Quick print for calibration of X-Axis, Y-Axis, and Z-Axis.  Three models are included, two 60 mm and one 30 mm.

Before using one of these prints you should first make sure your bed is trammed (leveled), your e-steps are calibrated, and your z-offset is adjusted to prevent elephant's foot.

Printing

Use either 0.16 mm, 0.2 mm, or 0.3mm layer height.
No supports.

Calibration

Instructions for Marlin…

After you have measured the X, Y, and Z values, you may need to recalibrate your printer.  The following identifies one method.

Connect your computer to your printer using the USB port.  Then using a program such as pronterface or octoprint send the “M503” command which will return a mess of information.  Look for the line that begins with “M92”.  This will include a set of numbers representing the current step values prefixed by either, X, Y, Z, or E.  Write down the numbers that you need to update.

Then find the new values by using the following formula:

lengthRequested / lengthMeasured * currentStepValue

As an example:  60 / 59.1 * 400

Update the printer to the new step value by using the “M92” command.

M92 X###.##
M92 Y###.##
M92 Z###.##

Then save the updated values to your printer:

M500

Change History

2024-04-29: Allow for better prints when using 0.6mm nozzle.

2023-02-11: Add another 60 mm model that prints even faster.

2023-02-04: Trimmed some more time from the print.  Make sure you print this model with no supports.

2023-02-03: major rework to reduce print time by almost half.  Now has two models, one that is 60 mm and one that is 30 mm.  Both can be used with either 0.16 mm or 0.2 mm or even 0.3 mm layer height.
