i went back to marlin and changed some of the lines to const bool X_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. this solved itby kenneth kneebone - RAMPS Electronics
i checked other people's treads and questions about this, my board is RAMPS 1.3, the firmware is marlin,and the endstops are makerbot mechanical endstops- there is an old thread about this - and my set up is now a copy of what they seem to have done, re checked the wiring and everything, it's like in their diagram, the printer connects ok,the extruder goes, but the thing is it keeps replying ' eby kenneth kneebone - RAMPS Electronics
i have an old 203watt xbox power supply because that seems to be what many people were using to power ramps electronics, and have read a bunch of people's tutorials or wiring diagrams but would like to check with you guys. this blog: has a wiring guide but seems to miss out which screw terminals go where,- or maybe he says to put them only in the 11amp terminals from this photo- there is no heby kenneth kneebone - RAMPS Electronics
ah,ok, thanks. i downloaded the github version,couldnt get it to run,so googled other peoples versions and found this guys one: it does seem to work,pronterface connects and can manually nudge the motors,but not print files for some reason.by kenneth kneebone - Next Wave Electronics Working Group
i wonder has anyone got a working build of teacup on windows that they would be willing to upload? ive got one mostly working,it would be cool to have a look at what works though.by kenneth kneebone - Next Wave Electronics Working Group
thanks Traumflug,pronterface works,now i just have to check the stepper motor wirings, are they the same as for other generations? is there a reference/diagram of how they wire up,or is it the standard reprap oneby kenneth kneebone - Next Wave Electronics Working Group
oh,ok, other thing i wondered was: replicatorG and repsnapper still think its not connected, will it connect without the opto endstops and all pololus connected to it?by kenneth kneebone - Next Wave Electronics Working Group
this is odd,but on the one i downloaded,changed as per Traumflug's instructions,and posted,it says: #elif MOTHERBOARD == 1 #ifndef __AVR_ATmega644__ #error Oops! Make sure you have 'Sanguino' selected from the 'Tools -> Boards' menu. #endif ........and compiles without errors, but if changed to: #elif MOTHERBOARD == 1 #if defined __AVR_ATmega644__ || defined __AVR_ATmega644P__ #error Oopsby kenneth kneebone - Next Wave Electronics Working Group
Finch, i got the same error when i tried to compile that , did you use fiveD? but then itried this other version of fiveD,seems to compile but i still dont know if its fully right.by kenneth kneebone - Next Wave Electronics Working Group
thanks Traumflug,the test firmware is working fine, then i think i got teacup firmware uploaded with no problems, but i still cant get repsnapper,replicatorG to reconnize the board is connected.the baud rate should be 19200 right? it seems to be just the software not recognizing it,i looked around and a few other people had come to this similar block have i missed something really obvious? thankby kenneth kneebone - Next Wave Electronics Working Group
so, i saw you put stories of people who successfully used gen7 on your gen7 page,do you know what software/firmware they used? and can each be combined as you like? also but you can upload the firmware straight from arduino software, then it stays on the bord,right? *then* you can shut arduino and load reprap host,or replicatorg,right? thanksby kenneth kneebone - Next Wave Electronics Working Group
its the same adapter this guy had: and on that thread it was wired to something else,but mine /should/ be ok if its wired: GND--GND +5V--+5V TXD--TXD RXD--RXD RST--RST 3.3V empty empty CTS the board is soldered from a board i bought off you ,is there a chance the usb port on the computer is somehow putting out MORE power? can it do that? i tried using a different computer too. i put the jumpby kenneth kneebone - Next Wave Electronics Working Group
should the atmega get hot? i checked all the voltages before like in your diagram and they are ok. just when uploading it gets hot,maybe i have wired the usb ttl adapter wrong? this adapter has pins marked: 3.3v, RST TXD RXD GND +5V i connected gnd to gnd, left out cts and all the rest to their corresponding pins but it wont upload the test Firmware ... any ideas? thanksby kenneth kneebone - Next Wave Electronics Working Group
ok thanks,i tried changing from com1 to com8,but get the same message. does this mean i have somehow damaged the chip?by kenneth kneebone - Next Wave Electronics Working Group
thankyou very much Traumflug, that DID work. as far as windows is concerned,now i only have to figure out how ive got the wiring wrong :/ it says: C:\Documents and Settings\Home\Desktop\arduino-0022\hardware\tools>avrdude -C av rdude.conf -c usbasp -p atmega644 -P COM1 \ found 2 busses avrdude: error: programm enable: target doesn't answer. 1 avrdude: initialization failed, rc=-1by kenneth kneebone - Next Wave Electronics Working Group
does anyone have a simple guide for the avr programming bit? i tried this one avr tutorial but cant see how this and the instructions on the gen7 tutorial go together. its all typed in the command line right? but not quite as is? sorry to bother you lot with a stupid question, i couldnt find a tutorial that i could make sense of related to this thanksby kenneth kneebone - Next Wave Electronics Working Group
another stupid question,or an amateurish one anyway,how do you do the bootloader programming sequence on windows? ..... or,for that matter,at all? i looked for tutorials on it,any examples of what any of you did for this step? thanksby kenneth kneebone - Next Wave Electronics Working Group
that sounds good, how do we order some?by kenneth kneebone - For Sale
thankyou Traumflug, so would this work for the small atmega on an arduino,connected to the 644 one on the gen7 board? another question i had was whether a ttl to usb adapter would work,rather than a full cable,as the pins are slightly different?by kenneth kneebone - Next Wave Electronics Working Group
sorry if this is a stupid question,but: if you have a blank ATmega, and no programmer, can you use an ordinary arduino to upload to it? what wires would you use? thanksby kenneth kneebone - Next Wave Electronics Working Group
ok this thread seemed useful, thanksby kenneth kneebone - Firmware - mainstream and related support
oh also the readme file included ,but the folder for libraries in arduino 0018 is arduino-0018/libraries instead of arduino-00xx/hardware/libraries, maybe this is the problem? in the bit of gcode interpreter.pde where it says: //our command string #define COMMAND_SIZE 128 char word; byte serial_count; int no_data = 0; arduino gives an error, saying 'char word[128]' redeclared as different kind oby kenneth kneebone - Firmware - mainstream and related support
thankyou guys for helping,yes i went by these instructions: but still it seems not to recognize libraries or not compileby kenneth kneebone - Firmware - mainstream and related support
sorry to be a bother, but is this compatible with this wiring set up? or do i have to build sanguino or generation 3? thanksby kenneth kneebone - Firmware - mainstream and related support
Can generation 2 electronics (with this wiring - )be run straight from Replicatorg? do you need the gcode interpreter still , or a generation 2 replicatorg driver, like these? thanksby kenneth kneebone - Firmware - mainstream and related support
ok, thankyou, i know you have to upload and compile first, but was getting so many errors when compiling, does this vary much depending on what versions of firmware you use, and what version of arduino?by kenneth kneebone - Firmware - mainstream and related support
sorry if this is a stupid question, but should the reprap-arduino-firmware folder go anywhere special? i know the library files must be copied, but can you run gcode interpreter straight out of the folder? thanksby kenneth kneebone - Firmware - mainstream and related support
