Ok I did some changes (like inverting some directions…) and I just can’t get it to work. Here is what happens :
When I connect the reprap, I can read the temperature, I can send M119 to see if the endstops are triggered. Then when I press homing, the reprap starts homing, but when then it passes the endstops without stopping, and keeps going till it cannot anymore, because the belt is preventing it. Just like it doesn’t see the endstop, or even if it does see it, keep on going anyway. That is why I then tried to disable the pull-up resistors, but nothing changed.
Also, when homing, I can’t anymore require information on temperature or whatever. If, when homing, I send M 119 or I request the temperature via the button in pronterface, I don’t receive anything.
I’ll try some other tests, but if anybody had an idea, I’m open to suggestions…Do you ever sleep ? o_O

// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR 1
#define Y_HOME_DIR 1

#define Z_HOME_DIR 0 // Bed home to top (0)That doesn’t solve the problem…
Thanks for the help Quentin ! But maybe I should’nt ask for it at night, you should have the right to rest sometimes…Ok here’s what I get when I connect the printer to pronterface. I post it so that you who knows what happens usually can maybe detect something weird happening.

ok T:20.6 /0.0 B:0.0 /0.0 @:0 B@:0OKay first I’m stupid. The z endstops was in the place of the X or Y. I put the Zendstops in the right place, but which arm is the x and which is the Y ? So that I can put the endstop in the right place ?
Then, with M119, it tells me that the endstops are triggered when the flag is not on it. Shouldn’t it be the opposite ?
That is, the flag should trigger the endstops when the homing position is reached. Right ?OK thanks Quentin, I’ll try that. But I don’t have any hall-effect sensor, I opted for opto ones. (uhuh) They give a 5v on the signal wire when you pass the flag between the 2 captors.
It looks like I have a homing problem. I tried several things this afternoon looking at this wabpage :
http://forums.reprap.org/read.php?146,125056,137250Still I couldn’t manage to have the homing done properly, that is, the arms won’t move to the position where the endstops are activated when I home the reprap. I will try again tomorrow.
Ok now the homing seemed done, even if only one of the endstops was activated. Then I could move the arms (gently) but as soon as I pressed the home button again, the arms abruptly changed positions, really fast, and then stopped.
After doing it again I think I can’t move , it just does it by itself. If I look to the connection on my motors they are not in the same sens, I’ll change that. Which makes me think it is actually doing the homing movement. Still when it passes the opto endstops it’s not stopping. OK I try again.
Hello !
The problem is that I don’t know where to mesure the tension on the potentiometer. It’s so tiny :s
Anyway I installed the 2 endstops for X/Y now, but when I press homing, the arms just move abruptly, then stop abruptly, then start to whistle and do not move till the endstops. At that moment I think that the reprap is not responding anymore, because when I send commands like “read the temperature”, I just get no response. After a certain time though, I think the homing is done, because I can move on X, but then it just goes all the way till it blocks itself because the angle between the two arms is too big.
Hello ! Thanks for the help ! As I had a small piece of ptfetube, I put It in series with my lrss-heat-resistant tube. Seems to work when I turn the wheel of the extruder by hand. But then I got to check my motor, because it’sonly whistling when I try to extrude filament, and the filament doesn’t move. Maybe the current Is Not sufficient ? What do You think ?
The kitchen foil seems to be ok, I mounted and tested the j-head and pronterface seems to read temperature well.
My next question regards the Martin software. Is the conversion of the coordinates done in the arduino ? I think it is, but when I move one one axis (x or y), I have only one motor turning, though they should be both in action to trace a straight line. Is There something in the arduino code to comment/uncomment that I may have missed, needed for the morgan only ? well.
