Not sure how this came about, to some extent. Benchy that is a bench and not a boat.. hmmm... I miss my benchy!!!!!
It's a challenge, why not! I really wanted this to come out nice, so it's slowed down for bridges, since it seems to be mainly a bridge test!
I had to print 3 of these to get an understanding of what it wanted from me. Slow the bridge and overhang, reduce the accel in that area, and let it melt plastic quickly for the rest. I would like to see even better bridges, but it is what it is!
In order to get better bridges this is what I had to do:
1: Get PA right for bridges!! This usually means MORE PA than typical for the rest of the print. If you are .02PA then .028-.032 seems to work
2: SLOW DOWN BRIDGES! Here I am at 80mms for bridges and overhangs!!! This is because bridges are being detected as overhangs in some places! 35K acceleration, 85mms, 5SCV (I use change at gcode to customize features for this model. 5SCV for overhangs and bridges, 60SCV the rest.
3: Are the bridges as good as they can be, no.. I need to practice more with them!
This is ABS, 255C, 600mms, 60K acceleration, 60 square corner, 55+mms3 flow, 0.4 tungsten carbide nozzle, chambered at 57C. Playing around, as usual.
