Re: 3D printed vacuum robot - 12 years ago

If you're going for a vacuuming bot, I think the first goal should probably be the vacuum itself. But you could go for a bot as a platform or as proof of concept about the navigation and then make the vacuum extension. (Or hope someone else pick it up) Wonder if scrap cloth or maybe loundry flufs(most consistent) could be used as filter material. Probably centrifugal separation is good too and a

Re: I printed weed-wacker line. - 12 years ago

Surely we can print an air-duct to your window to get rid of the fumes.. About heating it in the oven, might fumes come out at that point? Can it contaminate the oven, would the oven still be good for food? Any measures to take to improve that? @rsilvers, quite aside, but seems a bit strange to use a forum as a blog. (but whatever floats your boat)

Re: problem: not enough plastic extruded when accelerating - 12 years ago

I like that you're using such high speeds. I havent seen much about what 'standard' to use for machine speeds. Are you sure if it is actually not extruding enough? To me it seems more likely it is extruding enough, but the filament doesnt make the connection, and gets janked off? This kindah looks to me like something a slicer could do something about, by having a 'connection-speed' or minimum c

Re: I printed weed-wacker line. - 12 years ago

I was confused, i thought "that thing isnt a weed whacker".. Also, instead of screenshots, why dont you do file->export config and upload that file as attachment, that'd be much easier to handle! Pretty cool, 23$/3lb~23$/1.3kg ~17$/kg looks cheap to me. I suppose we dont know what material the factory produces exactly, some kind of nylon i suppose hence the drying of the filament. Did you ge

Re: Excellent print Mendel 90 - 12 years ago

Excellent prints. The grey stuff is printed right? How did you print it, the paneling was printed flat and bent, the chairs with support up to the bottom? (I dont know much about ABS printing, think it'll probably be quite a while till i try something else than PLA)

Re: Need help implementing PAUSE in Repetier Host/Firmware - 12 years ago

I dont have a good answer, but this might be a good time to bring up this idea; Why not have a standard serial/I2C interface with some standard way get info and send commands? This could include a 'pass-along' command for getting/sending data from the computer attached to the printer. Of course with accompanying arduino library, The idea would be to make experimenting with ideas like these easi

Re: Link some nice non-thingiverse designs - 12 years ago

Fabfabbers looks pretty damn good, i like adding with github, and you can infact add a subdirectory. I already added three of my models. I have a question, is it to share development or release versions? The build in suggest development. Maybe that is the proper way of going about sharing in the first place.

Re: Link some nice non-thingiverse designs - 12 years ago

I'll take a look at both, already have openscad and implicitcad installed (with workflow, i just have to push alt-v and it will start them with the file) and prefer doing things locally on my own laptop. (fabfabbers)I already have basically all my designs collected in one github repo. Which is more than twice what i released, but it aint all good . I suppose i should just look, i might answer m

Re: Playful Parenting Chalenge 2013: Water WALL - 12 years ago

Bit sorry this didnt work out(yet?), it is a good idea, there are plenty of things for toying with water flow we could print, floaters can open/close channels and stuff, maybe even using larger streams of water to pump up another stream, probably one-way valves. Thingiverse contains some flow based, spring based. Looks like they're potentially good for other things too. of mine is made for havi

Link some nice non-thingiverse designs - 12 years ago

Thingiverse often turns out to be the place where i search for designs of stuff, since physibleexchange is down, and thingtracker is still mostly a proposal. So do you know nice (printable)designs that arent on thingiverse? Also, any advice on searching for designs outside thingiverse, generally? I suggest putting the word 'physible' on designs somewhere, at least, that word doesnt occur much in

Re: STL file -> image file? - 12 years ago

Been writing a fancy script(its just bash, that part sucks a little... but it ends up working fine) to represent designs, where you basically just provide some files and it generates a page. I will probably publish it on github at some point.(It should support thingtracker) So i too want images from .stls, finding this using povray, i have a little experience in povray too was handy.

Re: 3D printed vacuum robot - 12 years ago

Sounds like a good project. Didnt find much about it, just this. Must...hold...back...speculation. (failed..) The idea is getting the robot to get everywhere at some point, preferably not redoing too much. So i think mapping and knowing the current location is the most important thing. I think it can be done with ultrasonic and distance tracking on the wheels, but the software for mapping and ID

Re: Kisslicer Hole Through Side/Strange paths.... - 12 years ago

You 'envision'? Be specific when asking things, what are you using to design stuff. Not that i can necessarily help. Stuff not slicing correctly is a pain in the butt. I try switching between implicitscad, openscad,(usually that doesnt take too much) using admesh, meshlab to try fix it, but it isnt fool proof.

Re: 220Volt heated bed? - 12 years ago

How do you control it and measure the temperature. Though this may save energy in the transformer.. This is enough volts and current to kill you, and since you apparently cant calculate this yourself, i dont think you should proceed. Go for the 12V heat beds.. As far as i calculate the answer is no, i get ~120W

Re: Repositioning Endstops (Reprap Air/Prusa's) - 12 years ago

I havent had much issue with the wires, to be honest. You just have to wire it once. But the idea of using hitting bed to calibrate it does sound like a good idea. But getting the same distance is easier said than done.. People have done calibration where it measures the orientation of the bed. Frankly though, bed leveling doesnt seem to be so much of an issue in the first place) 'reprap indus

Re: Speeds not changing - 12 years ago

Be specific, do you observe the machine to see the speeds not change, or do you inspect the gcode itself? I see slic3r has (optional)acceleration limitations, slic3r --help seems to imply --default-acceleration is 130mm/s^2 But when i run it without providing any settings and do --save it has default_acceleration=0 in it. The machine itself also has acceleration limits on it. At 130mm/s^2 it tak

Re: Scaling confusion too - 12 years ago

Maybe slic3r is just telling you how much room it will take in the bed, it adds skirts around the object. Looking at it, skirt_distance is defaultly 6mm, so a few skirts would get you at (24-10)/2 = 7mm on the outside of the skirts. Dont know what you mean with '15x15 on the platter'. Please be a little clearer in general mean in pronterface you look at it and compare with the grid?(1cm grid i t

Re: Scaling Trouble - 12 years ago

I dont think you should use slic3r to calibrate the machine,. (Though I think it is possible with scaling the .stl, setting temperatures differently, and using extrusion_multiplier). The idea is that the machine should 'know' the distance, temperatures etcetera instead of you indicating different values to compensate for the incorrectness of the machine. There are two processes here 1. The mode

Re: Scaling Trouble - 12 years ago

The simplest problem would be that the number of steps(of the stepper motors) per distance is wrong. This is set in the firmware.(preferably not slic3r) M503 tells stuff about settings, M92 is the one that defines the number of steps per some distance.(that could be any distance like motionof heads/bed but also motion of filament) Two ways to go about this, one is to print some object, say a 15x

How do you locally fix .stl files? *Much* prefer commandline approach. I have problems with dissappearances in slic3r.(with both outputs from openscad and implicitscad, the latter still seems superior to me) I dont want to put such problems in uploads. And they can probably be compressed a bunch too. Stuff like:meshlabserver -i file.stl -s ~/.meshlab.d/simp.mlx -o file.stl -om vc vn.. doesnt se

Re: Extruders and HotEnds everywhere ! - 12 years ago

The fan is to keep the cold part cold, so the melt doesnt crawl up and solidify higher up, jamming the printer. For me at least the cold end really is cold to the touch.(careful trying it tho) You also want to cool the extruded and layed down, when you have single thin high parts you can notice that it may drag the print around because it has sufficiently solidified yet. I think i actually saw
