@phaedrux Hello Phaedrux,
Thank you for your reply.

pspp is Tool Changer Prusa Slicer post process cript. Its github address is: https://github.com/mkudzia84/toolchanger-pspp/tree/master

I am currently on a business trip and do not have a configuration file in my hand. I will release it to you when I get home. The firmware version is v3.1.1.

The firmware I currently use is the configuration file of Nibbels, and the github address is: https://github.com/Nibbels/e3d-toolchanger-config/tree/master

What kind of a printer is it? E3D tool changer?
CoreXY tool changer, but what does it look like? Photo?
How heavy would you say the print head is with a tool loaded?
Direct drive or bowden extruder? A retraction distance of 7.5mm would indicate bowden. Have you tuned retraction yet?

Your max print speed is also quite low.

M203 X3000 Y3000

Only 50mm/s which is half the speed you've set for travel moves. So you should at least set your max speed to match what you want to use for travels. M203 X6000 Y6000

On first glance I would say your jerk values are a bit low, meaning the print head will slow down on corners, which can make bulges at corners more pronounced.

M566 X300 Y300

Try M566 X900 Y900

If you are using a Bowden extruder start with a pressure advance value of M572 D0 S1 and see how it goes.
