RepRap 3D printer making progress
Written by Walter on 21/1/2011
Time to post some videos of my latest 'hobby project' a 3D printer: First time we melt plastic ABS with our extruder: The first stepper is now tweaked/fine tuned to run smooth and fast with a pololu stepper and attiny2313 for testing.
This is doing 1000 step increments forward/backward (so verry high resolution and pretty decent speed.) Also when we switched the pololu to 1/16 steps it became really quiet in operation as well ;) Even more good news, just now a mail package arrived. It's my arduino mega clone I bought from ebay this sunday! Horrai my printer/robot is getting a decent atmega1280 brain now! UPDATE: finished Y and Z this friday night. Rounding up the stepper control now and found a smaller power suply in attic (from old broken laptop). No more stopping now, this thing is gonna print by the time my PLA 200meter roll arrives sometime next week ;) Z-AX running: Y-AX running the platform (EDIT: SORRY THE FACEBOOK VIDEOS ARE BROKEN)
