Why is my build plate z level getting messed up

[fontseeker]

Never used makerbot but my guess is maybe it just isn't good at supports? Might try a google on that one.

I have seen Makerbot printers work perfectly with supports but it is my first time using a QIDI, for some reason every time it gets to the support the printer starts printing midair, like it didn't place the supports but the building plate keeps going down:

In other words, the print goes flawlessly, but as soon as it reaches the support structures, the extrude slowly starts to print midair. No idea why

This are my support settings:

I can't figure out what it is that is messing my print when I use supports.
