G-code Error ?

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.

Type of Machine ?
No tool offset that could still be active with a radius/diameter number in it ?

we have a CNC superstar

That smells as the servo following error.
Check your Y axis for binding.

G-code looks normal, I can't see no errors in it.
Cutting in X direction 3 passes, total depth of 13mm.

Thanks for checking that for us ! it seems to be the the y axis is for some reason not working correctly. its reading that it meets its limit but it under the limit by about 12cm. does any one know how we can reset the home and resolve this ?

What controller do you use on your machine?
Settings of the controller?
