Hi there, I recently purchased and built the tronxy x1 3d printer. Unfortunately,  my z axis has a problem. Whenever I try to home my z axis, the motor makes a loud sound and slowly moves down. Also when it moves down I have to poke the metal shroud around the threaded rod to get it to go down. Also whenever I try to print something, my z axis can't go up =( PLEASE HELP ME!!! 
Hello everyone. I have an issue with my printer. As you can see from the pictures, the infill is not touching the perimeter everywhere. Could you please let me know what can I do? I am using the Simplifiy 3D slicer. You can see in the photos that on the first layer everything is really smooth. But the end layer isn't. And is irregularly touching the perimeter.

Hi to all on the forum. I've had a 3D printer for a while but still consider myself a newbie. I've been luvin this printer & have even used it to print parts for a new CNC router I'm building. My printer is a TronXy X5 that I have upgraded with extra linear bearings on the Z axis. I am curious about one thing though, the wavy lines that appear on straight sections on the X axis.
