Moving part on a certain axis

[WillyDevz (Willy)]

Hello, I am making a table tennis like game where I want the racket to move on the Z axis, I made a brief prototype which has a lot of bugs with the movement on the axis, it usually just bugs when you move your mouse too fast. How would I be able to achieve a smooth version of this? Thanks.

This is my code:

local mouse = game.Players.LocalPlayer:GetMouse()

game:GetService("RunService").RenderStepped:Connect(function()
	if mouse.Hit then
		workspace.main.PrimaryPart.Position = Vector3.new(workspace.main.PrimaryPart.Position.X, workspace.main.PrimaryPart.Position.Y, mouse.Hit.p.Z)
	end
end)

First of all, you should do

local P = workspace.main.PrimaryPart.Position
workspace.main:SetPrimaryPartCFrame(CFrame.new(P.X, P.Y, mouse.Hit.Position.Z))

Then, what is the bug you want to resolve?
