ok, first up...sorry if this isnt the place. i tried searching and came up trumps.
so. im trying to cut a slot and an arc slot.
using the included angle slot wizard, i can make the straight slot no problems.
now, i then want an arc using the same xy zero point as the straight slot.
so... i plug in the xy coords, the radius of arc, blah blah. all good.
when i tap in the start and finish angles though...
first off... i type in 270 say. it decides it requires a minus sign in front of it. thats no problem. any figure over 90 and it automatically sticks a minus sign in front of it. i can work around that and figure out my coords to be in reverse...
the problem is that if i try any arc with a start and finish angle of anything other than 90 to 270, it wont generate the code. i cant get rid of the minus sign. it tells me things like arc chord length is a negative value, once it threw back an error that the tool diameter was too small...
it used to work, ive used it before (like, before i formatted my HD and reinstalled win7 and downloaded the latest mach3 release.... if that means anything?), but right now...its not doing what is expected!
maybe some screenshots will explain it better.
screenshot 1. the only arc it has decided its willing to create.
screenshot two. lets try changing that start angle...all is good, it did that. it even allowed 110 degrees to stay as a positive.
screenshot 3... my desired start and finish angles. i did NOT put that minus sign in front of 135!
and obviously, its the same g-code as screenshot2. it simply wont generate my desired arc.
i have just spent an hour or so plugging in various coords and so far, thats all it is doing. creating an arc from around 90 degrees start to 270 degrees finish, a 180 degree arc facing the wrong way... i actually want from 45 to 135.
so...is there something wrong with what i am doing here, or do i give up and go use the arc cut wizard instead? i just prefer the finish and ramp on the angle slot wizard... for obvious reasons.
