To test the movement axis X and axes Y configure of the program ready-made Mach3. Set Step per as 100 set Velocity, was 1 400 and defined. Acceleration was 1 400 the test set, in the program Mach3 within the core X 5 value, found that the error of the cutting machine foam equals 0.49 centi meter. Percentage error of 0.72 percent. From the test, the foam cutting into 3 size, font, found that the foam cutting of each size. The percentage of errors that 18 cm accuracy of 96.78 percent size 36 cm accuracy was 87.08 percent. The size 57 cm accuracy was 68.70 percent. The accuracy of the foam cutting is acceptable. The size of the foam with precision the most.
