  • I hear you. I am 100% an advocate for better street design.

    What I’m trying to tell you that it’s more complicated than you’re making it out to be. Especially in this specific instance. And yes, it may have been made to sheer off but that doesn’t really change they were going I believe 70+ in a resedential area. There are muni tracks in the middle of the road which makes it quite wide and it’s a big long curve.

    Honestly and truly I believe the driver must have had a momentary old person ‘black out’ just slammed on the gas and was essentially unconscious. We’ll never truly know. Putting up a concrete barrier could have prevented this. But I would never look at the exact stretch and direction of road and think, yes, this is going to be a hazard. Obviously it was and needs to change, but my point is that the driver here is at fault and should never be behind a wheel again.

    The city immediately after this made a bunch of changes to the area. Changes I imagine they’d been wanting to make for a while. But the changes never impacted the direction / route this car was going. So that makes no sense to me. They fixed nothing that would have changed what happened here.


  • In this case though, there was really nothing about the street or traffic design that was the problem. This is actually insane.

    The intersection near where this happened is quite a cluster fuck. But not in the direction that the driver was driving NOR where the family was standing And the driver was going so fast it literally obliterated a steel bus stop. Like ripped it out of the ground.

    They’ve changed the intersection, but traffic design had nothing and will do nothing for what happened in this instance.

    Fuck cars. Yet again the best way to kill someone is to do it with a car and call it an accident. It’s actually insane. (I’m not saying this was intentional, but the driver should never be behind a wheel again for starters, and this does need to be punished more than this farce.)







  • Calibration of a printer is very much a cumulitive thing. Looking at your print I think your PA is off, but I would guess that it’s a combination of multiple settings. When calibrating a filament, I usually do a sweep of calibrations, and then sometimes even come back to past steps to rerun since the values can impact eachother.

    I.e. I typically do in this order per brand of filament type. Always starting with the closest preset I can find. Usually the generic version if there isn’t the brands of exact filament as a preset in orca.

    Temperatue

    Max volumetric speed

    Pressure advance

    Flow

    Retraction

    Sometimes back to PA because flow can impact PA

    VFA/input shaping (optional)

    And then toss a tolerance calibration at it at the end, but I don’t typically do this per filament, just do it per printer unless you’re about to print some super tolerance intolerant parts

    IMO your flow / pa are off and combined are causing this. But idk, if you’ve already done both those calibrations then I’m not experienced enough to be able to definitively say what the issue is.

    Edit: OH, one thing to note, you can increase the flow rate, and then in tolerance you can adjust the shrinkage to get the tolerance correct. So in that scenario increase flowrate, and then jump to tolerance and adjust to get the correct dimensional accuracy. That will make orca slicer auto scale the part dynamically so your final dimensions are correct.



  • This comment is correct imo. Read / calibrate the pressure advance. I’ve had especially good luck with the adaptive pressure advance and highly recommend taking the time to calibrate it.

    Its a little bit confusing to do, but once you get the hang of it and do a full calibration sweep it should fix all the ‘corners have gaps’ issues. (Also just any gap issues between line)

    Pressure advance is going to impact any line where the head will be shortly changing directions. So though it typically is corners you can get it with any acceleration change of the print head.
