[QUOTE="AKP, post: 336445, member: 23103"] We had big issues on the beginning with Roland 52 DC. After sending mill back to company and sending it back to us, in the end they told s it was mill issue and they updated it for us to 52DCi which resolved problem. I think that something you should mention. we had technician coming on side and trying to fix it, it was just huge headache with that mill. Toland 52 Dci we haven't experienced issues like that. With that being said, we also had those lines showing in the middle of the crown, and we also had Roland 50 at some point and we had that at both mills. What we did (summarizing whole story): - turned out we were using wrong tools. We decided to go straight to Zahn company and buy from them again as no other tools where ever good -made sure that correct tools where chosen in Millbox when creating case( it does make it a difference you choose Pmma tools to mill zirconia crown - they are not the same) - if you have no issue running calibration (as calibration doesn't stop and doesn't give you errors) then calibration you are running is fine. - if you had sent mill to them and they did calibration on their side, then at this point you need to "believe" them. They can always send someone on site to run calibration as well (they also mill block in wax puck) and you can see if they are actually getting good results - spindle or collet may be an issue. How many hours you have on the spindle, and how does the collet looks like? How long have you been using collet, how does it look like? -x,y,z axsis - we had that issue on Roland 50 where wires were loose. But our Roland 50 was old, and reeeeeeealy overused. You will always have some line on crown, question is how much are you getting? Feel free to message me as I had to figure out everything and it took a while, but I am not having any issues now.
