[QUOTE="CoolHandLuke, post: 290840, member: 4850"] ok, i'm going to put this out there for everyone to see. you HAVE TO mess with parameters. YOU MUST. I have an imes650, and imes 350. they both run on CAM from the same company. I have done some qualitative testing of identical parts on both machines; just for your information i used material that did not need scan spray, and was a "regular" geometric pattern. on the 650 i saw a consistent 60um overbuild - as though the machine did not cut down to the right size, every time. like the milled piece was 60um bigger in all areas from the design file. this is metrology software you can get for free. on the 350 i saw the same overbuild - but 120 to 200um. yes 200 microns material remaining. we ran the test again, calibrated, ran the test, calibrated, a process of 7 times. there was NO improvement. NONE the problem is the CAM. the CAM was ordering the machines to leave this much material behind. when i peeked behind the curtain i was able to ascertain why the machine left material behind - and by process of opening these menus was able to reduce my problem to one i know how to solve. my machines are now consistently outputting less than 40um in accuracy. i'll shore us up when we start doing implants but for now theres nothing wrong everything fits well. so there is no question to me anymore; NEVER leave defaults as they are, they are wrong. they are bad for you, you must absolutely change them - in my case it was for accuracy sake. in your case i think a change in spindle speed would have been a propos. you broke two spindles. thats the sign they arent running right. if you don't know how or arent sure what needs changing, do not be afraid to call your CAM provider for solutions. CAM drives your digital production so if they can't get it right call someone who can. now, as i know you have an imes i can recommend you to call Articon in California and have them take you on as a customer - they will want you to purchase their CAM software, and I can vouch that they know what they are doing and are more than capable of keeping an imes machine running like a clock. if you are interested in having your imes work right its probably one of the two places in the usa that can help you out.
