Problems solved by technology

[0002] In the field of 3D printing, especially similar to cake printing, if the mobile platform cannot move at a uniform speed, pastry accumulation will form when the flowing pastry is sprayed down; in the field of laser printing, if the mobile platform cannot move at a uniform speed, it will cause inkjet printing. Uneven, thick in some places, thin in others
[0003] When the single-chip microcomputer drives the two-dimensional mobile platform, the calculation of the slash and the arc all involve floating-point calculations, and the calculation of the straight line does not involve floating-point calculations. Affected by the calculation, it will cause the straight line to go very fast, the oblique line to go very slow, and the circle to go even slower. This is the uneven walking of the single-chip microcomputer. The main reason for this situation is the low frequency of the single-chip microcomputer.

Embodiment Construction

[0037] Single-chip microcomputer-driven three-axis uniform movement method, such as figure 1 As shown, the method consists of the following steps:

[0038] Step 1: Convert the user's plane movement command on the X and Y axes into a polyline movement command;

[0039] Step 2: Combine the polyline movement command with the Z-axis movement command, and convert them into step-by-step movement commands for X, Y, and Z axes;

[0040] The third step: save the stepwise movement instruction codes of the X, Y, and Z axes into the memory;

[0041] Step 4: Read the step-by-step movement instructions of the X, Y, and Z axes in the memory, and drive the movement of the three axes.

[0042] In actual work, the above process can also be stored in a file rather than in the memory after the user’s movement command is converted into a three-axis step-by-step movement command. The next time the user will directly send the file to the three-axis Shaft sliding platform.

[0043] In actual work...

Abstract

The invention relates to a triaxiality uniform speed moving method driven by a single-chip microcomputer. The method is used for a triaxiality sliding platform and is characterized by comprising the following steps: (1) converting plane moving instructions on an X axis and a Y axis by a user into broken line moving instructions; (2) combining the broken line moving instructions and a moving instruction on a Z axis, merging and combining instructions, and converting the merged instructions into step-by-step moving instructions on the X axis, the Y axis and the Z axis; (3) encoding the step-by-step moving instructions on the X axis, the Y axis and the Z axis, and saving the encoded moving instructions in a memory; and (4) reading the step-by-step moving instructions on the X axis, the Y axis and the Z axis in the memory, and driving triaxiality to move. The method has the advantages of converting the triaxiality moving instructions by the user into the step-by-step moving instructions in advance, and saving the step-by-step moving instructions in the memory, wherein a moving platform does not perform complex floating operation during operation, so that the effect of moving at a uniform speed is achieved. When the method is used, a CPU with a lower frequency can be adopted, so that the cost of products can be effectively reduced.
