1.whether the X-axis beams was paralleled?
2.Y-axis belt tension was the same?

Belt friction with the rotary axis

Yes, the laser can do it

The Y axis is rotary axis.

good!

1. calibrate the beam
2. minish the scan interval

It depends on your parameter settings

No RI setting knowledge. This picture was made by me.

There is a problem with the wiring of the laser power supply to the mainboard.

you set wrong reverse interval .

you are welcome :cheers:

what laser software do you using?

Hi,
you need calibration the reverse interval.

This is Topwisdom main board.

Hello,

I need the picture of board and display screen.

1. About the line wave you can lower the X axis maximum acceleration.
2. The cutting graph 352662
I think you need recalibrate the laser from 2th reflecting mirror to 3th.

step 1: click file

2: vendor settings

3: read

4: click-------X axis step length350696

5: change like this 350698

Hello,
You need change the X axis pulse equivalent.
