Paulo just let me know that the latest RepRap Magazine is out.
The feature also includes the long awaited visual build instruction that I promised…
Get it now, and while you are there, donate a few Euro for the great job that they are doing!
Never tell a hacker that something is impossible to do. This is the story of the RepRap Morgan, the journey towards personal rapid protoyping, and how dreams can be realized – by patience and a good dose of stubborn stupidity. It is also the cribnotes you need to fast-track builing your own Morgan
After replacing the noisy extruder (Morgan0 did a beautiful job here) Morgan01’s prints improved… A lot.
In the photo you see some calibration blocks, a 200mm high, 40mm diameter tube, printed spiral vase style in order to test the smoothness of the complete usable Z-movement, after adjusting the holding tension of the backlash spring. There were some strange artifacts in a large print I left to work overnight, which prompted this action
The Z backlash should be adjusted to the pint where the bed almost wants to drop down on its own when not powered. This allows a silky smooth movement, and is apparent in the consistency of the tube.
The piece of tape on the bowden tube was used for the extruder calibration. Did not take it off yet.
She is starting to look like something.
The upgrade went well, and the frame is as stable as I hoped for.
The z-axis drive mechanism is the next to get an overhaul. The treaded rod did not perform as well as could be expected, and some way to stabilize the build table is also on the table…
