My thing I’m printing is 23mm in Z with a 0.2mm layer hight , so that should be 5 layers to the MM , so about 5 * 23 = 115 layers but getting 149 , on global and object all say it’s set to 0.2mm no locks and if I try 0.16mm I get 173 layers .
What am I missing ?
Are you using supports on this part?
yep , but still the maximum hight is still 23mm
it’s a t spaced object 10 + 3 + 10 , the first 10mm supported .
There is a setting where supports can have layer heights separate from the part. That setting can add layers but the overall height remains the same.

You are right it a setting “setting independent support height” which after unchecking says 115 layer , but says it adds 6 minutes to the time.
Your part is printed with 0.2mm layer height either way. But with the independent layer height for your support, that layer height is probably 0.24 or 0.28mm.
Unless you can’t handle a different layer count, I would just keep your original setting and save 6 minutes.
