Hi, I work in an acoustics lab and we've been using using one of the Open Builds CNC machines with a microphone replacing the router to make measurements in our experimental setup. These have all been done in a horizontal plane so things have gone quite swimmingly. However we are now more interested in larger 3D volumes and having more height is crucial. One idea we had was to take something like the Lead Machine 1515 and orient it so the x-axis is mounted to the floor with the wheel mountings running vertically. This would roughly provide us the range in the newly oriented X-Y-Z directions however all the CNC designs I've seen look like they were intended to have the CNC machine flat to the ground. We would be attaching the build to the floor for stability purposes. It strikes me as if a lead screw driven system would work much better combating gravity compared to the belt drives. However it seems under the extra strain this could potentially casue the screws to bind or we could run into limits on the stepper motors in terms of the torque requirements. Has anyone had success in making a build where the machine more operates more in a vertical plane? Thanks, Graham
