@Jorge thanks for updating us.

I think the heatsink has no effect

the bowden retention mechanism can have an effect. A small play can lead to retraction problems.

I.e. this heatsink from aliexpress is very close to the e3d one

whereas this one is using a push fit connector which can fail after some time

For what it's worth the E3D tool changer uses stall detection and it's CoreXY and they claim it's reliable enough in their testing. So it can be done, though I personally don't think it's the best way to go.

Can you post your full config file?

Are you dropping the motor currents for homing?

The speed needs to be fast enough to trigger the stall. If it's too slow it won't register.

I could verify it. changing extruding speed from 0 allows no jerk. But when changing the speed from one direction to another, the jerk works fine.

Ahh how could I not see!? So it really was a noob problem. Now it works. Thank you so much!
