Mr. Plow: automating 3d printing of PPE shield visors for #OpShieldsUp, using JG Aurora A5

I’m trying to support masksfordocs (https://twitter.com/MasksForDocs), but only printing these 3dverkstan visors just 1, 2, or 3 at a time means there is lots of printer downtime while sleeping, napping, and 2nd nap. I tried stacking, but I couldn’t maintain reasonable print quality which meant more post-processing in addition to just separating them. So, I used inspiration from Make Anything’s YouTube channel to bump prints off between jobs, so I never have to touch the shields. Now, the only downtime (minus a few minutes for cooldown) is when the spool runs out of filament…

I used 3 of the included stl file and snapped them on the front rail of my JG Aurora A5, but you may be able to get by with less or may need more. Placement is key if you only have a couple, but if you have a bunch of these, placement shouldn’t matter much…

The gcode I used between prints is below (I just used this as my end gcode, then copy and pasted the whole thing for 2, 5, 10, 50 prints, however many you want). Depending on your printer and setup, you will likely have to adjust this to suit your needs. I also have the bed starting to cool down with 2 layers to go (using prusaslicer 2.2 added in a gcode line “M140 S50” to start cooling the bed down before the print was done).
