Hi @Austin913 - What post processor are you using when saving your toolpaths out of Fusion 360? I’ve been using this one from @Strooom successfully for a while: A better Fusion360 - GRBL PostProcessor
Also, in your setup, what do you have selected for WCS? Someone can correct me on this, and probably explain it better, but I always set that from ‘0’ to ‘1’ (you can find this on the third and final tab in Setup). Also make sure there are no G28’s called out in your g-code.
