So looking for some help here. I have now tested 4 filaments and 4 different prints off of the USB drive with. my C2 without issue. But as soon as I try to print a custom item from Thingiverse the feed gear skips and acts like it can't feed the filament. It doesn't have this issue in the warm-up or the initial line it draws, just when the printing starts. I did some searches on the forum and some recommended seasoning the extruder, so I was able to push the filament in while it starts printing and pulled off a quick print for an oiler for my filament, and I have now been seasoning it, but still not having success starting other prints. I have made sure CURA is creating the file using the right material (Robo PLA) and I am using the Robo Profiles. Any thoughts, I would think the gear might not be aligned but it works without a hitch when I use one of the files that come with the printer.
