5 axis nothing else a simple single unit can bring a four ax out of range especially if you mill on 1 to 1 ratio like pmma , wax, or hard stuff
your mill is your cheapest employ 350 with loader 1.4 buck per month .
Ask at 4.6 how to change Strategies versus create a margin offset for fit if u dont use 3 shape ( fitting parameter offset at the margin its wider as scanned for better initial fit) different materials need sometimes a offset if not in the cad possible ( exocad) create in the cam.
Ask if burrs can be changed in 4.6 if you want !!! might be a long run money saver V 5 is 4 K more the strats in 4.6 are very good one of the best hard stuff anatomies if seen but maybe !!! some burr and offset options are good for better fit done in 10 seconds if possible even with no experience same with burrs just a bit knowledge.
If Mighn Voght the biggest you have problems to sinter big cases with sinter bar like ZZ the chamber volume is at the limit there is a option to sinter them laid but standing is better ( i think more consistent temperature on the hole object )
Start with the material from the reseller or direct from imes maybe some adaptions in the mill strategies done ?! chance to change in 4.6 if you use other materials ? ? different brands need sometimes small adoptions speed. step size x and step size xy
if you mill thinner margins, better approximal areas , occlusion surface all these parts are time waster and techs are interested in speed speed but the mill is your cheapest employ with loader 20 hours a day for 1.4 buck a month paid after 4 years dont think a VHF is longer alive cheap , crap long run construction.
Cam software is the key to make it real open its a bit like a electric wax knife to work with it like you want you must change temperature ( strategie) and tools ( burs ) to use all these different wax brands outside !!!
Oh forgot hard stuff never in the long run with small ball srews or without back encoders best with servo motors angulation up to 30 degrees B ax and 360 A ax 6 mm span against extrusion and intrusion force of the burr as on the 350
And although a multiboard cnc controller it could always happened especially on hard stuff that one ax fail this is a big time and money saver if happened to repair. 350 has such board.
