I have been running 3d prints on my A350 for the past few days and decide for one print I needed a ramp to test the quality of the bottom of the print. I was using a brim on these prints. When I added a raft with Luban and started running, the printhead started gouge the bed. I tried to adjust the z-offset but trash the other side of the print sheet. Is this a known issue with the latest version of Luban? I understand there are better slicers out there but I’m an amateur and want the ease of use to use the software from the same maker of the machine.
