[QUOTE="charles007, post: 321754, member: 9"] Your pictures are not very clear so I can't give the best advice. Since your new to pressing emax I would switch over to Ivoclars investment and follow all directions to a T. !!!! Haven't pressed in over 5 years but I definitely think your wax looks to thin at the margins. Feather edge margins must be waxed a little thicker, and sprue length and placement are just as critical ! I bought the ep5000 and never once had to repress any emax crowns in 5 years of pressings. My pressing success didn't come from luck, many others on DLN had the same results. Crack detection did go off 5 or so times in 5 years but my crowns were still ok. Great oven ! I sort of think your burnout technique played a part of your crowns, maybe debubblizer, anyway user error on your part. Short margins most likely comes from thin wax. Going to assume your hot ring went straight into your ep3000 without delay. I can't say this strong enough, follow every rule and directions in Ivoclar's emax manual and you will have great success ! fyi. several years later I switched over to Zublers investment, but not because of investment problems. Edit.. important to calibrate your oven ! like some of my friends, I calibrated every 12 months, or more often depending on how much you press.. [/QUOTE]
