Rostock 301 1.0.3 Firmware Problem

After upgrading to 1.0.3 my printer does not recognize any negative coordinate values. so now it can only travel in the positive areas away from the origin. When I tried to go back to 1.0.2 it bricked my board and I was only able to use EasyPrint to get it back to 1.0.3 which obviously doesn't work.

Obviously, you need to upload the firmware again.

Same problem here...
The printer, with the latest firmware, cannot move to negative coordinate...
I tried with manual control on software, manualy send a Gcode command and using the LCD movement in the printer!!!
In all case, the head cannot move to negative coordinate!!!

Another BUG....
If i try to move the head (or use the extruder) without Homing, the head crash to the endswitch!!!

I uploaded the 1.0.2 firmware and it failed so I had to reload the 1.0.3 firmware which still has the problem after loading it again.

Using easy print to upgrade to 1.0.3

I tired using the method here on the forums at the end it said FAILED! I can’t remember if there was an error code. I can try to upload 1.0.2 tomorrow to see if there is a specific code.

In the meantime since the 1.0.3 firmware is obviously bad should you maybe pull it?

You should via USB port send G-code G91 to the printer, then send G1 code.
