What am I doing wrong?

[Simops]

Ok now I know what you mean Adrianm in your post 25 above!

The spindle control window now appears as soon as SB3 starts (by changing the parameter to 1 for 'start when SB3starts') and now when I run the warmup routine or cut file the spindle goes to the programmed RPM.

So the spindle RPM window needs to be running in the background every time SB3 is running for the spindle to work automatically. I was not aware of this and no matter how hard I try could not find this documented (probably is but it alludes me)!

All good now and at last I can run feed rates higher without breaking the bit

Thanks for your input...

Cheers

Mike it isnt in any literature in Buddies sent ot Oz as both Russel and myself had exactly the same no rpm change problem in our machines which are only a few months older than yours. Neither of us have ever broken a cutter (specialise in hitting screws instead!) as we are both metal machinists and 6 inches a sec are unheard of in metal. I prefer downcuts as they put less load on the hold down method. In case you have "strayed" from using Onsrud bits we tried Carbatec and that other one in the yellow packet (seniors moment). They are nowhere near as good and you get the dreaded screaming. Garry Becker on this forum sells Onsrud and you get them in a week. Amazing guy - no matter what time you email you get a reply in an hour! Also great for 3D graphics. Suggest you get a spare 1/4" collet as these only last a year and you can get cutters walking out in hard wood on heavy loads particularly Spotted Gum.

Still waiting for your helicopter to land in the back yard. Should I mark out a big X?

Hi Bob,

Yep already bought Becker's 3D cutter set. You are right got it no time.

I also have a spare 1/4" collet....so good there. Plus I purchased a 1/8" collet as well as I have some 1/8 bits for some ally work....but haven't tried it yet.

Onsrud bits seem the way to go.....what about Carbi-tool.....their manufacturing plant is 30 min from me and they have a compression bit I've been eyeing!

Hey I flew over your place a couple months ago but you must have been to engrossed in your shopbot to hear me

Cheers

Would that be Gary Beckwith?

Yes, that's correct.....BDP cutters....
