¶ Manual X/Y/Z Toolhead Alignment
¶ Tools required
- Laptop or computer
¶ Synopsis
Sometimes it may be desirable or required to manually adjust the X, Y, or Z offsets of the second extruder head. The wizards generally complete these alignments to a degree necessary for success, however some advanced users may wish to further tune these offsets.
In this article, we'll cover using the SET_OFFSETS gcode command to manually and permanently adjust the X, Y, or Z offsets of the second extruder.
¶ Key tips
- When adjusting the Z offset, negative numbers make it move closer to the bed, and positive numbers make it move farther from the bed.
¶ Pre-requisites
- Access to the printer's UI in 3D Labs Studio (or web browser)
¶ Instructions
- Home the printer
- Navigate to the console in the printer interface.
- Issue a T1 gcode command to make the second head active.
Don't forget the T1 command above before proceeding. You won't be able to view the current offsets without first making T1 active.
- Retrieve the current X, Y and Z offsets with the GET_POSITION gcode command:
Note the X Y Z offsets as shown in the photo above. We recommend writing these down in case you need to restore them.
- Change the desired offset using the SET_OFFSETS GCODE command. In this example we change the Z offset with the command SET_OFFSETS Z=-0.02
This changes the Z offset to -0.02. This means that T1 sits -0.02mm lower than T0. If you want to raise the distance of the nozzle, add to the existing offset.
- Issue the T1 command again.
- Confirm the change by issuing the GET_POSITION command again:
- The offset is now permanently saved to the firmware and you don't need to do anything else.
