This blog is to document the development of my EMC based REPSTRAP based on the REPRAP project.
The project uses an MDF frame with comercial bearings and slides on all 3 axes and uses commercial stepper motors and drivers.
The axes are moved by rotating threaded rod with long connecting bolts to drive the plates. These work well and do not seem to have backlash.
The steppers are coupled to the rods using rubber pipe(petrol pipe) and jubilee clips.
The steppers are controled by the free EMClinux CNC programme, www.linuxcnc.org/ .
The extruder is the reprap extruder.
The .stl files are generated by the CoCreate modelling personal edition and then converted to G code by skeinforge.
