Thankyou for your reply
Ring test came out very well.
I have run my model again with extra supports using chitu instead of asura and made sure there were supports all around the base and it is better. However the base edges are still wavy.
There is also warping occurring and the print is skewed
A separate print showed skewing but also a layer shift part way through the print
The first print was not round either and I had to print the calibration print to try and cure this issue. the initial measurements did not prove to be the answer and I had to increase the values manually to get a print that was circular.
The prints straight off the machine are very soft almost as if they are not cured fully. I have cured them in a formlabs uv cure oven no heat for 3 hours and they are still soft to the touch.
