upgrade parts for the KP3S (Pro)

upgrade parts for the KP3S V3 & Pro S1 the y-axis part is needed if you upgrade the y-axis on the KP3S Pro S1 with linear guides. this kit costs 35$ and i recommend to do it. best to do it on the Kingroon site directly: https://kingroon.com/products/y-axis-linear-guide-upgrade-for-kingroon-kp3s-pro after the upgrading the end switch didn't fit. therefore the small adapter. additionally 2 screws M2.5x6mm are needed. with this block fits both: the distance (end position y-axis) and the switch flag to the screw of the bed. ___________________________________________ the second component (guide) is for Pro S1. it holds the hose above the filament sensor. the guide remains constant and the filament does not break at this point. simply push the block over the hole. if the filament sensor does not sit exactly under the hole in the sheet metal, then simply bend the sheet metal slightly forward or backward on the inside. ___________________________________________ third component is an alignment aid when the linear axes of the y-axis are placed and screwed on (see video from kingroon: https://youtu.be/8f4uOHlxcGI). there are 2 parts. with the larger one, the alignment and possition of both rails can be done at the same time (print the long part 2 times). ___________________________________________ other parts work for the KP3S V3 and KP3S Pro S1: attachment to the 5015 fan. the air is brought to the left and right for better component cooling. this allows higher speeds and nicer overhangs. relief component for the pressure lever: the hose is plugged into the lever. due to the movement of the x-axis, the lever is repeatedly loaded, which leads to wear in the guide (motor shaft and ball bearing). the relief component is simply screwed on above the sheet metal. the hose is plugged into the relief component and the filament always arrives in the extruder at the same angle and without lateral force. this considerably increases the service life of the extruder. ___________________________________________ i also recommend printing with the flexible pad for the heatbed. i got the printer with a glass plate and replaced it. i ordered 235x235mm printbed pad. i cut it to 210x210mm. https://aliexpress.com/item/1005003710805536.html https://youtu.be/tjVy891SuPk
