[QUOTE="ps2thtec, post: 350405, member: 3335"] Let me add more confusion. When I first started pressing emax years ago with a non-ivo oven I had to try and try, and settled on these parameters. (See pic). Compare to ivo. [ATTACH alt="6129123C-59A7-4931-870C-F9C9A4D19F38.jpeg"]40882[/ATTACH] Your burnout seems high. I use 1565F, one hour soak. What size ring. That changes things also. small ring….4bar large ring …4.5 bar my ivo ep3000 Presses a ring in about 1:15. When setting my old oven I had to set a press time that took 4 minutes or more. That will increase the reaction layer. Sprue placement could maybe cause more issues.
