Artefacts when printing parallel to X axis
I have a TronXY X1 myself. This kind of artifacts appear along the X-Axis as it is a cantilever design - and if not properly secured, will start to osctilate when moving sharply. This can be fixed in several ways:


print slower. By making the movement changes less abrupt, the oscilation can be reduced.
stiffen the X on the Z. Often, the X1 has a somewhat wobbly X-Axis. To fix this, someone calling themselves FabianFriethjoph did design a 'bracket' that is intended to keep the wheels aligned and under a little tension. https://www.thingiverse.com/thing:2275654
