Segmented aprons work with ABS
I was lazy. I didn't even bother regenerating the gcode for x-carriage-lower_1off using ABS assumptions instead of HDPE assumptions. The first time I ran it just after resetting the Rapman 3 for ABS I didn't get the extruder orifice close enough to the print surface and the raft peeled away after a while.
I reset the z-axis and got it right the second time. Hint: The first level of raft extrusions have to be 2 mm wide or it will peel.
I'm too tired to do anything more than wait for this print to finish. I'll finish the blog entry in the morning.
Okay, so I wasn't too tired. HDPE on the left, ABS on the right.
The point is, however, that segmented aprons pretty much completely suppress warping in the Mendel x-carriage-lower_1off part. Using ABS gives you much finer detail than HDPE does for a 0.5 mm orifice.
