MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I had horrendous prints for quite a while. I downloaded the latest version of Cura from the ultimaker website and started from scratch. I used their Anycubic Mega preset (Settings > Printers > New) and that preset - despite having almost identical settings to what I was already using - seemed to print perfectly.
I had previously tried bed levelling, extrusion speed, flow rate and temperature settings to fix it, but it seems the new profile done the job.
