I'm a newbie with a question. I have a Shark HD4 and am running V-Carve Desktop 9.012 and Next Wave CNC stock control software. I've made 3 projects so far. The 2 3D projects have a strange occurrence when the tap files start. I hit the start button and the bit will navigate to 0,0 XY and then it will lower in to the work before traveling to the next XY location where it starts to carve. At that point the bit will raise when necessary to navigate to the next XY location, lower and carve. It works normally at every step of the rest of the project. Whether I'm running the roughing file, finishing file, V-bit engave, etc is irrelevant. The initial move lowers and carves everything in its way until reaches it's starting XY. Any ideas? We purchased the system from Rockler 2 weeks ago and I updated the Vcarve and Next Wave software to latest versions. I have not done a firmware update to Shark controller and am not sure yet if it even has newer firmware available.
