Re: Why do these gaps appear in this sliced model? - 12 years ago

Ok so bit of a weird thing going on here then. I'll see if slightly changing the dimensions of my model will eliminate the problem. Thanks again for testing Chris!!

Re: Why do these gaps appear in this sliced model? - 12 years ago

So you don't get the gaps displayed in the pictures of the first post Chris? Then it must be something with Skeinforge on my system.

Re: Why do these gaps appear in this sliced model? - 12 years ago

Meanwhile I've hit google to search for a method for repairing stl's and have used "netfabb cloud service" to repair my stl's. I've attached the fixed file by Netfabb, but the gaps still show up after slicing .

Re: Why do these gaps appear in this sliced model? - 12 years ago

Hi Chris, So they're not solid . Scratching my head now about what to do about it since inside Sketchup the model proves solid. Can it get non-manifold in the process of converting it to STL? I'm sorry if I'm asking these things in the wrong place. Just wondering if someone maybe recognizes this problem. But thank you very much for checking my stl's, because I know where the problem lies!

Re: Why do these gaps appear in this sliced model? - 12 years ago

Thanks guys, The gaps do show up in the print so it isn't just an artefact. The strange thing is that when I slice only one segment or block of the "dodecagonal" model the gaps don't turn up in the block (photo attached). As soon as I add another segment the problem shows. I guess maybe it has something to do with the orientation (different angle ) of the blocks which causes problems for Skeinfo

Why do these gaps appear in this sliced model? - 12 years ago

Hi all, I sliced the attached model with the PLA 0.2 profile with Skeinforge and was wondering why the gaps (marked in the pictures) appear in the sliced model? Can I do something with the settings to get rid of them? They don't show up when the model is sliced with the PLA 0.3 profile. Much thanks in advance, Niels

Re: How would you slice this stl? - 12 years ago

Hi numbersix, I totally forgot to reply to your above message. Meanwhile I figured it is indeed due to vibrational ripples. I'm printing with feed and flowrate at 60. The arcs used in Sketchup were divided into 96 segments. I also changed the design a bit but I would love to see how the part turns out on your printer so I'll mail you the stl. That is of course if you're still interested in doin

Awesome people in this community, respect!

Thanks Setherith. Those programmer(s) of Skeinforge certainly knew how to throw in a lot of cool features in one program

Ok thank you guys! I'll try the different methods and compare them.

What is a reliable way to calculate cost of filament usage per part? - 12 years ago

Hi all, I was wondering what would be a good way to calculate the cost of filament usage for a certain printed part. Can you just weigh the part on a scale and derive the cost from the weight and cost of the full reel (given the weight mentioned on the suppliers website is accurate)? Or does some weight of the filament get lost during printing (fumes etc)? Thanks in advance, Niles

Looking slick Muelli! Lights on the carriage would indeed be very cool. Very curious about that one. I saw you have a Pi-cam installed? Can you get a good view of the print with the fan installed?

Re: Squealing/squeaking and Ticking from Right Hand Z Threaded Rod - 12 years ago

Ok thanks Garry, I'll try that as soon as possible. I think that after seating the nut, you have to recalibrate the printer?

Hi Garry, That's great! How do you re-seat the brass nut?

Re: Squealing/squeaking and Ticking from Right Hand Z Threaded Rod - 12 years ago

Makes sense indeed, so no amount of oil will ever fix that then.

Re: Squealing/squeaking and Ticking from Right Hand Z Threaded Rod - 12 years ago

Hi Garry, Yep, experiencing a high pitched squeak/squeal coming from the right z axes here too. Indeed only when it's moving downward. Had this since the beginning even though sufficiently oiled. Seems to be a little less after oiling but soon returns. I decided not to worry about it but the idea that this maybe due to some high friction or something isn't too soothing I must admit. Can't say I'

Re: How would you slice this stl? - 12 years ago

Hmm.. I was just thinking about curved surfaces in Sketchup not being being true curves but more a connection of linear segments which are displayed like a smooth surface. Maybe the segments show up in the print again. The pattern in the picture is more pronounced at the far ends of the object though...

Re: How would you slice this stl? - 12 years ago

Hi Richard, It was printed with a feedrate setting of 60 mm/s (flowrate the same) and the travel feedrate is set to 200 mm/s (standard setting in nopheads' PLA 0.2 profile). I believe that Chris has set the accelleration to 2000 in the firmware (instead of the former 4000). Now that you speak of ringing, I have attached a picture which maybe shows a further indication of this?

Re: How would you slice this stl? - 12 years ago

Hi Chris, Yes it's PLA. That trick you mentioned might work because the object sits on the inside of a shell with the same inner radius so I could use that as a former. But I think I like the way it came out. As you can see in the picture mendel90 can handle the job with the upright slice I had to bump the brightness of the picture to show some more details of the object since it's printed in b

Re: How would you slice this stl? - 12 years ago

Hi Neil Thanks. I should have mentioned that the rear surface is slightly curved. The curve has a radius of 6.5". I've sliced it upright in Skeinforge and although the print failed due to a lift from the bed, it managed to complete the holes which came out nice. Slicing it with the back surface flat should result in less support material though since the curve is pretty shallow, so I'll give tha

Re: How would you slice this stl? - 12 years ago

The support structure came out too dense (lines very close to eachother) and bonded too strong to the object with Skeinforge. Guess I have to lower the support flow rate ratio

How would you slice this stl? - 12 years ago

Hi all, I'm posting this picture of a design I need to print. As I'm very new to 3d printing I would greatly appreciate it if you have any tips for slicing this object. For instance on the orientation of the object. Is it best to print it upright like in the picture, with support material underneath the wide overhangs and the tubular sections? (I will try with both skeinforge and slic3r) Thanks

Ah ok,I forgot one. Thank you Chris.

Re: Which temperature and how to adjust it? - 12 years ago

I don't really understand what value has to be changed in the start.gcode file. I changed s185 to s210. Then the extruder heated up to that value but dropped to 185 again after. Seems to be printing perfectly at 185 C though with the red tape (even though it's rated 190-220)

by Nilez - Mendel90

Re: Another Happy Mendel90 Owner - 12 years ago

Yep it is set in .skeinforge\alterations\start.gcode.

Re: Still problems with small fills - 12 years ago

Re: Which temperature and how to adjust it? - 12 years ago

Hi Chris, sorry you had to state what was explained in the manual. I just read it at page 74. I assume that I change S185 to whatever temperature I want?
