PlotBot

2.5 axis CNC Pen plotter.

Inkscape

Plots begin as vector drawings in Inkscape.

Gcode

Using an extension, drawing is exported to Gcode.

GRBL Settings

These settings describe the physical limitations of the machine such as acceleration, amongst other system parameters. They are stored on the GRBL.

CNCjs

CNCjs is used to send Gcode one instruction set at a time to the GRBL software on the plotter's microcontroller.

Billet machining the z-axis stage for strength and lightweightness.

PlotBot

Grooving the z-axis rods to accept retaining rings that will hold them in place. Hardened, precision linear bearing rod required developing a lathe grinding attachment.

Rail replacement project. MGN12 found to offer substantially higher precision, performance over LM10UU style bearing systems.

PlotBot

Arduino CNC hat populated with stepper driver boards. Note the jumper pin sets offering 1/8th, 1/16th and 1/32nd increment microstepping.

PlotBot

G-Code example, generated by a vector path to G-Code inkscape extension called gcodetools. This code plots the name "Dr. Young".
