Firmware reset problem

[gleb]

Hi, I've download Repetier-091-ROSTOCKMAX and used this video instruction [youtube]http://www.youtube.com/watch?v=A4yMV18oMbw[/youtube] to set configuration options. After compilation and uploading to board printer moves extruder down until it bed and keep doing it. If I move it to top position and touch stopends motors moves reverse direction. Probably I made mistake in inverse direction somewhere.
I've tryed to press reset button in RAMBo - printer stop moving until I release the button.

How I can load new program or reset to default settings?

Should be around lines 190 in the configuration file that you need to make the change for your machine.

//Set direction to 1 to invert
#define INVERT_X_DIR 1
#define INVERT_Y_DIR 1
#define INVERT_Z_DIR 1


^This is the code for my particular machine. If your # after "_X_DIR" is set to 0, change it to 1 and vice versa.

Thank you for hint, but how I can upload modified code? When I turn on the printer it moves down and doesn't stop when touch platform. I have no time for sending code to the controller board.

Ah, gotcha. You must have home on powerup enabled. Welp, there are a couple of "solutions" One would be to temporarily switch the jumper on the Rambo to the USB power rather than the CPU power. That would allow you to power only the board from the USB (turn the CPU off) and resend the modified code. The other way you could do this would be to disconnect the stepper connections from the board. The board will be trying to send the carriages down but they won't receive any actual power then. The minute the board begins getting new code it stops whatever else is going on, so the power output won't be for long and you can then plug the connections back in. I would be sure to disconnect power before moving the jumper or unplugging/replugging the connections to avoid any fried components.
