We just had to switch to a quadro style card because I was having alot of problems with the geforce. The problems primarily were with solids. So keep this in mind if you use solids.

I have seen many a machinist try to be toolmakers or moldmakers and it doesn't seem to work out. They can't understand why it has to be that perfect.

I cut hardened s-7 and h-13 as well as graphite all the time on a creative evalution. For the the money you can't beat them(just over 100k compared to Makino). 30,000 rpm and incredible finishs. Check it out at creat.com

.001 should be ok. A two flute is usually best on small cutters because it is stronger and has more chip clearance. And I agree with hardmill Jabro and OSG both make very good small cutters. I use them all the time in hardened material down to .3mm dia.

I used the tried and true trial and error method to get it adjusted. I would just hit e-stop as it was going in for the change and see how much it moved then adjust that value as best I could then try again.

It should be parameter 64(tool change offset). There is a formula you will have to play with. I have done this before and it isn't to bad. Just a little trial and error.

At graphite speeds it seems to have always been this far off. But I cut some hardened material today and it seemed pretty close.

Yes, that is a good suggestion. But in this case there is a tangent radius so the side wall isn't the problem finish is my primary concern. The part is the cavity area of a mold. It is also hardened so any little whip of the cutter tends to leave a visual mark though it is usually not measurable. I'm just trying to save myself any bench time if I can.

I believe your correct. But I am trying to machine a floor. I believe that is all horizontal will do.

I'm trying to use it in the new high speed horizontal toolpath that came in MR1. Have you had a chance to play with these new toolpaths?

No, I'm using a 5mm ball tool. But, as I understand it, it should be applying this in relation to the tip not the perimeter of the tool. I did try increasing the rad. to .25 and it had no affect.

I am trying to use the new high speed horizantal and don't want the cutter to slam into the corners. So I selected toolpath fillet and entered .050 rad.. It isn't showing it on the backplot. Am I not picking something or is this something someone else has noticed?

Pete had me disable the hardware acceleration box and it seems to have fixed it for now. Thanks for the input.

Pete I sent you a different file to try that I had problems analyzing.

It seems to happen after I have put a tool path on it.
