not entirely sure about this job.. i suspect might be nipple caps of some sort.. on the mill tonight...

edit added WIP pic.. gotta love a ball endmill.. see that surface shine.. and lord alone knows why i have that Z ledge...

always does that on big cut transfers.. think my Z is funky...

may have to melt up some of me specail anaemic wax to test on.. its pretty damn solid in color.. not as translucent as the purple or blue stuff.....

hey Ken , hence the thinking on a pulsing point at much lower temps.. about 90C im guessing

@ Tweakie.. ok so then make the stepover the exact diameter of the point?

oops cut parameters

0.127mm flat profile edge cutter. 600mm/min, 0.025 stepover..

melt would be maybe 0.254mm at 0.075mm stepover? to make sure we overlay edges

not sure on this... thats the hassle with making stuff up.. nothing else to reference

you ROCK dude!

here is a typical path that i would like to use "melt polishing" on.. this is the actual cutting path at a 0.025mm stepover, for the melt polishing i guess stepover could be lower.. maybe by factor of 2?

this is that pendant jobby by the way, would require a 4th axis to do a flip or manually edit the code to do a flip at the A180 instruction.

not sure if this helps but this like i said is a typical path for most jewellers.

the kicker here will be where the path comes to the claws tat are 2mm or so higher than the rest, meaning the laser will be dwelling in the same place for longer in those areas while Z climbs the hill.. but no science is perfect.. there will always be some scenarios this idea will not be suitable to.

Mach3 under Vista / Re: Getting up and running in Vista

at the risk of getting myself scraped over the coals here im going to offer my 0.02c..

i have been through this whole Vista/XP fight about many of my cad programs already, on many different forums..


to me the answer is simple..

Mill = US$9750
CAM = US$2999
Mach = US$199

Profit per job = US$100  (in my case)

Controller PC + XP = US$150

no brainer.. everything works with XP.. why mess with it.. if it wont work with your laptop.. buy a refurbed dell unit off ebay for $150 preloaded with xp and have done with it..

this equipment earns you money, its is dedicated , it does only one job, and as such should have a dedicated pc that belongs to it? if it likes XP give it XP..

just my opinion guys
