please see the attachment.

Modifying the firmware solved the reversed motor.

Using Repetier now, I can make all carriages go up using +z.

There is still a problem. In manual control once the carriages are up, I can't get the -z to work.

Also, pressing the x and y buttons only seem to make the carriages go up. I don't have the spider connected because it already broke one of the carriages, and I can't print a part until I can get this printer to work.
Did I miss something, is there a custom setup for Repetier to use with this printer?

Many thanks!

hi, the following link is a setup for Repetier to use with rostock mini.you can have a try.

ragarding to the broken carriage,you could buy a new carraige since the broken one may interfer with the printing quality.

I bought the G2S for more than a month and it is still not working. The GT2560 is giving command waiting error in Repetier and the LCD is showing only blocks. I am trying to reburn the firmware to the GT2560. The firmware I downloaded from this forum was verified/checked successfully but when I upload, it gave timeout communicating with programmer error as below. I am using Arduino IDE 1.0.5. It can detect the GT2560 because it was picked up as COM3 when I checked under tools. Is this something to do with missing bootloader or the board is bad?

hi,the board is ok as it could be detected by pc.regarding to comand waiting error,maybe some wires connected to mainboard are loose,please turn off printer and repluged the wire.then restart the printer.
regarding to the block on LCD,please screw the screw at the back of LCD,it was used to adjust contrast ratio.
the latest firmware for g2s has been sent to your mailbox.

Thanks. I will test it again tonight. Question.Can I remove the GT2560 board from the printer to perform the firmware uploading only using the USB cable you have provided?

For those having trouble with the auto leveling probe dancing around and moving up, check that your z_min is open when the probe is down (look at the output after probe is down and send M119 command). If the z_min is Triggered, then the probing sequence is always going to think it's hitting the bed and will keep running up until it crashes at the top.

If your z_min is triggered, you need to get the firmware posted above: http://www.geeetech.com/forum/download/file.php?id=1146 and modify Configuration.h

const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.

to

const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.

Also, if you find that your homing speeds are crazy fast and you're afraid you'll break the endstops at the top, lower the homing speed to an acceptable value. Min is:

// delta homing speeds must be the same on xyz
#define HOMING_FEEDRATE {35*60, 35*60, 35*60, 0} // set the homing speeds (mm/min)

yeah,please turn off the power supply when burning firmware.

Hi, I just managed to find time to re-burn the firmware. Now I get a loud beep from the LCD controller plus Repetier is showing maxtemp error on heated bed. I can also see that the temp is around 200C on both the hotbed and extruder. This is immaterial whether I connect the 2 heat sensors or not. Both thermistor resistance is around 75K is fine. I check the configuration .h that the sensors are set as 1 for 100K which is correct. What seems to be the problem?

I'm getting odd issues when connecting the printer to repeater software and home only seems to move one axis to the stop then grinds as it tries to go down even with no binding. Moving the axis with the LCD works on all areas but home still does not work. The endstops work correctly I have verified with M119 and manually triggering them and moving them one axis at a time with the LCD works but Home still has the issue going down.
