How to quickly replace the flsun-V400 nozzle kit

When the nozzle is driving on the surface of the model, it will make a scratch sound when filling. The nozzle diameter is 0.4mm, the layer height is 0.2mm, and the dense edge routing will cause part of the filament to overflow, which is 0.2mm higher than the layer height, or the filling pattern has the intersection of the same layer. Because the nozzle moves at a high speed at the same layer height, the overflow material will have resistance when the nozzle passes through after cooling. When the nozzle passes through at a high speed, there will be a scratch sound, and in serious cases, it will cause step loss, resulting in staggered layers and model falling off. Nozzle tilt
Countermeasures:
1. Set the extrusion amount in cura to 85% - 90%
2. Change the hatch pattern to spiral in cura
3. Set in cura to reduce idling speed and increase nozzle temperature

5 flsun400 printers
original board dump, replaced with MKS Robin nano v3.1
Problem, the plastic is stuck in the thermal barrier, I'm waiting with Ali for a new one made of titanium.
On which the board was replaced, problems with printing, overextrusion + overheating
As for the printer, it is a very difficult print head to set up. My renovation is in full swing.
I apologize for my translation, I don’t get along with the English language.

V400 真的是我用過最難拆噴嘴的機器,尤其又拖著一條長尾巴的時候~
