Oh c'mon !!!! First Print!


Recommended Posts

Posted · Oh c'mon !!!! First Print!

First print, no tweaking, barely know what I'm doing.... C'mon that's not bad:

first print montage

Looks worse in the photos. Looks much better in the real world.

Meant to note that the underextrusion on the base was because I didn't "prime" the filament feed.

    I think I had the temp too low. There were some chunks missing on the back. I lower the default to 180 from 210.

    I printed some calibration cubes at 100%, 150% and 200%. Even at 2x they came out OK.

    180C is too cold for that color filament. Unless you slow to maybe 10mm/sec which will take hours to print that robot. Also if it accidentally goes below 170C Marlin doesn't let the extruder move.

    Printing slower will improve quality more than printing colder. 210 is already an excellent temp. But this quality that you show is good enough for me personally.

    Jonathon, that looks real good.

    Gr5, I picked 180 just because that is what I thought was the right temp for PLA. For some reason, I thought 210 was more appropriate for ABS.

    In general, I think pictures make the prints look worse than they are. When the robot was done, I really thought it looked nearly molded.

    No, 240-250 or more is typical for ABS.

    180 is definitely low for PLA - for most things you should be able to print quite nicely in the 210-230 range. For most things it doesn't make much difference, provided the plastic is liquid enough to flow sufficiently fast for the speed and layer height that you are printing.
