We are guitar builders transitioning from hand crafted to CNC built guitars. We are using a K2 built cnc machine with Rhino CAD and Rhino CAM. The machine software is KMotion by Dynamotion. We ran a prototype and it went well. We made a few adjustments to the prototype and ran them and the machine dove down in Z and cut the neck in half! We have reviewed the CAD and CAM and there are no code errors that would cause the machine to do this. We do not know if the Kmotion software is at fault or the machine has a switch not connected. We are new to this and could use some help in trying to get the machine up and running. K2 is of NO HELP AT ALL. Please advise if you can help. We are located in the North Houston TX area You can also reach me at [email protected]
