The cutting thread is made with acoustic or electric guitar string (the former) number 10. In the vertical carriage, a M4 x 60 screw is placed with two nuts at its end where the hot wire rests. Electronics: It's a PC power supply to feed motors and hot wire, Arduino Uno with Grbl-XYUV firmware, and a CNC shield with four Pololu DRV8825 for motor control. Update 20/09/2018: For convenience of colleagues who cannot find 1/2" guides, three STL files are added for the horizontal carriage to use a 12mm diameter guide. (Their names end in ...rod 12.stl)
