Hello, Didn't experience probs with SD cards on Ulticontroller. I installed the controller immediatelly at assambly of the UM, so when upgrading the firmware to Marlin, it probably correctly installed for use of Ulticontroller straight away. I do have an issue though, with SD cards, in Cura 13.03. After slicing a file i want to copy it directly on the SD card though this always throws the following error message at me "failed to copy file to sd card" Any ideas? Tnx!
Something definately went wrong when i tried this (downloading and hitting print) on the UM, i guess that you'd better post the stl files so UM users can create optimized gcodes (in Cura eg) Grtz
