On the Creality Ender 3v2, the manufacturer lowered the heatsinks of the 2209 stepper motor drivers and replaced the native heatsinks with these. Also, Creality set the stepper motor drive voltage too high. I lowered the voltage of all 4 drivers until the XYZE motors were warm and not too hot. This fixes the layer offset issue. I used hot melt adhesive for the heatsink instead of the thermal tape found on these heatsinks. I took off the thermal tape and taped it to the stepper drivers. My two Ender 3v2 are working very well now. BTW, Creality v4.2.7 motherboard uses the same black heatsinks instead of blue ones.
