Ok what am I doing wrong?
I have d/l'd the files and open them in Aspire 3.5, I look at the tooling used and had to change them to what I have.
1. 0.25 End Mill (Flat 2 Blade)
2. 0.125 Spirel 3 Flute Tapered Ball End

I have them set to:
21000 rpm
85 ipm
plunge rate of 30

I am using aspin for the wood
What I am see is alot of tare out and waves in the cutting. ( if you look at the vain in the leafs)
I am running this a a Legacy CNC Woodworking's Arty 58"

Thanks

Hi,
I would test on a scrap wood, start alot slower than you stated, I am not familiar
with the machine you describe, but is this an often used machine by you?
If it is new to you, have you checked it for mechanical issues...backlash,loose ball screws,
stepping motors losing steps? with it turned off, (for safety sake), can you force the
router up, down, or any direction?...if so, this movement must be eliminated to have a good cut.
If your machine is good and tight, then maybe what you describe is the actual bit
being too large for the job. Maybe resulting in the waves you speak of.
When you changed the tooling, did you go with a bigger tool than the original called for? If so, you may have to blow up the size of the model in order to have the bit reach in the crevices of this model.
curious to see how you are doing
Glenn

Thank for the reply, I am using scrap wood for test the cuts, I just got the machine early this year, I am using the same size of bits, just different type.
The owner of the company check out the machine and made some adjustment on it, all is good there.

I guess the big problem is not knowing what to do at this point.

What does changing the plunge rate do for me?

Thanks for the help guys.

Check your stepover setting. I usually run 8 to 10 percent on a 3d finish toolpath.
