#CncFoamCutter #HotWireCNC #GrblMega5X
This is a 4 part of series, it’s a long video so below are the timestamps to jump to the main sections.
The software section is the longest because this is the most challenging
00:00 Intro
00:55 Wiring the controller to the stepper motors
08:13 Checking the Axis work in the correct direction
11:32 Checking the Calibration
20:22 Hot Wire Temperature setting and testing
23:19 First Test Cut
31:53 Incorrect Wire Spead and Temperature Demo
32:39 Software to Generate the G-Code for a foam wing
It’s a full step by step build series from start to cutting your first wing.

It uses inexpensive 3d printer electronics and parts easily found in your local DIY store.
I use it to make RC wings and fuselages but it can be used to make many other foam projects.
Part 1 is the introduction give a brief overview of this step by step series to build your own CNC foam cutter
Part 2 is the electronics build and configuration
Part 3 is the mechanical build this video
Part 4 this video showing wiring, axis checks, calibration checks and making our first test cut. The last section shows software you can use to generate G-code for your wing
The free eBook also on includes detail on how to build the parallel port version, if you want to use Mach3 or Linux CNC
