Re: Only one window when I run reprap-host - 16 years ago
you're welcome. Well I guess jonwise meant to place it in the named folder. That folder does not exist in the compiled version; only packed directly to reprap.jar So either you can try creating such folder that'd be "\reprap\gui\botConsole\rr-logo-url.png" inside the org folder you already have next to the reprap.jar or you can try place that file directly inside the reprap.jar that'd be "repraby sid - RepRap Host
Re: Only one window when I run reprap-host - 16 years ago
here you are. But that file is only necessary for the sourcecode afaik, it's not packed with any precompiled host yet. (not even packed in the jar at reprap.jar\org\reprap\gui\botConsole) 'sidby sid - RepRap Host
Re: Where to get extruder plastic parts from? - 16 years ago
there were several attemps using pinch rollers, I'm not aware that one worked properly. the very first extruder for example used rollers So you may want to check the approaches already made first. There are several blog and forum entries you may want to take a look at. 'sidby sid - General
Re: Any word on the electronic kits comming back instock at RRRF? - 16 years ago
Well I'm not Zach, who is the only one who knows for sure ... But I'm pretty sure the complete kit will be back in stock. maybe it's just because there is no arduino diecimila anymore, because the duemilanove was just released. Maybe somethings changed and one of the boards need revision. Or maybe he just ran out of parts; as I said, only Zach knows for sure. Afaik you can preorder out of stockby sid - Controllers
Re: Getting a little frustrated... - 16 years ago
I've read this issue before afair... there's something wrong with the limit switches.. either they are always on or always off (can't remember really) IIRC it was LEAV having this problem, maybe you'll find his issue using the search. sorry for not being able to tell exactly 'sid found it: just read on, maybe it's the same error you haveby sid - RepRap Host

The less important yet fascinating status update ... Got the caps today and yeah it woooorks (at least the psu that is) the damn controlpanel is NOT.

Re: My granule hopper concept. - 16 years ago
Some sort of safety clutch? like those: But what I'm wondering is, it looks quite similar to the one that has been tested a while ago. There was a problem with heat conduction up the screw clogging the entrance and stopping the flow. the link with the result So I think we need the screw to be made of ...hmmm duroplast?

Re: Stepper Motor - 16 years ago
QuoteThe voltage rating is the maximum voltage you can use with a chopper drive. It is simply determined by the winding insulation. You don't need to run them at that voltage unless you want to go extreamly fast. true nophead, but from what I know from ordinary higher voltage DC motors (let's say a 150V DC Fan) they won't even start moving with around 9V and anything near 12V makes them turn veryby sid - Controllers
Re: Friction Welding: An Idea Worth Sharing - 16 years ago
I think that's a good idea for fusing two large printed plastic parts into one huge one that we couldn't print in one piece. But this is not really a rapid process from what I've seen with commercial friction welders (that are working a little different though) I'd guess it'll take more than a while to actually print one of our cornerblocks for example using this method. But just tell us Lawrenby sid - Plastic Extruder Working Group
Re: Stepper Motor - 16 years ago
I may be wrong, but 170V DC ? Sorry, I don't think they will be very happy with just the 12V we can deliver with our stepper driver. Also they're rated with 2.2 Ampere when in serial mode, the driverchip is stable up to 2 Amps and even then it needs serious cooling! I'd take a step back and look elsewhere personally.

Re: Tool-head controller - 16 years ago
Hi Viktor, but we already have a toolchanger mechanism, don't we? (at least I do have on my old bfb moulded parts) True I don't have the toolhead bay for new heads; but I have the "slide in" clamp and a connector on the toolhead, similar to the one Adrian posted in his mendel preview Jul 16th 07. So, why start from scratch again... ? And you're right, a ZIF Dip Socket won't stand the amps, buby sid - Controllers
Re: RepRap Host & USB, and Eclipse/subsclipse - 16 years ago
Generally there's no need for eclipse for just printing with the host. Ecplipse is a java editor to write your own java programs... No need for something like that if you don't intend to write or modify on your own. that being said, as far as I know (because I don't have a sanguino) It's as easy to use as the arduino, just connect the usb plug to your pc; (first time only open the arduino softwby sid - RepRap Host
Re: Tool-head controller - 16 years ago
What about those zero force connectors (what's they called in english? we call them Nullkraft) we just have to think of a way to move the lever.. the lever can be cached and moved be the toolhead, in that case the connector (head side) should be springloaded, so that it's connected before the lever is catched, and is still connected if the lever is released again.

Re: NEMA 17's and the McWire. - 16 years ago
I doubt there's a NEMA17 that has nearly enough torque to move the darwin z-axis upwards without any help. Although I may be wrong with that, I'm unsure if that motor (high torque nema17) is much cheaper than the corresponding nema23. And further more I'm pretty sure it can not be salvaged from any printer Pay a penny more and salvage motors from old non working plotters not printers, than youby sid - Controllers

Re: Does The Host Program Require Kubuntu? - 16 years ago
wait what? You should have an option for "run Live DVD Mode" or ""test kubuntu" or something similar (cannot remember what it's called atm) that option will just run kubuntu without installing anything. That's what you are looking for. And no, you can of course install the reprap host to your current linux installation too.

Re: 3D printer beginner - 16 years ago
Does it need to be chrome plated; or do you want to have a chrome look (like chromed carparts p.e.) first case: afaik there is no way to actually chromeplate plastic at home. afaik no way at all. inbetween: What you can do is ask a carpaint service nearby. ask for metallisation, there are different ways and colours available. None of which is chrome actually, but that's exactly how "chromed" carby sid - Reprappers
Re: PWM and Stepper drivers - 16 years ago
Nope the pwm is connected to the arduino/sanguino but not to any other board this wiring diagram might help: (just replace the arduino with the sanguino; make sure to use the correct pinout since that might be different (I'm pretty sure it IS)) 'sidby sid - Controllers
Re: DVD Image - 16 years ago
Well ... ummm... Okay let's start from the beginning. I guess you burnt the dvd image file as DVD not as CD, right? (some older dvd image might fit on a cd if you have an oversized blank) Assuming that, you also marked "make dvd bootable" in your burning software didn't you?

Re: McMaster-Carr 3D Models - 16 years ago
