As I understood (correctly?) from this thread: Z-Compression Correction question
There are several factors influencing how much the Z-Compression Correction needs to be:
- Type of printer (I guess values are different for Form 2, 3, 3L…)
- The tolerance on the hardware parts and assembly of the printer / vat
- The composition of the resin: (I guess some are more compressible than others)
- The total surface area of the first layers: (The bigger the area, the less compression can happen given the same spring force)
- Layer height: (may be curing parameters alter the amount of compression of the resin)
- (what else?)
hat else?)
Except for 2, I guess this value could be calculated by Preform at some extent.
Now it just a field left for the user, but the amount of experimentation needed is not only a lot and expensive, but also needlessly duplicated by every user.
