Hey guys,
I would also love cooling for perimeters, because with some parts where there is some bridging it doesn't automatically turn the fan on for the perimeters (that are actually bridges) and the whole thing ends up pretty messy.

Hey,
got it working with Marlin firmware. Will try to get it running with repetier, because I like it better but for now I'll have to use Marlin.
Any help would still be appreciated.
Thanks,

Firmware - mainstream and related support
Hi everyone,
i had a LCD with a rotary encoder hooked up to my Sanguinololu running Repetier Firmware. Now I need a fan for cooling and try to get my Control Panel connected via I2C.
It seems that Repetier supports this but, I don't have any knowledge about how addressing etc. works.
I attached the schematic of the circuit I use.
Could you please help me with the configuration in the firmware?

Firmware - mainstream and related support
HI everyone,
i was fiddling around with my Sanguinololu board today and shortly after I powered it on the screen of my lcd went black. Thats when I noticed that one of my bullfrog clamps was lying under it and must have caused a short and the 5V regulator overheated.
Now I can't upload firmware succesfully to the board, I always get this Error:

Firmware - mainstream and related support
Hello again,
i got an Atmega1284p so that i can print from SD card now and the problem with the slow motors was really a firmware setting!
Got it all working again, just need a new Pololu and then i can finally print again
Thank you for your support!

Slow as 12.5% maybe. But now i seem to have bricked my ATMEGA, i get "initialization failed" and have tried some solutions i found around the ineternet but none worked so far.
And I am wondering why i was not able to upload the firmware through usb anymore.
When i get to some state where i can upload firmware again I'll post here again.

Hi,
thank you for your reply. The fuses don't seem to be the problem, I have checked them again and again now and still the same. I tried the fuses which are in the boards.txt from the Gen7 support package - they are the same for atmega644 and atmega644P - i have a atmega 644A so they should also work. According to the datasheet they all share the same fuse settings.
Is it possible that i need a

Hi again,
i got a avr programmer and flashed the gen7 bootloader onto my atmega and switched the resonator with a crystal and 2 capacitors. I am only able to upload firmware to the atmega using the programmer so far, but i am able to connect to that firmware with NO communication errors.
But: the steppers are moving very slowly - is it possible that this happens because of one stepper driver mis

Now i soldered cables between the rx/tx pins and the atmega, still no success.
Seems like this board is not going to work
Is it possible that only the serial part of the FTDI is broken?

If i try to upload a firmware via arduino, after a few seconds it stops with the following errors:

Hi repetier,
I have two sanguinololu boards, and one is working flawlessly - but i can't connect to the other one. I have detached everything including the stepper drivers and power the board only through usb.
Most of the time the commands are just qeued up (the initial ones), sometimes it connects but immediately disconnects after a few seconds due to too many errors. I have interchanged the AT

Hi again,
i just can't figure out what the problem with the electronics is, is it possible that i damaged the ftdi while soldering it to the board?
Windows does recognize it without problems though.
Any suggestions on what i could check?
Thank you very much

Hi!
i have the same problem with layers not sticking together. I use ABS and extrude at 230°C.
Some help would really be awesome

Hi again,
would it be possible to power on an atx-supply with one of the pins of the IO-Header if i set it in the pins.h?

Okay, maybe I'll switch the two cables with a coaxial one, then i should have no problems with this.
Thank you very much for your help and also for your Firmware and Hostsoftware!
I'll report back here when i get the other board running.

Ah working! Thanks again
I have only one problem left, and its probably also related to this crosstalk: My x-Achsis does not always move to the endstop when homing - probably because my cable is too close to the motor wires or?

Printing works relatively good, except that during printing a shift in the x-coordinates occurs.
What can be the reasons for this behavior?
I already tried reducing the feedrates and accelerations but with no success.

Okay i will contact my supplier!
Now i have another problem: the x-axis won't home. When i click home, the axis stays where it is and the x-coordinate in the host shows xmax (200) as current coordinate.
I tried various inverting of endstops settings and inverting the x-achsis homing direction in the FW but they did not help. My x-endstop is at x-max
What should i do ?

Hi again,
yes the board works! But only after i cleaned it, too. But there are no errors and i did not change anything in the firmware configuration!
Now i just have to find the problem on the other board.
But one of the Polulus on his board is not working, its overheating the 5V Regulator. Is that possible to fix?

Okay i'm pretty sure that would be a problem. I bought a kit from xyzprinters.com i hope that all parts are the right ones. But it does not seem like sanguinololu has any coils (RepRap.org assemby instructions). I just cleaned the PCB from the remaining flux but this also did not help.
Now i am again not able to connect to the board - very strange.
I also speak german (and write) if you prefer i

Hi!
I meant to compile it without SD support, thought that this was necessary to achieve this:
*/
#define EEPROM_MODE 0
/** Comment out (using // at the start of the line) to disable SD support: */
#define SDSUPPORT 0
I did not mean to ignore your suggestions! Just thought that the above statements disabled EEPROM and SD support
I found that the source and drain of the hotend mosfet where sh

Hi repetier,
i have selected 250000 baud in the firmware and in the host. I used the "Gen7 Arduino IDE Support 2.0" because i read that they were more up to date and selected a "Gen7 with ATMEGA 644P and 16Mhz".
Is this the problem perhaps? I will try the ones from www.sanguino.cc and report back.
Thank you very very much!

Hmm, yes it shows up and does not give any errors. It's always on COM3 no matter where i attach it to, so this is not the problem either. Most of the time the commands are just waiting, even those which are sent when clicking connect.
I just managed to get it to do just something but nothing good. Here's my complete log from the Workdirectory:

Okay i restarted windows, still the same. Then i plugged it into another usb port on another controller and still the same. I will try to get a shorter usb-cable and try it again when i get one. I am using a 3m cable i got with my electronics kit, maybe this is the problem. The cable works fine with my normal printer though.

Sorry for not giving you enough information
The errors in my last post show up after clicking "connect" in the host interface. Nothing else was clicked. I have disconnected everything except the usb cable and removed the pololus.
I could connect the printer to a LiPo battery, that would be the most stable power source i can imagine. The PSU is quite stable when i charge my LiPo batterys with i
