its broke, needs a ramps+mega combo
original body came from a MYDIYCNC that was left on a beach.
now try the software side.
TODO
z stepper motor is broken - nema17 replacement need to install.- connect the dremel to the RAMPS board
- limit switch
- z-probe - repetier z-probing
software
there are usually several programs in the process.
- create the artwork (inkscape for 2D, XXX for 3D)
- generate the toolpath/gcode (pycam, ....)
- cnc controller, to send the gcode
cnc controller
got it working with grbl controller on windows
universal gcode sender
using the 1.0.8 release , its java based so works anywhere. tested on arch/linux
