fine by me! thanks for the hosting =)by ZachHoeken - RepRap Host
will do. i didnt do color this time, but i can do color next time. reprap green?by ZachHoeken - Plastic Extruder Working Group
i've ordered 100lbs of ABS and it will be up on the RRRF store in a couple days.by ZachHoeken - Plastic Extruder Working Group
hmm. make sure you copy all the files in /library in v1.3 over to the arduino library folder. things have changed and you need the new files.by ZachHoeken - Controllers
unfortunately for us, the gcode stuff is about 13K / 14K max on the arduino. adding more features is going to become a tricky game. this is why the next step in the long term is to finish the host modifications to support multiple reprap 'drivers' and then start work on the SNAP_V2 firmware. we can then move all the heavy lifting off to the host and be free to do lots of advanced things. thisby ZachHoeken - Controllers
hey, sorry about delaying so much. the latest version of the arduino firmware will use M106/M107 to turn fan on/off. expect it this weekend (or tomorrow)by ZachHoeken - EMC2
if you're not comfortable with hacking around in the code, i'd recommend using the latest version of the firmware/software from sourceforge. the subversion stuff is usually stable, but not always.by ZachHoeken - RepRap Host
sorry about not getting this back into the BOM. i've been busy lately, but i have a big weekend ahead of me, so hopefully i'll be able to do it while i'm attempting prints =)by ZachHoeken - Controllers
yikes! i'll look into this bug this weekend. i plan on releasing a new version of the arduino firmware, so i'll get these code upgrades into it as well. thanks guys!by ZachHoeken - Controllers
Hey Peter, Sorry about the confusion. We've transitioned from the 1st generation electronics to the 2nd generation (based on arduino). The RRRF sells raw pcbs for all the new (and old) boards. We are also starting to sell kits of the latest boards. Very soon, we'll be selling a single kit that contains all the electronics for all the boards you need to build an arduino. Stay tuned. In the mby ZachHoeken - Controllers
the arduino gcode calls extruder_manage_temperature() after every dda_step, so yes it will keep temperature controlled during a move =)by ZachHoeken - RepRap Host
i'm not sure. if you dig into the code, its at the beginning of the print sequence. it should be easy to turn it off and recompile.by ZachHoeken - RepRap Host
Hey Guys, I understand where you're coming from, however pretty much all of the boards are autorouted. I'll attempt the autorouting with single sided first, but it doesn't always work. Making single sided boards isn't 'my itch to scratch' so to speak, so I dont worry about it. If you want a single sided board, the files are all up on sourceforge or subversion for you to work with. If you comby ZachHoeken - Controllers
good catch. i'll remove that error. if you want access to the wiki, pm me for details. we've been having problems with spammers =)by ZachHoeken - Controllers
i believe that the motor should turn clockwise if you wire them correctly. however, if you're using the arduino system, its as simple as reversing the connector to have the motor rotate in the opposite direction.by ZachHoeken - Controllers
Hey Ian, The thermocouple sensor is an 'experimental' board that is not required. Its a very small (read: cheap) board, and I include it as a convenience for those who might want to experiment with it at some point in time. Cheers, Zachby ZachHoeken - Controllers
ian, always use the latest version of the arduino firmware. the single_arduino_snap is the recommended one to use. i'll be releasing a new version this weekend with some minor fixes, but its certainly usable.by ZachHoeken - RepRap Host
what are you trying to print? my guess is that this is an object with lots of round corners? if so, the problem is that there is no segment queue or anything, and its pausing between all the tiny little segments that make up the circle. there are some options to fix this, but i'm not sure of them off the top of my head.by ZachHoeken - RepRap Host
our stepper motor driver boards are rated for a max of 2A, so those motors you have will be sucking a lot more current than we can provide. a hack to get around it is to use a resistor to bring that current down. a cheap, low-impedence resistor that people often use is a small lightbulb, such as an automotive light.by ZachHoeken - Controllers
hey fernando! no worries... i can be frugal at times. i held my horses, and researched a bit more. for the americans, here are the bulbs i ended up getting: uvc / germicidal: - $9.07/ea uvb / BLB: - $5.42 / ea unfortunately, they dont sell fixtures in the store. however, the bulbs are standard 15watt / T8 size. i'm going to go to the hardware store and purchase some of the T8 fixtures toby ZachHoeken - Plastic Extruder Working Group
updated and fixed! thanks for pointing that out, bob.by ZachHoeken - Controllers
the board already is 12v. the voltage regulator converts 12v => 5v for the signal-level voltage. the motor supply voltage uses the 12v directly. (or whatever voltage you supply to that pin.)by ZachHoeken - Controllers
no pins have changed, but the dual arduino setup has been dropped as unneccessary. now that i've gotten it all working and have experience, it would be nice to update it with the 'latest stuff'by ZachHoeken - Controllers
very nice!! it will take a bit of time to churn over that and verify stuff, but i'd love to get that integrated with the main spreadsheet. i'll have to add a bit of code to support the 'replacements' stuff, but thats fairly easy. pm me your google account and i can add you as an editor of the BOM so you can add your changes directly.by ZachHoeken - Controllers

fernando, what is the required UVC wattage output? i'm looking for uvc fixtures, and they are really expensive... can i get by with 5 watts? i'm looking at this model: i would really prefer not to have to wire up my own lamp. i can see that going badly. if that doesnt work, would this lamp suffice? how do i go about finding a ballast / base to use it with? i'd hate to be stuck with theby ZachHoeken - Plastic Extruder Working Group
sorry! i need to update those docs to reflect the changes in the arduino stuff in the past few months. basically, like others have pointed out, you only need 1 arduino to get up and running. the 2 arduino was a 'safety net' and it turns out you dont need them.by ZachHoeken - Controllers
thats called 'software backlash compensation' and its a good idea on sloppy systems. i doubt we can fit it onto the PIC stuff, but i imagine it would be fairly easy to add to the Arduino code.by ZachHoeken - Controllers
awesome! i'm glad you got it to work. the bresenham algo is pretty darn fast... its all ints.by ZachHoeken - RepRap Host
nope! no need to... the thermocouple outputs a linear value... meaning its super easy to convert the analog reading to a celsius value. theres more information on the doc page: here's the code: int raw = analogRead(0); int celsius = ( 5.0 * raw * 100.0) / 1024.0; the GCode firmware already supports this, and it would be fairly easy to add it to the SNAP v1 stuff. it will definitely beby ZachHoeken - RepRap Host
