cutting not equal

[paddy ireland]

Hi i would appreciate any light you could shed on my problem <i built my own plasma cutting table which works very well,however when i do a drawing of a rectangle say 300x200 and put a 20 mm hole in the centre and cut on the plasma table the hole is off centre on the x axis by 5mm ok on the y axis so all feed back appreciated. Tnx in advance
