Arduino Mega 2560 / Ramps 1.4 with Repetier host

Remko

Hey everybody,

First of all I want to say I've got little to no experience in computer programming or 3D printing, just wanted to follow this project as a hobby for fun: http://www.instructables.com/id/Arduino-Controlled-CNC-3D-Printer/step17/Configuring-Repetier-Firmware-for-Arduino-Mega-256/ So far everything went smooth up to the point of succesfully uploading all the firmware to the arduino with the CNC configuration settings. However when I try to connect the repetier host software with the arduino / ramps board I think something goes wrong.

I think the connection is failing, but I'm not sure about this. All I know is that I get the following error:
11:15:52.762 : OpenGL version:1.1.0
11:15:52.762 : OpenGL extensions:GL_WIN_swap_hint GL_EXT_bgra GL_EXT_paletted_texture
11:15:52.762 : OpenGL renderer:GDI Generic
11:15:52.762 : Fast VBOs for rendering not supported. Using slower default method.
11:16:36.754 : Printer reset detected - initalizing

11:16:36.785 : Free RAM:5438
11:16:43.743 : Warning: Seems like we missed a ok, got a wait - continue sending.

And if I go into manual mode and try to adjust the position, the stepper motors dont do anything. So anybody has any clue what I'm missing (And please remind Im a total beginner in this 3D printing software)

Hi Remko

i am busy with the same project, i am a little further than you once you have uploaded the firm ware to the arduino board, open
the repetier software then set you printer settings to the correct coms port. and board rate then click connect icon.

I had to turn off all my hard ware end stops in the config h. before i got any movement

@Remko you are using the wrong baudrate or wrong port (if you have multiple ports). For that reason no communication occurs and nothing happens.

A independent provlem is

11:15:52.762 : OpenGL version:1.1.0 11:15:52.762 : OpenGL extensions:GL_WIN_swap_hint GL_EXT_bgra GL_EXT_paletted_texture 11:15:52.762 : OpenGL renderer:GDI Generic

meaning our OpenGL library did not find the opengl driver from your computer and used a generic slow/expired version. So you have not installed it, the bit depth is not 24/32 pixel or it has a problem with your driver version. Especially intel driver seem to cause this problem - some work others not especially when combined with dual grahic drivers. Some users have reported that you need to set in power saving the graphic card to full power.

Solved this issue :D Thanks guys
