Re: RepRap near future - 17 years ago
well not exactly split electronics from mechanics (just like in the current how2) then create a simple mask. just as simple as you did with the gcode php case "sanguino": $tron = "sanguino.php"; break; case "arduino": $tron = "arduino.php"; break; and so forth the same with the mechanics case "printed or moulded darwin": $mech = "darwin.php"; break; case "lasercut bitsfrombytes": $mech = "bfb.pby sid - General
Re: RepRap near future - 17 years ago
It's not too easy to follow all the different pages and sites. Everything is linked crosslinked and linked back again, so most of the time trying to follow the "make your own" instructions your about to click a link and then another one and then back again. it requires six clicks to get to here for example. I know you cannot add every sublink to the main menu, and I am aware of the fact thatby sid - General
Re: Another first drawing, and another pen holder - 17 years ago
The extuder isn't too wide to mount them close together so especially for the smaller parts that may work very good (that is if the software can handle multi-item-layouts for multi-head-printing ) but I guess if two parts fit on one bed next to each other one can print two parts with two heads (a matter of positioning the heads manually to do it right i guess) But yes it's hard to make sure thatby sid - Reprappers
Re: Filament - 17 years ago
Forrest, as far as I understand Viktor with QuoteAnother crazy idea - maybe it would be helpfull, when we squeeze the roundish filament in a square shape? Easier to feed, measure and align? he doesn't mean actually square filament but some square tubing to feed the round filament through. That does make sense at least sometimes If your filament becomes oval it will turn inside the square tubingby sid - Reprappers

Re: Another first drawing, and another pen holder - 17 years ago
If you have one extruder, you can build another, no? that's why it's a reprap *gg* 'sid One should try to have two extruders mounted onto ONE darwin, most parts are multiple items, so one could print two indentical items in exactly the same time (if both extruders are identical) that'd be a good thingby sid - Reprappers
Re: Request: Control via Internet - 17 years ago
1. Nope dangerous state: self controlling system prevents itself from danger (heat, headcrash, and so on) lost session: depends on software; just like you can kick your last ftp session with just adding ! in front of your username... one can implement something similar. That is as long as the software runs okay, and the webserver itself is up and running. redundant systems for power, webserver aby sid - Controllers
Re: Filament - 17 years ago
Rollerways: two ball bearings, one fixed one "clamping" the clamping mounted an an arm that is connected to a poti. pro: easy to do cons: measures only one point and looses any ovalness (is that the right word?) accuracy depends on the poti maybe smaller changes are not even measurable (oh dear, is that right?...

Re: Request: Control via Internet - 17 years ago
most of that is pretty much useless. shipping fabbed object around the globe (especially to the poor countries you talked about) is the biggest part on the bill. They'd pay less for making stuff on their own. Do you have an idea of what is needed to control TWO robotic arms via internet? (two because of two probes on the multimeter that have to be moved independently) I'm sorry... but your talkby sid - Controllers
Re: Mimimum System Requirements? - 17 years ago
I disagree, It's some years ago that I had to run 3dsmax (4.2 it was afair) on that epia machine I was talking about earlier. And it was pretty fast (for that tiny little apparatus) okay, full featured (multiple lights, reflection, refraction a.s.o) renderings were close to geological time, but who needs such renderings for a printout?

Re: Possible cheep laser cutting service? - 17 years ago
1.5kg would be very close to one day (22,x hours nonstop printing at highest speed) so let's say one and a half (who needs sleep?) when printed on a stratasys machine. So it IS possible! I do think they use one of the nordson gunheads for hotmelt 'sidby sid - Reprappers

Re: Mimimum System Requirements? - 17 years ago
Well, if we stay with that java s* (almost said a bad word, I'm sorry) we have to make sure to use a System that meets the jre requirements. But if we change to a much simpler Software (like let's say replicatorG) we can use a less powerfull system. Ther was this guy claiming he'd controlled servos (or steppers? cannot remember) with some pda. That would be the perfect system for us. Small, poweby sid - RepRap Host
Re: Possible cheep laser cutting service? - 17 years ago
true! If you succeed with the selfmilled steppers it'd be a huuuuuge step forward. On the other hand I got myself some neodym magnets the other day... boy, they're expensive! I think with those it's almost cheaper to buy a stepper than to buy the magnets to build one myself Nevermind. To be honest I don't care much of the pcb milling, at least not because of the pcbs used for the reprap, as Iby sid - Reprappers
Re: Another first drawing, and another pen holder - 17 years ago
I stumbled upon some hotmelt glue guns (nordson) recently those were used to glue cigarette boxes and such, they are pretty fast have a needle valve inside and weigh about 700g so not too heavy (but surely too expensive) especially because it's not done with the gun alone ($400) you'll need a heated hose ($250) and the meltpot with pump ($3000) But we should take a close look at how they work, mby sid - Reprappers

Re: an idea: another extruder barrel heater - 17 years ago

Re: an idea: another extruder barrel heater - 17 years ago
fire them up, not set them ON fire think of about 200mA for a triac. that is about 2.4 Watts (compared to the 18 Watts with the original heater) do you think you can melt plastic with 2 Watts? maybe polymorph... maybe not 'sidby sid - Mechanics

Re: Official way to qualify as a "RepStrap" - 17 years ago
Well a repstrap is to make the parts for a reprap, later that millenium a mendel, but for now a darwin And if it can make a darwin, it can make almost everything that is not larger than the largest part of the darwin, not? (and some parts that are) If it can do more than that like hydraraptor is capable of some serious milling, and it appears your tommelise, too that's truely a benefit, but nby sid - Reprappers

I doubt that every homebrew cnc-mill can replicate it's structural parts.
