Can't upload the Firmware when MAX_HARDWARE_ENDSTOP_Z is changed to true

Hello,

I am trying to upload the repetier-host firmware on ATMega2560 + Ramps 1.4 for my Delta Printer
But it wont. It will always stop uploading at 39% with Arduino IDE 1.5.2
Arduino IDE 1.0.6 results the same problem.

This happens when I change

Quote
configuration.h - 0.91 Rev 8
#define MAX_HARDWARE_ENDSTOP_Z false

to true

See here at the last line:

Quote
configuration.h - 0.91 Rev 8
#define ENDSTOP_PULLUP_X_MIN true
#define ENDSTOP_PULLUP_Y_MIN true
#define ENDSTOP_PULLUP_Z_MIN true

#define ENDSTOP_PULLUP_X_MAX true
#define ENDSTOP_PULLUP_Y_MAX true
#define ENDSTOP_PULLUP_Z_MAX true

#define ENDSTOP_X_MIN_INVERTING false
#define ENDSTOP_Y_MIN_INVERTING false
#define ENDSTOP_Z_MIN_INVERTING false

#define MIN_HARDWARE_ENDSTOP_X false
#define MIN_HARDWARE_ENDSTOP_Y false
#define MIN_HARDWARE_ENDSTOP_Z false

#define ENDSTOP_X_MAX_INVERTING false
#define ENDSTOP_Y_MAX_INVERTING false
#define ENDSTOP_Z_MAX_INVERTING false

#define MAX_HARDWARE_ENDSTOP_X true
#define MAX_HARDWARE_ENDSTOP_Y true
#define MAX_HARDWARE_ENDSTOP_Z true // <-- problem!!

You should remove the comment if you want that enabled if I am not mistaken.

So the code would look like
define MAX_HARDWARE_ENDSTOP_Z true (NO # sign in front of it)

it still doesnt work, this wouldnt recognize as c++ syntax??

That is a strange problem...

If I understand correct, you can compile the firmware without errors with both true and false,
but when you try to upload the binary it always fails with true and always succeeds with false?!

As far as I know, there is no connection between that setting and the upload mechanism...
The upload process is not interested in the meaning of the file, it only transfers 1's and 0's.

I *think* that you can even upload a binary that only contains zeroes, without errors.
But I have been wrong lots of times before, I would love to be corrected on this problem

Do you have a second USB cable that you can try?
Do you have a second PC / laptop that you can try it on?

Thank you for reply. Yes, you understood correctly. Its very strange for me too. There is no compiler errors. When I upload with the "false", the led on Arduino Mega Board is blinking fast for long time (around 20 seconds) and it succeeds . When I change the MAX_HARDWARE_ENDSTOP_Z to "true", then its blinking fast about 2 seconds and then it stops. When I restart arduino, the display shows nothing.
I've testet it on other Arduino Mega 2560 (and also without ramps 1.4)-> same problem

Okay, your idea is good. I'll try on other computers and other arduino mega 2560 boards and inform here.

On Notebook there were same problem.

But I've changed the Z_HOME_DIR 1 to -1 and now it works!
I don't know why it was 1, it was generated by firmware configuration tool. The Printer Type was always selected to Delta Printer
