Well, the filament is not the problem, since all motors are moving, I really recommend changing the software. Download Cura, it’s a free and much better slicer than repetier host. Download link: https://ultimaker.com/en/products/ultimaker-cura-software
Download and install it, then put your model in there, don’t do any configs, just keep it in the recommended settings. Plug the SD Card in your computer, then click in the bottom right on the “save to SD Card”. If it doesn’t work just check if the unity (C: D: E: etc.) is right. After that, the program will save the .gcode file in the sd card. Eject the card safetly with the windows ejecting system, or just click on the eject button that will show up after you save the file in the program. Plug the SD Card in the printer, the slot is usually in the back of the LCD Panel, or in the motherboard. Plug there, navigate in the printer menu and start printing the file. See if it works, this should solve the problem.
