THIS MODULE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND

Chip

This module creates an array of position which is used as an iterator to move around a defined area.

The area is defined by a home point and an end point. once these coordinates have been set, calling the various functions will iterate over the whole area by chip.steps steps.

The module supports few algorithms which may be used by the user to discover areas of interests:

• hozizontal() scans the area from the home position to the end position by iterating over the X axis first

• vertical() scans the area from the home position to the end position by iterating over the Y axis first

• random() scans the area randomly

• spiral_inward() scans the area from the home position to the center in spiral

• spiral_outward() scans the area from the center in spiral

Example code

from glitch3d import chip

target = chip()

# origin
target.set_home(0,0)

# chip definition
target.set_end(250,250)

# steps
target.steps = 10

for position in target.horizontal():
    print(position)

A jupyter notebook is available to play around and visualize the chosen algorithm movements.

Printer

This module offers basic functions to drive a 3D Marlin compatible printer through USB (e.g. to perform FI attacks).

The master branch will be kept as generic as possible and has been tested on the following models successfully:

• Creality Ender3
• Creality 6 SE

Example code for CR-6 SE

from glitch3d import printer

# Define Serial port settings
serial_port = "/dev/ttyUSB0" # or set to None for automatic detection
serial_baud = 115200
serial_timeout = 1

# Establish connection with the printer
p = printer(port=serial_port,baudrate=serial_baud, timeout=serial_timeout)

# Load printer limits definitions from configuration file
p.load_settings("settings/cr6s.ini")

# Enter Manual mode
p.manual()

Manual mode

In Manual mode, the following keystrokes are supported:

• up Move probe forward / Y + step
• down Move probe forward / Y - step
• right Move probe right / X + step
• left Move probe left / X - step
• u Raise probe / Z + step
• d Lower probe / Z - step
• + Increase step (0.1,1,10,100)
• - Decrease step (100,10,1,0.1)
• s Manual step definition
• h Home on XY !!! WARNING printer dependant
• z Home on XYZ

For safety reasons, a small routine was added to raise the probe of 20.0 mm before homing.
