Nozlo

G-code viewer for visualising feedrate, bandwidth, fan speed, and temperature.

Installation

Nozlo requires Python 3.7 and an OpenGL-compatible display driver.

python3 -m pip install -e git+https://github.com/ianmackinnon/nozlo#egg=nozlo

G-code viewer.

positional arguments:
  GCODE                 Path to G-code file.

optional arguments:

  --verbose, -v         Print verbose information for debugging.
  --quiet, -q           Suppress warnings.
  --version, -V         show program's version number and exit
  --no-cache, -C        Bypass model cache and previous settings.
  --channel {progress,feedrate,bandwidth,fan_speed,tool_temp,bed_temp}, -c {progress,feedrate,bandwidth,fan_speed,tool_temp,bed_temp}
                        Channel to display.
  --layer LAYER, -l LAYER
                        Layer number to display, from 0 to n-1, or `first` or
                        `last` to indicate the first layer containing the
                        model or last layer.
  --single, -s          Show only the single current layer.
  --explode, -x         Explode current layer progress along the Z-axis.
  --ortho, -o           Use orthographic projection.
  --aim AIM AIM AIM, -a AIM AIM AIM
                        Aim coordinates for the camera.
  --yaw YAW, -Y YAW     Camera yaw in degrees, starting in positive X and
                        moving clockwise (looking down) around the aim point.
  --pitch PITCH, -P PITCH
                        Camera pitch in degrees, positive puts the camera
                        above the aim point.
  --dist DIST, -D DIST  Camera distance in mm for perspective view. Camera
                        frame in mm for orthographic view
