Cannot upload grbl to card.

[lowplainstu]

Hi
Everything was working fine but I started having issues homing my CNC and running the spindle.
I've rewired everything to ensure all is OK.
Tried all sorts.

However, I can't now load grbl to the Arduino Uno. Keep getting error messages. Any help would be appreciated.

Attached image shows screen shot of Arduino errors.

Thanks in advance
