Testing of the Precision Matthews PM25MV mill CNC conversion kit from ArizonaVideo99. The stepper motors are Leadshine closed loop 283 oz.in., smaller than what are commonly used, but with plenty of power. The mill acceleration is 30in/s^2. LinuxCNC is the controller and the Pico Systems Universal Stepper Controller is the pulse generator. Here we test the backlash and feedrates, and to demonstrate available power, track the following error from the servo loop while loading the head with additional weight. The PM25MV is similar to the Grizzly G0704 and the Titan TM25V mills, so this video may have wider interest.
