That is because u are using the settings for the 1.2 HD version. You need to read more carefully. Every time i post these I try to make sure that the post says "for 50 xy at 31.75 z 1:1 mix on version 1.1" or "30 xy at 30 z 1:1 mix on version 1.2 HD"

Here is what u want to start with and go from there. I have printed using lower setting, but see how your individual machine does. U may be able to lower the T-base and over settings. And maybe the attach layers a little. Start here.

Your print date indicates u are using the original machine (version 1.1) and 50 xy resolution. At least that is what u have chosen in the printer config settings in the "printer manager". If u are using the new 1.2 HD machine u will have to go in and select the correct printer config (v 1.2 at 30 microns). If u are using the original machine (version 1.1) then just make the changes to the settings from the screen capture below.

If u tell me which machine u are using that would help.

Good luck.

Then the settings in your print data won't work, those are for 30 xy and 30 Z on the 1.2 HD machine. The settings i posted just above are for the 1.1 machine and 1:1 mix. Starting pt as I said and tweek based on what u see when u print. Do a test and post pics and I will try to help u. Print something flat (planar) on the back and fairly thin (1.5 to 2.0 mm) so it won't take long to get results. These are service awards but lots of elements to check your printing (Text, small prongs, raised borders, pilot holes for stones, etc.)

When u get prints on the PDMS and not on the build table (and they are cured) then more than likely u need to recalibrate your build table. Did u make sure an "Snap to floor" before saving the layout?

Anytime the first layer sticks to the pdms and not the build table, it's a good sign the initial layer trapped between the build table and the pdms was too thick. This often indicates the table calibration is off. Too high and too thick, too low and when it presses down it causes the table to cock a bit, again creating a too thick layer.

Are u making sure that the build table "floats" with almost no friction when all four of the screws are loose. If u have binding this will make it very difficult to do a proper claibration. Post a picture of your "printer settings" and your "printer management" screens.

Ok i will try. So after i recalibrate it last night i tried another one before i felt and it was sticking to the build table. But now that i checked it its not to the pdms or the table its like a few lawyers feel off the table. If that makes sense. I will post pics if i can get them to upload. That has been my problem my pics wont up load.

If the build "falls off" the table before it's finished then that's an indication that the foundation layer is probably too thick. The foundation layer should be thin, .1 - .5 mm at the most. This this thin layer allows for a bit shrinkage in the resin without popping off the table.

How about a screen capture of your layout and your print screen.
