Ender-3 and Newbie Upgrades: Tenth Upgrade (dual-z)
This text has been automatically translated using Google Translate.
The tenth upgrade is not important, but can help you with print quality, especially in the case of a direct extruder. This is the second Z axis.
Why is it important?
For simplicity, imagine moving the entire weight of the direct extruder / hotend to the right-hand side of the X axis. If you have a direct extruder, the difference may be much greater. In addition, if you leave the printer idle for a long time and your hotend stays on the right side of the X-axis, the Z-axis wheels may become damaged and begin to create artifacts on the print when the Z-axis moves.

| A slightly more expensive variant with a second Z engine. The advantage is that you don't see the belt anywhere. But this is the only advantage. The disadvantages are many more. For example, you need a second driver to drive that engine and customize the firmware settings. The second option is to use the enclosed cable and connect two motors to one driver. However, this means that the driver will not supply enough power to both engines and will need to increase the output power from that driver. Well, that will result in that driver's temperature being raised during performance. In addition, both sides of the axis are not synchronized, and without automatic calibration, you may run the risk of one axis lower than the other. | Simpler and actually better solution. The movement remains on one motor and one driver. The driver does not overheat. The other Z axis is also controlled across the belt. Thanks to the fixed synchronous connection, there is no risk that one side of the Z axis will deviate and cause printing problems. |
