leveling does not go to all four corners, stops in about 4" square, is it LCD program?

I have recently had a lot of trouble getting the new main board and LCD to flash right. I finally got the motors working correctly but now the leveling does not got to the far corners but makes about a 4" inch square apart on the left side of the hot bed. How is this adjiusted or is it not the right flash for the LCD?

HI Gary, it could be either firmware is wrong. More likely that the main motherboard firmware is wrong. Which printer do you have, and which firmware link are you using for main and LCD firmwares? Cheers, Sam

The way to find out would be to use a PC program (pronterface) to control the printer, and see if the limits are being enforced by the main motherboard, or, if the LCD is sending the wrong coordinates. When using the 5 point levelling feature on the LCD, the movement coordinates are set in the mks_config.txt file in the LCD firmware.
