Re: [UK] £299 Full 3d printer reprap kits April 2011 - 15 years ago
If I had money, I'd be interested in the kit without electronics but with an extruder, being as I have an arduino, steppers, and motor controllers, that's pretty much all I'd need. T___T I just don't have money right now. (Saving every scrap I can so I can keep my car atm) O-o you wouldn't happen to know what you'd be pricing the kit without electronics but with an extruder would you?

Re: I've officially bought stuff. (to start making my own system) - 15 years ago
I've already got an FTDI cable myself, though I forgot to put it in the shopping list above. On the picoduino website, you can get the FTDI cable for $15 as well, works great, and will save the extra shipping from buying from multiple places. (it's $5 flat rate from that site if you are in continental us, no matter how much you buy. Pretty spiffy.) Thanks for the suggestions on the thermistors.by Caliber Mengsk - Reprappers
I've officially bought stuff. (to start making my own system) - 15 years ago
Well, I've taken the plunge I suppose. I've just finished purchasing the 4 stepper motors from pololu. I've already bought (and received) the stepper motors, and I'm working on trying to get an induction heating system going. As far as the rest, should be fairly cheap I would think. My goal is to create a system for around $200-250 USD, and at this point, I think I might make it. I'll have to doby Caliber Mengsk - Reprappers
Re: New person here! (and a few questions) - 15 years ago
Well, I already have some copper to try to make an induction coil, I just need the components. I may go out and about up to lowes tomorrow to see what could be useful for that. Now that I think about it, my Dad has a drill press I can use to bore out my own holes in stuff. Not quite a lathe or anything, but I think I should be able to find a 3mm steel rod or pipe to be the induction core, and theby Caliber Mengsk - General
Re: New person here! (and a few questions) - 15 years ago
I'm expecting some problems, but I'm also expecting most of them to be cheaper ones. It's not likely that all of the electronics would go bad, nor is it likely that every piece of metal will be slightly bent or anything of that sort. To expect everything to be broken at one point during the process is be a little over cautious. As far as the expense of the extruder system, after I have the steppby Caliber Mengsk - General

Re: New person here! (and a few questions) - 16 years ago
Thanks for the information and suggestions. I've been looking on ebay and found a pretty good deal. 8 motors with 200 steps (1.8degree step) and at least 25 oz/in (the link you guys gave says a minimum of 19.7, so this should be great.) and possibly up to 35 oz/in, though I'll stick to the minimum number for expectations. Best part, is it's cheap per part. $34 USD for all 8 including shipping. Thby Caliber Mengsk - General
What the heck is mnm? (in relation to stepper motors.) - 16 years ago
I understand it's a measurement, just like g/cm or oz/in, but I can't find anything on what mnm is, nor how to convert it to something like g/cm. Any help on this?by Caliber Mengsk - Controllers
Re: New person here! (and a few questions) - 16 years ago
@Pica: Unfortunately, I don't have the money to live with the philosophy of "throw money at it". Anyway, using the tutorial link in my last posts, you can actually set up a unipolar stepper motor with just two wires, making for 8 wires for all four stepper motors, Things like the temperature sensors go to analog inputs, and if the end stops are just tactile buttons, they can be on either the analby Caliber Mengsk - General
Re: New person here! (and a few questions) - 16 years ago
Well, I can get a complete arduino shipped for $15usd, and if I can use these stepper motors it would cost me $20usd for four of them shipped. That would just leave the endstop sensors (extremely cheap version just being a tactile push button for each axis XD) The other components to build a circuit from the tutorial on using stepper motors with the arduino will cost around $15 for all of the coby Caliber Mengsk - General
New person here! (and a few questions) - 16 years ago
Ok, so I'm new here. (... and this is going to be a very long post) I've been watching reprap for a while (I think a few years) and have just now decided to post some questions. I've recently been getting into electronics. I'm working with arduino a lot now (planning on making lighting kits for models that can have a bunch of blinking lights and fading in and out lights, etc) and I know that theby Caliber Mengsk - General
