Sorry for the late answer! I have attached the cam files!
So I read what you wrote Cadfan and what should i have to do?
Diamond coated ?? you have a 0.8 burr ??
i have got 3 milling bur,2 mm, 1 mm and 0.6 mm and this is the order as well! and no not coated diamond.
Ok non coated burs if you run them more than 10 hours they are dead you 20 ??? in your cam is a 0.8 burr included a mistake ?? chipping starts on non diamond burs at around 6 hours.
2 mm burr is quite fast for non coated 1800 mm xy and 1200 in z 1000 full cut and 0,8 delivery
But this problem isn't occur with PMMA.
WHICH PROBLEM PMMA IS A TOTALLY DIFFERENT MATERIAL ??!! wrong burr , chipping ,high speed ........................................
your cam file your burr ?? 0.8 ?? 2 mm goes down to .1 offset with that speed old burr ???
Ok so you think this is the problem what causes the chipping? What do i have to do? What do i have to change and where?
Change tool to 0.6 look if the rest ( shaft) is ok ( or ask reseller) change your tools sooner ( 10 hours) versus have a look at small chips some stl s and zircons are harder to mill
in general ht s tend more to chip small crowns with ups and downs and big undercuts need slower strats ( ask reseller for a slower strat too )
? is it the wright tool versus syntax for the tool 0.6 every tool has a syntax for ex D0xB- for a 0.6 tool zirkon and position in the toolchanger here P 3
fyi, found some inexpensive Roland diamond tools from TD Dental Supply....got nearly 100 hours on a bur and i switched it out just in case. far better than the $160-$200 tools ive tried from a handful other suppliers.
might be worthwhile snagging some for yourself.
