I will add that avrdudess was a huge help, the link is also above.by AriesPrinters - Next Wave Electronics Working Group
Treading through my notes and based on My posts and what I remember, it was a while back, the thing that finally got it going was writing the fuses. However you are having connection issues. Wiki is your best friend, approach it with a clear head, the answer is there. Above are important points I had missed or didn't fully understand. I would advise simply checking everything step by step and excby AriesPrinters - Next Wave Electronics Working Group
Yeah, I looked further into it. Moving it into a different location and shielding it from any drafts is a lot more practical.by AriesPrinters - Reprappers
I was wondering if is it worth it putting a printer into a vacuum. As there will be very little oxygen there is next to no chance of a fire and the heat will have a harder time escaping from the heatbed and end. Just a thought. I would like to have prints that go over night on my Prusa i2, but I don't yet trust the open style printer with a home sodered gen 7 board.by AriesPrinters - Reprappers
I've been playing with my I2 for quite some time now and it's time for an upgrade, I am designing my own and these are the current two projects on mind. Bed Z, Hotend X,Y Advantages: -Allows for faster prints -The object is less likely to dislodge compared to a Bed X,Y (explained later) Disadvantages: -The correllation of the gantries speed to weight is directly inversely proportional (more orby AriesPrinters - General
Answer to my own question here It all comes down to if you are using lead screws or threaded rods, with threaded rods it proves to be an advantage. All explained in the article above for those curiousby AriesPrinters - Reprappers
I got around finishing my first low budget printer a couple of month ago, the Prusa i2 , and I was just wondering why aren't the z axis motors on the bottom instead of the top? Occasionally this gets pulled out and falls and it seems that it can completely be avoided by placing the motors on the bottom. This would also lower its weight from the top to the bottom and possibly make it more stable.by AriesPrinters - Reprappers
Quick edit: I got impatient, took to my gut and did it... It worked. And that people is how you program an Atmega1284 in 3 weeks... wish you all the best of luck feel free to comment if any questions arrive, I'll be more than happy to help outby AriesPrinters - Next Wave Electronics Working Group
FIX for the boot loader: I ended up connecting my atmegas (I now have both, P and non P) to a bread board and connected 9 of the pins like wise: USBASP ATMEGA1284/ATMEGA1284P GND---------------------PIN 31 (gnd) GND---------------------PIN 11 (gnd) RXD---------------------PIN 14 TXD---------------------PIN 15 VCC--------------------PIN 10 MISO-------------------PIN 7 SCK-------------by AriesPrinters - Next Wave Electronics Working Group
Embarrassing update: I had the self prog pin in place after miss reading some certain information, didn't take another hard look at the programmer until today. That bit is pulled out and now the dreaded usb not found message has disappeared However at a cost of something much worse... I fear I may have fried the chip. With and without the chip I get: avrdude.exe: set SCK frequency to 93750 Hzby AriesPrinters - Next Wave Electronics Working Group
Didn't have much time, and I still don't untill the week is over so I haven't recompiled the bootloaders yet... I tried to load directly from the usbasp without the bootloader for a quick fix. It said Com port not found and such, I checked and the programmer has no com port. I would think it wouldn't need one. Before I get at it again tommorrow and download a com port emulator, does anyone know iby AriesPrinters - Next Wave Electronics Working Group
I'm going to try to troubleshoot on Windows instead, I have more experience with it. I spent some time reading the other threads and as it turns out wierdly enough there is a difference between the atmega1284 and atmega1284p besides the picopower feature... I have the NON p. I changed the signature in avrdude.conf file to 0x1e 0x97 0x06 , but the same message persists... are there other factors tby AriesPrinters - Next Wave Electronics Working Group
I can't get my head around the permissions on linux. I followed the instructions on ArduinoPlayground and attempted the ArchWiki link, but to no avail. Couple of points: 1) In ArduinoIDE the serial ports are greyed out, can't even select one (where as in windows I can select a com) 2) When typing in: gpasswd -a $user lock , it says: gpasswd: group 'lock' does not exist in /etc/group Whenby AriesPrinters - Next Wave Electronics Working Group
Spending 7 hours unsuccsefully trying to load a bootloader is something nobody should go through... alas, I have. I'm just praying someone is able to find my mistake. I tried these steps on an Inspiron M501R(duel boot both linux mint 17 and Windows 7) and an older Inspiron with Windows 7. Here is what I did (among maaaany other things): 1)Ordered a usbasp 2)Made a custom cable, 10 pin to 6 pin 3)by AriesPrinters - Next Wave Electronics Working Group
I recently completed the gen 7 1.5 board for my printer and I'm having trouble uploading the firmware to the Atmega1284-pu. I followed these instructions... all well except the zip download doesn't work and I don't have a programmer. I did all I can by improvisation and other sites and ignored the bootloader process(I'm not sure if mine has one or not) and uploaded to the microcontroller from ardby AriesPrinters - Next Wave Electronics Working Group

I was supposed to print for the first time this week, but after some final tweaks the ramps board and Mega 2560(not Arduino original) burned out. The power is getting through the 5A fuse(the one near the two fuses) but not through diode d1 which shows 0V. The Mega 2560 won't connect to my computer, it was found as an unkown device both on Linux and Windows. Also the leds shine brighter with the mby AriesPrinters - Reprappers
