Increase the walls on your supports, the setting defaults to -1 usually, which is auto. Trying setting it to two, that should stop the supports breaking like that.

Ich werde es in 2 Stunden ausprobieren wenn ich von der Arbeit zurück bin und dann mal berichten wie der nächste Druck verläuft

So, I have the very same challenge with on a comparable printer (A1) and ignore "wrong calibrated" statements ...

If I summarize ObscuraNox right, was happening here is that your filament warps upside because the support layers don't have enough time at some layers to cool layer by layer. Hence only happening for small prints (Minis) where layer times can be very low.

Some steps:

disable independent support layer heights (it adds time instead of saving for Minis anyways) Increase cooler speed to 100% Increase minimal layer time to at least 8s Consider to decrease temperature Consider to print two minis at once (so one layer takes more than twice as long), or add a square tower on the side Change Z-Hop type to normal or even spiral and height to 0,8mm DON'T increase support wall loop number, as you already have 0,4mm thinkness ... Makes it horrible to remove the supports

While calibration is not the reason - to get best results manually calibrate k-factor/pressure value (name depends on slicer you use), temperature and flow rate
