3. Makelangelo 5 to HUGE upgrade

Makelangelo HUGE is 1366mm wide and 2m tall. Some assembly will be needed to convert M5 to HUGE. An M3 hex head screwdriver will be needed.

The firmware code in the robot's brain needs to be adjusted to compensate for the new size. The Windows version of the Makelangelo Software can make this change.

Some cables will need extensions for the HUGE size. These are included in the upgrade kit.

The assembled belt and counterweights need to be replaced with the belts for the HUGE.

There are two cables from the left side motor. A 4-wire stepper motor cable...

and a 3 wire limit switch cable.

Follow these wires back to the motherboard. Some people take a picture of how they are connected for reference.

Notice the 4 wire cable is connected to the left stepper driver with the blue wire on the left.

Notice the left limit switch cable is connected to the X- pin with the red wire on the left.

With power off, gently disconnect the traced wires.

Using an M4 alan key (hex key), undo the screws that hold the left and right sides together.

Add the extension bar and refasten the screws.

Use the provided screws in the HUGE kit to fasten the left side motor to the other end of the extension bar.

By default the M5 comes with 1m timing belt pre-assembled for ease of use. The upgrade kit comes with 2m belts.

Take careful note of the position of each belt in their connectors and match the fit for best performance (square drawings free of curvature).

Also note the disc on the top should be a snug fit with the long side of the hole touching the belt.

By default all Makelangelos are tested as 5s. The latest edition of Makelangelo Software for Windows only includes an upgrade tool. It is located under File > Update firmware

In avrDude path, click the '...' and surf to C:\Program Files\Makelangelo\App

In *.hex file, do the same thing and then click on firmware-huge.hex

Connect the USB cable to the robot on the left side of the motherboard. Turn on power. Click the turning arrow button to the right of "port". A COM port should appear in the dropdown box.

Press Start. The application should take about 20 seconds to upload the firmware.

After successful upload the LCD panel will probably say there is an EEPROM change. Accept the change.

Confirm the change has been applied. Click the dial, navigate to Configuration > Advanced Settings, and verify that Draw Min X is -683, Draw MinY is -1000, and Belt length is 2035.
