Hello, Please can you help? I have been testing parts using a .4 nozzle and I have achieved a good surface finish with regards to no unwanted lines across my top surface. My next issue is tiny blobs and strings only around holes. Please advise how to overcome this? Also, I cannot seem to enable my retraction height settings in Cura. For some reason they are hidden off. Any ideas how I can un-hide these please? Thanks very much, Matt
