X and Y axis motors heating

[rlima-projmec]

I bought a creality v4.2.2 board with A4988 drives and a 4.3 inch display (not touchscreen). I installed firmware E3V2-ManualMesh-3x3-v4.2.2-v1.3.5.b.
I noticed that the x- and y-axis motors are heating up to a reasonably high temperature. I would like to know if there is any parameter in the firmware that determines the ideal current for these motors or if it could be the driver with high Vref.

you need to change your vref. thats what i see heat up motors the most is too high vref. so many things go into this. 2 boards i ordered had vref set so bad that im surprised stuff didnt burn

this is taken from a vref cacl site i use. do your own research first.

assuming you have stock motors which are 1.5a
red Ω r050 vref is 0.60
red Ω r068 vref is 0.81
green Ω r100 vref is 1.2
red Ω r200 vref is 2.4
