Done all that, and made a few changes including the name, but the sd card is owned by root, its vfat I guess and I have no rights to save it as gene, nor can I sudo to change it with chown. The save menu is disabled for anything but /media/sdf1. WTF??? finally found the save file option, and saved it to my linuxcnc/nc_files dir. Then sudo chown root:root, then a sudo session of mc was able to copy it to the sd card. Why the hell did they make that a root only function? THIS IS USER SHIT! Anyway, sudo sync, sudo eject. And its warming up for the next print now. Estimated 6.6 hours. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
