Would some one be able to inform me if there is an issue with this g code ? I am simply trying to cut a board a metre up and it is cutting at 80/90cm . When looking at the drivers they read ER 020. Looking online this seems to be an error in the G code. Once the Y axis drivers show this error code the Y axis does then not move.
