The saga of rebuilding and reconfiguring my old Thing-O-Matic around an Azteeg X3 controller and Marlin software at Squidwrench continues apace:
A major benefit of doing this at the group meetings has been showing everybody that 3D printing isn’t a mass-production process. The pile of calibration objects includes an inordinate number of those thinwall open boxes that take about five minutes each:
But it’s producing reasonable quality stuff again:
The loose threads on the outward sloping sides of that dodecahedron show that I forgot to lower the temperature after a bit of trouble with adhesion to the platform; the problem turned out to be an interaction between Slic3r’s minimum layer time and minimum printing speed settings that I didn’t notice.
A disadvantage of doing this at the group meetings is that two or three hours of tweaking and printing, once a week, draws the whole process out far longer than anyone else expected… [grin]
