10. FAQ
Q1: Will the characters below 1CM be deformed?
When graving small characters, please set sharp-angle compensation in the software. For example, in Wentai plotting software.

Sharp angle 0.25
*
The compensation ranges within 0.1-0.7, more often we set it to be 0.25 mm. In addition, the plotting speed of the cutter
shall be set below 20.
Q2: Why there is an additional stroke after finishing cutting
1. Check if the tip of cutter is flexible when it is up and down.
2. Check if there are some problems on the files you are working on.
Q3: Why zigzag happen to the cutter?
As cutter motor features high power and speed, so the cutting speed shall be adjusted according to size of character. Generally, to cut
small glossy characters with high requirement for precision, the speed shall not exceed 40.
In most cases, the speed at the shaft 50 ~ 60 is favorable. To cut big characters of large quantity within shortest time, the speed can be
70 ~180, but since step distance of motor is so long that evident zigzag occur. Therefore, you should set the speed to specific size of
characters, and the relationship between speed and size of characters please refer to following table:
Size of font

Speed
＜
10 10-20
10-30 30
30-50 40-50
50-500 60
＞
500 70-80
Q4: Why the paper deviate when it runs by a large margin?
The paper feed bracket containing paper roll shall be completely parallel to paperweight wheel, for big roll of materials, loosen it prior graving
to prevent excessive obstruction when plotting or graving. For the machines with four paperweight wheels, when plotting big image or
characters back and forth, use the two paperweight wheels at sides instead of press the four down simultaneously. Unequal abrasion of the
two wheels also may result in deviation of the paper; in worse case replacing wheels is needed.
Q5: Why the machine feel tingle?
