I am having the same problems with my MCX5. It is not a TRUE 5 axis and is requiring a lot of time to finish the restoration by hand. Embrasures, not milled arias bellow or above the sprues on frameworks and so on.
They say that the new software that comes out in September will take care of most of the problems. I will bereave it when it happens.
The mill is very accurate when I mill zirconia cases only. I have not been able to get accurate results in wax. I am talking about the fit. I tried to play with setting but I just cant get it right. I was told that the smallest bur it uses on the inside of the crown is 1mm. We also have 0.5mm but only for outside. I am thinking that this can be the reason for my poor fits in wax.
What do you think?
Well when we first got the machine they said that the new software was coming out in August...it is almost September now. I won't believe what they say until it actually comes out.
Also, we did a test run on a emax block. The results were horrible. They want you to use the grinding method to make an emax restoration, but the smallest burr they have for grinding is a 1.2mm diamond burr. Needless to say, the anatomy didn't come out at all. As for the wax we havent even tried it since the emax test went so bad, my manager doesnt even want to waste the material on testing it out, but it would make sense that the fit would be bad when they use a 1mm burr for the inside. It's very obvious Sirona didn't really think things through with the MCX5 before they made the sale public and part of that I blame on the Beta testers. All of them are in the pockets of Sirona so I have a feeling they didn't really do their testing well, otherwise Sirona might have waited another year or 2 before going public with it. And I keep on hearing from Patterson that Sirona kinda threw the software together from parts of the inLab software. I'm really beginning think the MCX5 is just a huge money grabber for them.
So it sounds like there will be a lot of wasted material? From my three years with sirona mcxl, it was miserable. I'm sure things are better now but I keep seeing the same type of crap happening on the Facebook inlab study group. Sad thing is I've actually started to consider getting back into sirona. (Shame)
Well, I did have to waste a nice chunk of a disc, but know I know what the issues are I've been particularly careful on dealing with the software.
ALSO GUESS WHAT! Something went wrong with the MXC5 AGAIN!
This time around it has to do with..wait for drumroll....AIR PRESSURE!!
So I was in the middle of a mill project when an error message showed up saying the the mill was "timed out, please select continue to restart the mill"...there was no "continue" option, just "Stop". So when I hit stop then next option did show continue but as soon as I pressed it, the screen for the tool changer showed up saying that there was no burr in the spindle. I went to check the mill and there was no burr in the spindle, it had dropped it. This was so frustrating. I had done everything Sirona asked me to do to keep the machine at optimum performance and I keep on getting my butt kicked by this darn mill...now I have to wait until Tuesday for them to come and replace a part for the air pressure....seriously....someone please come to my lab and steal this mill so we can claim insurance or something...
