The best part about using repetier host is that I can make my own designs without having to pay someone else for a custom one. This also saves me money because it allows me to create things myself rather than paying someone else. Sometimes there are errors or bugs that cause issues. There is a lack of tutorials online as well as a poor community support system. If you're looking for something where you don't have to pay for design templates then this is a great option. I am able to customize almost everything about my 3D printed items. It has helped me save money by learning how to do all of this myself.
