V-core3 overheats after homing in 2 minutes and shuts down

Hey everyone. I just finished my V-core3 and yeah the above mentioned problem occurs(see Screnshot attached for the fault). I noticed, that the drivers were getting really really hot quickly just when the printer is homed and sitting there, no active movement. I swapped the three z-axis drivers for the ones I had in my v-minion and the problem was fixed. The drivers are both 2209s but the ones that shipped with the vcore3 where v1.3 while the ones from the v-minion where v1.2(see pictures). Does anyone know what is causing the problem here? Sense resistor is the same on both and they are both 2209 drivers from BTT.
Thanks a lot for your input!
