2. Machine Adjustment

After homing, the default position of the CC1's Z-axis is at Z=0. Due to assembly error, the height of the Z=0 point above the PCB may vary slightly for each machine. This step is mainly to determine the default height of the PCB surface, which will be used to set the Z height for the Board/Panel in OpenPnP jobs.

1. Preparation

Mount a test PCB on the PCB holder of the machine, 1st_calib_board can be used.

After the machine has been homed, use the manual control panel to move the nozzle above the center area of the PCB.

2. Manual Testing And Recording

Manually load a small nozzle tip (CN040/CN065/CN140/CN220) to the N1 (A-axis) nozzle holder.

Select Nozzle:N1 from the Machine Controls panel.

Adjust the appropriate distance option and gradually lower the height of the N1 nozzle until the nozzle tip just touches the surface of the PCB.

Record the Z height value in the current status bar (bottom right corner).

For example, the current Z position for N1 is -23.50

Click the P button on the Z-axis to return the Z-axis to Z=0 point.

3. Finish Machine Adjustment

Now we have obtained the default PCB surface Z height value。

For example, the current Default PCB Z height = -23.5.

Tip

In actual jobs, to provide additional downward pressure on parts, we can lower the placement height further by a certain amount (typically between -0.3mm and -0.6mm) from the Default PCB Z height.

For instance, based on the value above, we can set the Board/Panel's Z height to -24.0.

Manual unload the nozzle tip on the nozzle.

Note

Always keep the actual nozzle loading state consistent with the software state, otherwise it may result in a running error, or even a physical crash.

The machine adjustment is now complete.
