# What does it mean when Marlin slows down on corners?

## What does it mean when Marlin slows down on corners?

What it means for Marlin (the firmware in all UM printers and in 90% of printers out in the world) is the speed the head slows down to on corners.

## What happens when you go around a corner at speed?

Mathematically if you go around a corner at speed your acceleration and (real) jerk go to infinity. So to handle the maths, either you can’t go around a corner at speed and have to keep stopping, you actively round the corners slightly to avoid infinite jerk/accel, or you just completely fudge the maths.

## Which is the derivative of acceleration in Marlin?

Correct me if I’m wrong, but I’m pretty sure that the implementation in Marlin is not the derivative of acceleration and “jerk” is just the highest allowable instantaneous change in velocity vector.

## Where is junction deviation setting stored in Marlin?

The Junction Deviation setting is stored in memory using Menu –> Configuration –> Store Settings and I have confirmed the values remain in memory after cycling the printer. If Classic Jerk is disabled in Marlin firmware, would an M205 X [Jerk] Y [Jerk] Z [Jerk] command before a print enable Classic Jerk for that print?

## Is the Marlin firmware for a 3D printer perfect?

I’m using the Marlin firmware (1.1.0-RC7 – 31 July 2016) for a 3d printer. Currently the printing is not perfect due to slight inaccuracies in movements along the x and y axis.

## Is there a way to Speed Up 3D printing?

You’ve started 3D printing but you realize that prints take a lot longer than you expected. This is something that many people think about so they look for ways to speed up their 3D printer without sacrificing on print quality. I’ve looked into various methods to achieve this which I will explain in this post.

## How to increase print speed without losing quality?

8 Ways How to Increase Print Speed Without Losing Quality 1. Increase Print Speed in Slicer Settings. Honestly speaking, print speed doesn’t have the most significant effect on… 2. Acceleration & Jerk Settings. Jerk settings are essentially how fast your print head can move from a still position.
