What’s in this eBook 6.0

  • This e-book is accompanied by the new software and firmware I released in Nov 2023. The Windows software is now called Grbl Hotwire using XYZA axes letters
  • Full instructions showing how to build the machine
  • An updated mechanical design from my original. I’ve made several modifications to make the build simpler. The new design is lighter and intended to be run with stepper motors and controllers used in 3d printers. You can still use other stepper motors and controllers if you wish.
  • Links to the plans for the mechanical build. Full-size templates for all but 2 parts of the build. There is a small charge for the plans.
  • Electronic installation and configuration
  • How to use the Arduino Mega 2560 with a RAMP 1.4 board including the MKS Gen L V1.0 and V2.1 (Comined Arudino Mega 2560 and RAMPS is one board)
  • How to use newer 32-bit boards running grblHAL
  • Using Marlin 3d Printer Firmware instead of a PC.
  • Part list required to build the machine. If you’re unsure then just drop me an email with the parts you are considering and I’ll take a look for you.
  • Foams and Hot Wires. Calculating the Kerf Value.
  • G-code Generation update with several software options
  • I’ve removed the section for using the old parallel port interface in this eBook. Details can still be found on the website.
  • Tips for builders in the USA where some metric parts are not economically available and with inch equivalents that can be used.
