Re: UK component sources - 16 years ago
those parts look good. there were a couple mistakes though. the 10nF capacitor was a 1KV rated capacitor. we only need about 25 max. i found a 100v one that will work. the one you specified was overkill and also probably wouldnt fit the footprint. i know because i made the same mistake =) the sockets you found were milled ones... they will work, but the swiped ones are much easier to inserby ZachHoeken - Controllers
Re: McWire vs Darwin in Host software - 16 years ago
yeah, its definitely do-able. there are a ton of things that need to be done in the host software, the problem is that most of the team is focused on getting the actual printing perfected. not to mention most of us have jobs and work on RepRap in our spare time. anyone want to pay me to work on RepRap full time? i'll fix all the java host bugs =)by ZachHoeken - RepRap Host
Re: Location of Preference file in Host Software - 16 years ago
not yet. its one of the things that needs to be changed. basically, it looks for a file like ~/.reprap/reprap.properties which would be a global config file.by ZachHoeken - RepRap Host

awesome! i work at vimeo. fun to see a link to it not posted by me =)by ZachHoeken - General
Re: McWire vs Darwin in Host software - 16 years ago
or if you're using the Arduino electronics, insert the stepper motor plug backwards. works just the same.by ZachHoeken - RepRap Host
Re: Controlling stepper duty cycle in PIC boards - 16 years ago
i'm not 100% sure, but i think the 'power' setting in the exerciser controls it. i'm not sure which setting in the prefs controls it, but that should get you going in the right direction.by ZachHoeken - RepRap Host
Re: Arduino KiCad - 16 years ago
yeah, it uses eagle. the program is totally free if you just want to view schematics (or make 3"x4.5" boards.)by ZachHoeken - Controllers
Re: ZIFduino - 16 years ago
i could see how that would be useful, if you wanted to program multiple chips if you were selling a kit, or something of that nature. day to day, it doesnt make much sense, especially since arduinos are self-programming =)by ZachHoeken - Controllers
Re: Extruder Questions - 16 years ago
if you have the Arduino electronics, the connector will fit in backwards, no big deal. it's a keyed connector, but not as strong as to prevent you from putting it in backwards. reversing it simply reverses the direction of rotation. if you have the PIC electronics, it should have told you to wire it up specially.by ZachHoeken - Mechanics

Re: Arduino USB Possible? - 16 years ago
Hey Willow, The Arduino's are drop-in compatible (all of them!). We have a firmware for the Arduino that emluates the current PIC system 100%, including pausing problems. A group of people on the forums have created a GCode Interpreter firmware for the Arduino that uses GCode to send commands. with that, you can drastically reduce segment pausing. I have that working with the RepRap host soby ZachHoeken - Controllers
Re: i would like to trart building.... - 16 years ago
also, there is a parts list at that is setup to handle multiple suppliers. from there its easy to find the various suppliers for parts and how much they charge for each part.by ZachHoeken - Reprappers
Re: Steppers and obtaining them - 16 years ago
i wouldnt be too sure about that r2k. your average stepper motor suitable for a RepRap machine costs up to $30. the one we spec'ed out from Keling is $25. a commercial stepper driver will set you back at least $60, but more like $100. hell, even the stepper driver we provide still costs at least $30 in parts. its much easier to standardize on a controller, then find motors that are suited foby ZachHoeken - Controllers
Re: Mirror (+backup) servers - 16 years ago
Hey Erik, Right now we're trying to transition to dedicated server someone donated to us. Unfortunately nobody really has the time to manage that sort of thing (we're all too busy working on our machines, heh.) If you're interested in helping us migrate our stuff to the new server, it would be very easy for you to setup your rsync stuff from there. if this is interesting to you, please let meby ZachHoeken - General
Re: RepRap counter - 16 years ago
thats a great idea! i added the DNS record. good luck with this, and i hope you come up with something cool. if you want to use subversion to store your code we have trunk/reprap/web setup for some of the other websites (like the part lister.) good luck, and keep us posted =)by ZachHoeken - Reprappers
Re: Voltage regulator in DC motor driver 1.1 - needed? - 16 years ago
yeah, originally the 1.0 used 5V from the power supply. adrian made me add the regulator. he's got crazy plans to take over the world and that includes running all the electronics off one 12V power supply. think car battery or solar. the component is only like $0.10 and does add some nifty features like triffid pointed out.by ZachHoeken - Controllers

Re: Strange Stepper Exerciser Behavior with McWire, and some McWire Comments - 16 years ago
hmm... its definitely some sort of firmware issue. the electronics are essentially blind to what type of system they're driving. to them its just steppers, switches, heaters, and sensors.by ZachHoeken - Controllers
Re: JDM hardware help - 16 years ago
i second what forrest says. use arduino. although, technically we dont really recommend a JDM programmer anymore. there are pages on it in the wiki, but they should be updated.by ZachHoeken - General

Re: G2 and G3 (arc) codes for G-code interpreter - 16 years ago
good news! i added this update to the subversion copy. i'll be making a new arduino firmware release soon which will include it. thanks for the hard work. ps. if you want subversion access, just PM me your sourceforge ID and i'll add you.by ZachHoeken - RepRap Host
Re: Why a Type K thermocouple? - 16 years ago
the board isnt a part of any sort of 'recommended' reprap electronics right now. i was looking into thermocouples, found a simple circuit, and made a board so that people can easily start building and researching reprap machines using thermocouples. nobody is limiting anyone here. before, no thermocouples were supported, and today you can easily use a type K thermocouple. type K is the most cby ZachHoeken - Controllers

Re: Arduino / Bresenham linear interpolation with ramping - 16 years ago
nition: this is actually really easy, but we just havent implemented it with the arduino (yet). the arduino is capable of driving all 3 steppers to draw a direct line. please look through our arduino code for how we do this (look at the GCode_Interpreter code) Its very simple: we calculate the deltas, then set all counters to an initial value. we then add all the deltas to the counter, andby ZachHoeken - RepRap Host
Re: Question about stepper drivers v1.1... - 17 years ago
sorry guys. Pin closest to board edge is +5v, middle is signal, farthest is GND. I updated the wiki as well.by ZachHoeken - Controllers
Re: Having an intermediate file between slicing and building - 17 years ago

Re: G2 and G3 (arc) codes for G-code interpreter - 17 years ago
nice! i'll test it and try to integrate it with the subversion GCode stuff. great work. this should definitely go into v1.3 of the arduino firmware (which will be released soon.)by ZachHoeken - RepRap Host
