Hi KZX,
This is Ben from Thunder laser.
Regarding your problem,my answer as below.
1.The lines are not staight but curved.
In the scan mode of X_swing,there is a shake range from belt and motor while engraving speed under 400mm/sec and less.
how to fix it,you just run on 500mm/sec and more,it's not necessary to work on low speed if it can run fast.
The Max speed is 1000mm/s,please just set speed as 500,600,700 and so on.
or you can select scan mode as X_unilateralism,in that mode,it will process slow but will make a better result at whatever speed you set.
2.The edge is not smooth.
For X-Swing, there is a deviation and gap due to the belt driver as following shown:

you can adjust the Reversal interval for scanning.(Each machine have factory defaults but it's not perfect for a single machine).
and you can test the perfect value for it by yourself. In general, more speed need more reversal interval.
where is it, see pic below:

there is a parameter of it for your reference,see attachment.
