SOLVED: Just wanted to let anyone interested know that I solved it. The programmer must be set to "arduino" and not "stk500".

Thank you very much.
It has definitely changed something.
But then I receive a very unspecific error message:
"An error occurred while uploading the sketch"
I get a more detailed error message when activating "Show verbose output during upload":
Using Port : COM10
Using Programmer : stk500
Overriding Baud Rate : 38400

Hi,
I am trying to upload Marlin 1.1.9. onto my almost 8 years old Sanguinololu 1.3a, which features the atmega644P (I guess at 16 MHz?)
Compiling of Marlin under Arduino 1.8.12 works fine, but when trying to upload I get the following report:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x6f
I've followed now all the advices I could find on the web, including the one of Jua

Just an update for those who are interested:
I've made some progress in the meanwhile, partly by printing much hotter (up to 210°C).
Another improvement was the new plastic I'm using now: the white PLA seems to be a bit softer than the uncoloured one and breaks less often.
I have the feeling that the parts I'm making are quite strong in the meanwhile. Nontheless, I've so far always failed to cl

Hi,
there is something that I don't quite understand. I would be grateful for some helpful comments:
(I'm printing PLA using Slic3r with a 0.5mm nozzle)
-) I've calibrated E-steps, and in general, the filling of objects seems to be quite right, apart from the fact that holes (also rectangular ones) are always a bit too small by about 0.5 mm or so.
-) So I printed the "thin wall object", which

Hi, I am having problems with my parts being very brittle. Especially bar clamps break very easily.
I am printing PLA at 185°C, nozzle dia. 0.5mm, layer height 0.3mm
Obviously, the layers don't bond very well.
From what I learned so far there are three main reasons for this:
A) too low temp. --> I already imcreased the temp from 175 to 185, with no improvement.
too little material used? T

Think I solved the problem (at least for most situations):
I have a second fan installed, but the biggest improvement was made by the newest version of Slic3r, which seems to be more clever than the old version I used before. It seems to drive more slowly when needed.

For those who are facing similar problems, here is finally my solution: I used Marlin instead of Sprinter. This worked without problems.

Hi,
I am quite new in the printing business and about to calibrate my Mendel Prusa.
I use a Wades Extruder 0.5mm nozzle with 3mm PLA filament, Slic3r for generating G-code.
So far I printed with layer heights of 0.4mm or 0.3mm.
I tried to follow the calibrations steps on:
but have troubles getting the things nicely printed.
The filled box became resonably nice, but the problems started wit

I followed the "Complete beginners guide" at:
According to this guide, one is supposed to first execute "make" (outside Arduino IDE it seems, which is why I installed Cygwin) and subsequently to compile another time using the Arduino software.
Please let me know if you think this is not the right way of doing it.
My system runs on Windows XP by the way.

Many thanks.
I am just struggling to update the firmware. I am trying for days now to compile Sprinter under Windows using Cygwin.
Executing "make" however doesn't work flawlessly. :-(

Hi,
tried the whole afternoon to compile the Sprinter software. (under windows)
I always get the following error when pressing the "Verify" button under Arduino v0022:
In file included from arc_func.cpp:26:
/Sprinter.h:8:26: error: WProgram.h: No such file or directory
In file included from arc_func.cpp:26:

Hi,
Yesterday I was powering the motors of my Mendel Prusa for the first time, with the following result:
All axes are moving back and forth (by half a centimetre or so) in an uncontrollable way.
This happens also when the Sanguinololu 1.3a is not connected to the PC. The motion rests for a while when I press the "reset" button on the board but then starts again.
When I try to connect to the
