill density and what type of infill there is I am certain that time calculation is built with the bot traveling at 100% velocity, 100% of the time and acceleration values are not built in. Linux CNC is like this as well and both of them have modifiers that you can tune to get the time estimates a little more accurate. I was just curious about others experience with this. Frustrating at best haha

Curator is the same way

I find that if I multiply by 2, it is more or less correct. Can’t repetier measure hor long time it takes the printer to execute an instruction and compare that to its own estimate and adjust?

odd, on my Rostock max, I’ve found the estimates to be pretty much spot on… Even with Delta aceleration, it seems to be pretty good.

@Jesper_Krog_Poulsen I apply the same rule!
