simple fff 3d printer

Hello everyone,So i have this simple cartesian 3d printer and i really want to keep the cost down for this one. The problem i have is that i found some parts on biqu.equipment the motherboard- a btt skr v 1.4 with wi-fi module, steppers- btt s42b, extruder- direct drive titan module and for the hot end a j-head.My questions are about the motors and the hotend. Have you ever used either one of these? And even if you didnt what do you think about them ? Do you have any experience with the drivers on the s42b’s driver? Are 32 “subdivisions” enough microstepping to keep the noise level down?I apreciate any imput, even if its just an educated guess. Thank you.
