Hello

[Met63]

Hi I am new to cnc and have just built my first machine, it is 3m x 1.6m, I have it up and running and have all the motors tuned but I am having some problems when cutting circles and squares and 45 degree diagonal lines are coming out with an arc and not straight, don't know where to start to sort the problems I am having, any ideas of what order I should start the process would be very helpful. I have attached some pictures below, the problem with the circles if I move the start/finish point from 3 o'clock to 9 o'clock the problem moves orientation too ???? ( see circle photos below)
