Many microcontroller boards used for grbl and grblHAL use a CH340 chip to connect to the computer’s USB interface. Just recently (Dec 2024), several users of the CNC Foam cutter reported problems. These included The genuine Arduino Mega 2560 boards do not have this issue because they don’t use this chip. Most of the boards…
Here are some tips and tricks for DevWing Foam2, which generates 4-axis g-code for CNC Hot Wire Foam Cutters. I use these on all my projects. Using DevWing Foam 2 with GRBL Hotwire This is very easy and all you need to do is select the following options on the last page of creating a…
DXF2DAT A common question is How do I import my dxf wing design into something like DevWing Foam or one of the free g-code wing programs? First, I would ask yourself if you need to use a DXF file. I have rarely needed to do that. Several aerofoil data resources can be used for RC-model…
PDF plans One of the challenges with any CNC machine is generating g-code. Most foam board plans are PDFs, which need to be converted to g-code to send to a CNC machine. You can use this process for CNC routers, laser and needle cutters I used this process on my recently USB-converted CNC router to…
The parallel port has been discontinued on PCs for many years now. It was mainly used to connect a PC to a printer. Mach3 was designed to use this port to send step and direction pulses to the CNC controller and receive inputs such as limit switches. Mach3 is still popular in the CNC world,…
When starting out using a CNC Foam Cutter, you’ll soon find that designing a wing can be a bit of a challenge. DevWing Foam 2 may be just the software you are looking for. It’s incredibly capable but like any software, you need to put in the time to learn it. Hopefully, this post and…
So you’ve made some wings with your Hot Wire CNC Foam Cutter and wondered if you can make fuselages as well I’ve been on that journey too and now I can share my knowledge and experience. I purchased DevFus Foam a few years ago and now there is a second release. In my opinion, it’s…
Why use Linux CNC? I suppose the obvious answer is that LinuxCNC software is FREE to use being Open Source. This post shows how to get the OX CNC router from OpenBuilds to work with LinuxCNC and a TB6560 CNC controller. But this should work for most 3-axis CNC routers. I’ve used Mach3 for several years, and…
TB6560 4-axis spindle relay configuration with Mach3 or LinuxCNC is fairly straightforward. But it took me some time to figure out. So here’s how I got it to work. I wanted to be able to control my Katsu (Makita clone) router from Mach3 and LinuxCNC. The goal was that it would switch on…
Mach3 is the software that transforms a computer into a CNC machine controller. If you can’t get your machine to work, I hope this helps you. If it still doesn’t work, please contact me, and I’ll be happy to help. I get quite a few questions from all over the world. Before you start Mach3…
