not sure what is causing this but if i set the slicer to fine or medium quality everything prints fine if i set it to fast and do a preview there is a layer missing. when printing on fast you can see where the layer is missing even tho it didnt mess the print up to bad. not sure why changing the quality would cause this issue i checked all the setting they are the same other then the layer hight being changed for the dfferent quality.
this is with the newest 3.01 version
