Wow. impressive. What kind of budget is involved in this effort?by xiando - General
"If it's not that then I can't understand why it is it that using Slic3r 0.9.8 on my machine causes the print path within a slice to jump around from point to point like a caffiene addicted rabbit on speed, yet other users seem to be getting good clean results with this latest version?" idk.

Looks like a pretty cool gadget. I like the idea of using it as a repair tool. A variant could possibly also be used for applying z-axis banding to decrease delamination issues if it was compacted and suitably attached to a printer and appropriately driven.by xiando - General
Whoops...I guess I missed the part where the OP said he or she needed a MAC CAD program. Hmm...wait, the OP didn't say that.by xiando - 3D Design tools
Delamination is usually caused by poor layer to layer contact For instance, if you're not extruding enough material, it may never contact the lower layer properly to bond the two. Too much active surface cooling could do this as well, I think. fwiw, in general, it's nice to know the material you're printing with (ABS, PLA, etc.) the hot-end temperature, layer thickness, etc. in order to clarifyby xiando - General
Another thing that often helps with that problem is to machine or file flats into the shaft, and in some cases, to drill a shallow hole into the shaft in which the set screw (grub screw) beds itself (poor man's key). If using machined pulleys or gears, one can simply apply loctite to secure the screw.by xiando - General
Ah!@. that's one I missed. good call steve.by xiando - General
I cannot modify a file I cannot open. I can modify a file I can open, even if it isn't a perfect conversion. And at the very least, I can generate a print path using an stl file, source or not. Until there is a universal CAD system, (open source of course) which provides the same level of consistency and power that closed source CAD programs offer, your attitude just proves Idolcrasher's originaby xiando - General
No, I am not Akhlut. I am combating the perverse misuse of the open source paradigm by children who have a myopic viewpoint. As far as I know, STL is used by all or nearly all of the folks using these prusa-mendel-based (loosely speaking) printers. It is the sole format usable by all players. It is forward and backward compatible by the largest number of design and print programs, and thereforeby xiando - General
Adhesives tend to release in the presence of heat. For instance, a trick to removing dried masking tape is to heat it with a hair drier. I would think the same could be said for friction tape, although you can test that yourself. Presumably, this is for PLA printing, (ABS folks can always use a wash of acetone or a thin slurry of acetone and abs as an adhesion helper), so I suppose it's not as muby xiando - General
yes, that's what I meant. rod or bearing or intruded crud or alignment...any or all could cause the translation mechanism to stick, in either the bed (Y) or the extruder (X). So check 'em all.by xiando - General
Two possibilities come to mind: 1) missing steps. Check your ?X ?Y drivers to make sure they're not over or underdriven 2) binding in the bearings. check to ensure alignments are correct, smooth rods are undeformed, and sliding friction is low across the full translation.by xiando - General
I agree. However, if I had the cash I'd be inclined to purchase solidworks over other similar packages. For freeware, I would choose the defacto standards already in use. Namely Autocad 123, Open scad, and Sketchup.by xiando - 3D Design tools
Miso, And I would not discourage your provision of whatever literal source file you use during the design. I would encourage you to provide an stl as well, as primary content, so that those who do not have access to whichever source you use are still able to print and to import into their design software. The point is to provide access to the largest set of people, not to adhere to an overly restby xiando - General
"To me open source means open to everyone, not just open to those who can afford to access it." No offense, but that's a bit naive. Are you saying that to be open source, we have to provide a computer and training to anyone who wants to get into 3D printing? (No, I know you're not saying that, but it is a natural extension of what you just said) I'm not arguing that releasing only files openablby xiando - General
"also it takes twice as much force to go around a 90deg angle. I'm not sure why but i think it has to do because of the feedstock resistance to bending. perhaps a temp change may have an effect? i don't know." That makes sense. I'd also think that there would be direct contact by the filament with the tubing wall on almost and bend in the feed, so sliding friction is also an issue. "just for thby xiando - General

Again fair enough. (I thought you were serious and had no reason to dispute your claims...xiando shrugs) "I have simply been put off recently by the open source claims a few kit sellers have been throwing" Understood.by xiando - General

Idol, Fair enough, although I don't see how someone who doesn't already have a printer is going to be able to take advantage of those STL files. Anyone coming into the project for the first time will either have to purchase the plastic parts or get a friend(s) to print them. If someone presents an idea for a part (or parts) but fails to provide useful files, then one has two options. beg them unby xiando - General
What specific problem are you attempting to solve sanman? You don't say.by xiando - General
Idolcrasher, Technical forums were never meant to substitute for personal investment in education. They were meant to augment that educational investment by providing a place for those of us who did to field questions, bounce ideas, etc, but not to spell it out in minute detail to those who don't want to have to "pay their dues" but want the reward that comes from that investment. I'm in 100%by xiando - General
Open source at its core is about sharing ideas with a central premise that ideas are not something one should be able to own or control. That's it. You're confusing the term "well documented" with "open source".by xiando - General
Folger's ground coffee (32oz size) comes in plastic "tins" now, so that might be a good candidate. The only problem with the plastic canisters is that they don't have quite as much rigidity as a metal coffee can, although I suppose it'd be easy enough to print and apply some reinforcing brackets.by xiando - General
Polygon, Well, I was really talking about buckling stresses more than the inherent issues of 1.75 vs 3mm fiber and precision. But your points are well taken, especially with regards to hysteresis. I hadn't considered that. Thanks for responding.by xiando - General
Just had an academic thought... Wouldn't 3mm filament be better suited to use with a Bowden style extruder, due to its increased rigidity?by xiando - General
