The procedure that follows gives instructions on how to calibrate the Z-axis on the AON-M2 and AON M2-2020 machines.
Estimated time: 30 minutes
The instructions that follow are for the AON-M2 and AON M2-2020 machines only. Refer to Z-Axis Calibration (AON M2+) for the AON M2+ (CE), AON M2+ (R-NZ) and AON M2+ machines.

The instructions that follow shows the improvements added in software application v21.12.06.18.00.
Use the Graphical User Interface (GUI)/web browser to confirm the software version that is installed on your AON-M2 and AON-M2 2020:
If your machine does not have the latest software version, refer to the Software Update procedure.
Make sure that there are no prints on the build surface. Remove print(s) before the procedure that follows is started. Failure to do so can cause a collision and cause damage to the machine component(s).
B) and build chamber (
T2) target print temperatures. Refer to Heat Build Chamber Components to select the recommended temperatures.
The wait time for build chamber components to increase to a stable temperature is one to four hours. Refer to Heat Build Chamber Components for the recommended list of time necessary for material that is to be printed. It is necessary to wait for the full recommended time to get the build chamber components to a stable temperature. Do not use the target temperatures, found on the GUI/web browser, to measure the temperatures in the build chamber during this procedure.
Machine components are hot at this point. Persons are recommended to wear the correct personal protective equipment to prevent injuries.
Filament must be retracted from the hot end assembly(ies) before a mesh is probed. Failure to retract the filament can cause damage to the hot end(s) and/or the probe assembly(ies), and can give incorrect Z-probe calibration results. If filament is not retracted, the GUI can notify the user with an error message.
Use the GUI/web browser to retract the filament as follows:
The selected toolhead target temperature must be ±10°C (±50°F) from the bed target temperature when a mesh is probed. The software will not let the machine probe the mesh if the toolhead(s) temperature(s) is(are) set incorrectly.
The toolhead(s) temperature(s) cannot be changed when the mesh probe sequence is in progress. The GUI/web browser will notify the user if the temperature is changed when the mesh probe sequence is in progress.
On the GUI/web browser, select Control > Z Calibration. On this menu, the user can do the actions that follow:
Select the Bed Configuration that is installed in the machine.
The default grid can be resized to probe a smaller print area, if necessary.
The mesh uses different color points which are as follows:
Restrictions on Probe Bounds are as follows:
|Probe Bound||Default Value||Minimum||Maximum|
|Left||35||5||Right - 30|
|Right||415||Left + 30||445|
|Front||35||5||Rear - 30|
|Rear||415||Front + 30||445|
To reset the Probe Bounds to factory default values, select Reset.
Installing the AON-M2 High Temperature Build Plate into Simplify3D® only applies to Simplify3D® V4.
To install the AON-M2 High Temperature Build Plate into AON-M2 High Temperature Build Plate into Simplify3D® V4, refer to Slicer Setup.
Use the instructions that follow to enable the build plate in the Simplify3D® environment:
To reset the Probe Bounds to factory default values, select Reset.
The X and Y probe counts are the number of equally distanced points, along the X and Y axes, that are used to build the probe grid. The user can edit the number of X and Y probe counts, if necessary.
A higher Probe Count will add more definition to a grid, but a longer quantity of time is necessary to do the mesh probe procedure. A lower Probe Count will decrease the time necessary to probe a mesh, but will give less definition than a Probe Count with a higher numerical value.
To help the user plan the probe sequence, the coordinates of key points on the build platform are as follows:
Do not probe the external area of the default bounds. This can cause the bed to collide into the toolhead(s). The default grid will probe around the bed screw heads that hold the PEI plate to the aluminum bed base.
Do not use Probe Bounds that will probe directly onto the AON-M2 High Temperature Build Plate screw heads. This can cause error(s) in the mesh.
AON3D recommends that the build platform be probed before every print. Probe the build platform, calibrate the Z-axis, and/or adjust the Z-offset, when:
The two toolheads Z-axes must be calibrated when the two toolheads are in operation for the same print.

• If the probe assembly does not compress, or gets stuck in the compressed state, select Stop to cancel the probe sequence. This can also trigger a Z probe triggered prior to probing error notification on the UI/web browser. Make sure that the filament has been correctly retracted from the hot end(s). Refer to Retract the Filament.
• Each point on the grid will be measured five times during one probe sequence.
• The selected toolhead will move to the center of the X-axis, and to front of the Y-axis, of the probe grid.
• The nozzle will move very near to, or possibly, touch the build platform, after the probe sequence is completed.
Closerto adjust the distance between the build platform and the nozzle.
Make sure to give the Z-axis the time necessary to move in the selected direction.
Make sure the probe is not compressed at this point. This can occur if the Z-offset is set too near to the build platform. To prevent toolhead collision(s) onto the build platform, keep a small distance between the nozzle and build platform.
0.1mm, then select
Fartheruntil there is a distance between the nozzle and the build platform.
Closerbuttons to adjust the Z-offset until the nozzle is approximately 0.1 mm from the bed platform.
• Do not home
XYZ after the probe sequence has been completed. If the Z-axis is homed, it can cause the mesh to move and give incorrect results in calibration. Use the jog function to move the toolhead(s).
• To stop the probe sequence, select Stop at any point to cancel the procedure. This stops the probe sequence, and the active toolhead returns to the home position. If the sequence is stopped when the toolhead is in motion to the home position, the toolhead will stop. Home XYZ after toolhead(s) is(are) stopped.
• All probe values are reset to the default configuration of 30 mm when a probe sequence is stopped. In the UI/web browser, select Terminal and input M-code
M501 to get the values from the last correct probe sequence.
If a print uses the two toolheads for the same print, the two toolheads must be calibrated along the X/Y-axes before a print is started. The X/Y-axes calibration procedure adjusts the coordinate system of the two toolheads to be in line with each other. Refer to X/Y Toolheads Offsets Calibration.
After the build surface has been probed, filament must be extruded from the hot end(s) before a print can begin.

All Fused Filament Fabrication (FFF) Simplify3D® profiles provided by AON3D include brim(s), skirt(s), and/or raft(s) to help adjust the Z-offset. Refer to the Material Guides section for more information. To manually add brims, skirts, and/or rafts, refer to Simplify3D® Additions tab.
