Specification AirFlowCapacity : 200 cubic_meters_per_hour Brand : ChowThink BulletPoint1 : Version Description: This version summarizes the advantages and disadvantages of all previous versions and is developed using synchronous belts instead of dual motors. Due to the speed difference between the dual motors and parameter differences between different motors, models driven by dual motors often experience Z-axis noise, shaking, and other issues. This is also the mainstream direction of technology. New flagship models such as X1 and K1C have already replaced dual motors with single Z-axis motors. BulletPoint2 : 【SFU1204-365mm Ball Screw kit】2Pcs Ball Screw SFU1204-365mm with ball nut+Decoupling device+Special CNC machining screw seat+Special CNC machining motor support+Accessories(Motor not included) for Ender3/pro/v2/neo dual Z-axis Upgrade.This kit is compatible with the ChowThink linear rail kit.【SFU1204-365mm Ball Screw kit】2Pcs Ball Screw SFU1204-365mm with ball nut+Decoupling device+Special CNC machining screw seat+Special CNC machining motor support+Accessories(Motor not included) for Ender3/pro/v2/neo dual Z-axis Upgrade.This kit is compatible with the ChowThink linear rail kit. BulletPoint3 : 【Higher Precision&Smooth Running】The trapezoidal screw belongs to sliding friction, but the ball screw is rolling friction, Through the movement of the ball, the heat is less and the precision is high,The efficiency is 2-4 times than the trapezoidal screw,which can make the Z-axis screw run more smoothly, which can make your printer capable of printing with higher precision. BulletPoint4 : 【Compatible With Linear Rails】This kit is compatible with Z-axis rails and comes with all accessories. Just prepare two appropriately sized wire rails and six M5 * 50 screws. BulletPoint5 : 【Parameter Specification】1.Processing Mode:cold rolling 2.Screw diameter: 12mm 3.Pitch: 4mm 4.Lead: 4mm 5.Screw material: S55C 6.Nut material: 20CrMoV 7.Accuracy class: C7(the stroke error within any 300mm length shall not exceed 0.05mm) BulletPoint6 : 【HIGH-QUALITY Material&Accessories】Ball screw is precision machined from high strength steel, and equipped with special customized CNC machining screw seat/motor support/decoupling device,so that it has higher precision and stronger load capacity. BulletPoint7 : Notice:1.The stroke of SFU1204 is 4mm, which is different from the original T-screw,please change the pulse value from 400 to 800. If the lead screw is a little rough at first, please turn it several times, because new mechanical products need to be run in. If you have any installation questions, please feel free to contact us, we will reply you within 24 hours. 2.This kit is not compatible with Ender3 S1.

Compared with the original T-screw, the ball screw can bring higher precision, printing speed, load, smoothness, service life, etc. Compared with T-screw, the ball screw has different friction mode, rolling friction has less resistance and more stable running track. In addition to the advantages in principle, Whether it is material or processing accuracy, ball screw requirements are much higher than T screw. Considering weight, size and accuracy, this kit is SFU1204 with 12mm thread diameter and 4mm stroke.If you have any installation questions, please feel free to contact us, we will reply you within 24 hours. At the same time, you are welcome to enlighten any defects or suggestions related to the product. Your opinions are our driving force for continuous improvement. Our belief is that we are willing to make 100 percent efforts for one percent progress.
