Step 1

CHECK SYSTEM SETTINGS

First, connect your Buildini 3D Printer to your computer with the USB cable. Once connected, open Simplify3D® and navigate to the Tools menu. From the drop down, pick Machine Control Panel. Click the Connect button to connect to the Buildini 3D Printer.

Click on the Temperature panel and uncheck the Monitor Temperature check box. This will make the next step easier.

Click on the Communication panel and type M503 into the text box, then click send.

The Buildini will send core system settings in the communication box. Look for the line: Steps per unit: M92 X100.00 Y100.00 Z400.00 E140.00. Write down the X and Y stepper values:

X Stepper Value =
Y Stepper Value =

Step 2

PRINT CALIBRATION CUBE

Click here to download the calibration cube file. Slice it and print using your normal print settings. We recommend a 0.2mm layer height with 15% infill.

When finished, measure the cube with calipers in the X and Y dimensions. The cube should measure 20mm x 20mm x 20mm. Account for margin of error and take multiple measurements, averaging the result.

Using the values you have measured, calculate the new stepper values with this formula:

• X Stepper: (Old X Stepper Value * 20) / Measured X Size
• Y Stepper: (Old Y Stepper Value * 20) / Measured Y Size

Write down your new values:

New X Stepper Value =
New Y Stepper Value =

Step 3

ENTER NEW STEPPER SETTINGS

Reconnect the Buildini 3D Printer to your computer using the USB cable and open the Machine Control Panel in Simplify3D®.

In the communication panel, navigate down to the text box.

Enter the following command with your new values:

M92 X[New X Value] Y[New Y Value]

Click send. Then type M500 and click send to save the settings.

Print the test cube again. If dimensions are accurate, your stepper motors are tuned. If not, repeat the steps until satisfied.
