Microsoft Excel Based Hotwire Cnc Cutter Build - Part 1

 
Published on Jan. 27, 2014

I was having this idea to build a simple XY hotwire cutter using Excel. Today I had some time and started putting up a code to spin the stepper motor using Excel and VBA. This code can handle full and half step rotations. My next step is to write a piece of code to convert a GCode to Excel and make them appeared in 2 columns as X and Y values. I am also hoping to use a simple XY chart to plot the shape of the GCODE on an Excel graph and then show a moving pointer to display the hotwire location graphically on the chart.
