First of all please read the instructions that you received with your CNC on the USB stick.
Read the User manual of UCCNC which can be downloaded on the official CNC Drive page (https:\\www.cncdrive.com/UCCNC.html) or you can find it on the USB stick.
Our XP-Line and X-Line have auto square when you do homing of all axis. For fine-tuning of squaring you have two screws for the Y1 and Y2 sensor in front of CNC that are used for squaring.
Manual for installation can be found on our USB stick or can be downloaded on the CNC Drive page ( https:\\www.cncdrive.com\AXBB.html). With our CNC you will get an ethernet cable for direct connection so setup information can be found in manual chapter 5.
A convenient method to ensure the table axes are aligned along the same plane is to use a long level and adjust the leveling feet such that the table is level along X, Y, and diagonally. This is very important! When to re-check: When your machine is moved to a new location in the shop.
