Rings coming out Oval

[sabushka]

Hi
Can anyone help. All my rings seem to be printing slightly oval in the Z. With or without supports. What am I doing wrong.
Thanks

Please check the measurements in X and Y and compare them to the STL file. If you find either X or Y is out, you can try adjusting via the "zoom" on the projector (don't forget to re-focus), but you may get a better result using the controls in Solus Contour File --> Setup --> [Project Grid]

I had this problem. You just need to work out what percentage taller the Z height is, then compensate for that with the scaling tool in Contour.

So, for example, my Z height was 2% taller, so I scaled the models in Z to 98%.

I am running my first sets of prints. I am having a similar issue, my rings are oval instead of round. Is this the best answer to scale in the Z or is there a more permanent fix?

If you change the Z in the Contour software will it remember it or do you have to remember to set it every time?

Sorry I'm a nubie at this printer

Thanks

Please make sure your grid size and ratio are correct. There is no reason to get oval rings unless your xy dimensions are off.

Thanks I will have to double check those measurments

I had the same problem. It took forever to find this fix.

Will this calibration also effect the overall size of the models as well? I noticed my models are a bit smaller than they are supposed to be as well. To be fair I am measuring the ones tht are a bit oval.

When you have the grid calibrated correctly, the prints should be the right size, not counting shrinkage from the resin.
