Brother Glacius Posted November 3, 2022 Report Share Posted November 3, 2022 okay, so my jupiter is quite large and I have seen people create an inside heater. I'll have to see what I can find to replicate, otherwise its no printing until the summer. Or heating my garage up to 70 degrees. Quote Link to comment Share on other sites More sharing options...

Torg Posted November 3, 2022 Report Share Posted November 3, 2022 hmmm I am not sure about putting a heating device into the workings of a 3d printer. Does that radiate heat or is it for holding? A simple enclosure with a small heater is pretty effective. even a small tabletop grow tent could work. -d Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted November 3, 2022 Report Share Posted November 3, 2022 I watched a vid on it, it is a battery basically with a warming function. The Jupiter has a metal box enclosure already, so I think it will be fairly save to place that in a corner away from the vat where it can radiate some warmth.

Brother Glacius Posted December 14, 2022 Report Share Posted December 14, 2022 Woot! my FDM printer arrived yesterday. Got it hooked up and even did a test print. I think I need to calibrate again as there were some odd rough spots, but all in all, wow, so easy to get going. Now I gotta learn to load files and print an STL I own. 1 Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted December 28, 2022 Report Share Posted December 28, 2022 So I tried to do a FLM print on fast setting to see the difference in quality. What I got was an explosion of string. Is that a temperature thing? I have the printer in my basement so its probably in the mid 60's down there. The print area is enclosed but perhaps the speed was not giving the filament time to adhere? Just a curiosity thing really. I changed the print back to normal speed and it printed just fine. Quote Link to comment Share on other sites More sharing options...
Ish Posted December 28, 2022 Report Share Posted December 28, 2022 “Spaghetti-fication” seems to occur most often when the initial layers don’t stick to the build plate. Which probably happened because the plate was too cold due to ambient temperature… Quote Link to comment Share on other sites More sharing options...
scottshoemaker Posted December 28, 2022 Author Report Share Posted December 28, 2022 You may need to go into your slicer and look for something similar to "initial layer speed". In Cura 5.0 it's "Top/Bottom Speed". I run mine at 25mm/s Also assuming that your bed is heated, make sure it's heating to 50C-60C. Quote Link to comment Share on other sites More sharing options...
Ish Posted December 28, 2022 Report Share Posted December 28, 2022 Of course, sometimes the Machine-Spirit of the printer just gets grumpy. Remember to give it praise and thanks when it finishes a print job without error, for the Machine-Spirit is very praise driven. 1 Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted December 28, 2022 Report Share Posted December 28, 2022 It has a heated bed, and the printer does make sure its at temps before starting. Hmmmm, maybe the speed of printing aided in pulling the filament off of the bed despite it being hot. It was a curiosity anyways. I don't need to speed print. I'll try it some other time when its warmer. Thanks for the input. Still need to try my resin printer. 😔 Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted January 17, 2023 Report Share Posted January 17, 2023 so yesterday I tried to print an elephant on my J1 snapmaker flm printer. The first time was using cura and about a third of the way in, spaghetti happened with one of the legs...odd since that is a very thick part. So next I used their luban slicer and tried again...this time I could tell the supports at the bottom went bad right away....So finally I tried luban again, but I flipped the mode upsidedown first, thinking that maybe trying to do the legs with supports was too much....I also reinforced the area on the plate for extra adhesion...that seemed to work....but now the supports aren't coming off the model. I used the default settings from luban with a 50 degree angle. a few areas the supports popped right off, but due to the large area on the back...those are holding tight. How do I resolve this?

Torg Posted January 17, 2023 Report Share Posted January 17, 2023 Hmmm filament print stuck supports - I typically clip off the supports that won’t snap off with snippers. Leaving a little spot to clean up with an exacto knife and sand paper. I sliced my finger pretty good last month with the exacto knife lol. So I picked up a newer pair of snippers 🙂 Quote Link to comment Share on other sites More sharing options...
Ish Posted January 17, 2023 Report Share Posted January 17, 2023 It’s risky, but an scalpel heated with a lighter or a candle will slice through filament like butter. 1 Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted January 17, 2023 Report Share Posted January 17, 2023 that is the problem, the sheer number of supports on the back of the elephant is near solid...as they get further away, then there are gaps in the supports, not sure how I should have set it.

scottshoemaker Posted January 18, 2023 Author Report Share Posted January 18, 2023 Can we see a screen shot of the model? 1 Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted January 18, 2023 Report Share Posted January 18, 2023 I'll post one up later today. Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted January 19, 2023 Report Share Posted January 19, 2023 https://photos.app.goo.gl/imp9H5Qb4giWpW2J9 As you can see in the picture, there is about half a centimeter area touching the back of the elephant that is quite thick and then the supports thin out.

Torg Posted January 19, 2023 Report Share Posted January 19, 2023 ugh that sucks... do you have a band saw? sorry man that looks like a welded block of crud to cut through. But I think if you are trying to save this print ... then cutting then sanding and buffing are the only ways I can think of myself. -d Quote Link to comment Share on other sites More sharing options...
scottshoemaker Posted January 19, 2023 Author Report Share Posted January 19, 2023 It looks like there is some adaptive support density going on. If it were me, slice in Cura, print the model feet down, no raft, using tree supports. For standard supports, make sure the line count is 1, and use either Line or ZigZag support pattern. Grid is overkill. Quote Link to comment Share on other sites More sharing options...
Brother Glacius Posted January 19, 2023 Report Share Posted January 19, 2023 My first two attempts were feet down, but one of the legs went all spaghetti about a third of the way up, and then the other attempt, a front support came off the bed early on. I've got Cura and Luban as my slicers. I'll check the settings and go again with your suggestions. Learning is fun! 1 Quote Link to comment Share on other sites More sharing options...
Ish Posted January 19, 2023 Report Share Posted January 19, 2023 Remember, there are no failed prints. Only surprise bonus bitz for your future terrain projects! That tri-pod elephant? That’s a statue now. 1 Quote Link to comment Share on other sites More sharing options...
JamesIdle Posted January 20, 2023 Report Share Posted January 20, 2023 Tree supports would definitely solve the problem. I actually printed a very similar model a few years ago and ended up having to reprint with trees because of the support density. It worked like a charm. 1 Quote Link to comment Share on other sites More sharing options...
scottshoemaker Posted January 20, 2023 Author Report Share Posted January 20, 2023 Is the bed glass or magnetic sheet, or stock? Quote Link to comment Share on other sites More sharing options...
