So 25 hours into my print i realize i forgot to add supports…
That’s the worst, then you think:
“Maybe it will be ok”
until it starts to air-print and you get free falling plastic…
Yeah lol. Well that was main chasis 3. Its gonna do 2 more air print. Main chasis 4 only did 1 i can probably sand it down. All the other parts look good. But im probably gonna have to reprint main chasis 3. Oh well it happens right? Lol
You could cut those pieces off, then reprint that part if the model and weld or glue it together. That way you don’t waste filament.
Spice thats a great idea! Idk if i can make the cut that accurately thou
@Cristian_Martinez I would personally cut it flush with the face it’s extruded from, that way you have that face to guide you. For the model, just import the file into Blender and delete everything that isn’t that piece, then make a new face where it’s open.
Thanx!

Ouch! Yeah, the lack of support messed it up. Good luck with the cleanups and possibly partial reprints. If you position your parts a little closer to eachother, you will probably speed things up.
@NathanielStenzel you may be right. I think i spaced them out too far. I was afraid of stringing thou lol
I do not blame you for being concerned about that, but if there will be stringing then there will be stringing regardless of spacing. At least that is how I see it. It does not matter if one end is not attached to something. Besides, strings and zits are easy to clean off of prints.
If i cant get a partial print for the main chasis 3 part i may just reptint it. #4 should be ok with just some sanding (ill probably try to just melt the excess in place or stuff it with glue) but im gonna add supports to #1 & #2 which i gotta print when i get home
True that on the cleaning up
I had a post a little ways back about how I was playing with friction welding. I honestly do not know if you tried it or if it would work for you with that particular filament. I seem to have good luck with friction welding ABS. I never tried to resume a failed print at a point of failure. It seems worth while to figure it out for those larger parts. Good luck if you decide to do it. I have no idea what you are trying to print.
3D scanner lol
Yep, it’s happened to me a couple of times, fortunately not on prints that long. Ages ago it happened and there was only one part that needed supporting - a fairly simple straight bridge. Luckily it was right at the front of the print and I made a cardboard support to fit while it was printing, slotting it into place just as the first layer came across. Didn’t think it’d work but it did, well chuffed!
@Jon_Gritton thats a great idea! Unfortunately im not home to prevent the other 2 air prints that are gonna happen on the same part. But the other parts are printing fine so i didnt want to stop it
@Cristian_Martinez I hope someone is home to watch the printer. As someone who has experienced a thermistor failure, I cringe anytime I hear of people running long unattended prints. IMHO no print job is worth burning down your home
Lol. Yeah i hear that. My mom is home thou im sure she will hear the fire alarm. Its freaking annoying -_-
I heard the MK2S had some kind of protection against that? Like stop extruding. Shut off the heat. And blast both fans to cool down
@Jason_D found it!
