Vbit in pro sliced up project

So I get some brand new bits in and decide to use a day of easel pro to try out the 90degree v bits.
The rendering in the application looked great.
I used the stock feeds and speeds in easel since I was new to the vbits and it chewed up my project.

That looks to me like a machine tuning issue. Probably several. Go through your v wheels and belts and make sure your machine is square and trammed


Besides for the fact that you need a tuning, check the file as well for extra “ghosts”.

Also looks like your stepover is more than 1%. When using vBits set your stepover to 1%.

We know the answer is not fun and means extra work but it pays off to do it.
And check your carve depth as well.

I don’t mind extra work at all.
Seems I always have issues using easel.
I think I will stick to fusion.
Funny you mention tuning, x axis belt broke after the job. Belts don’t have but like 5 hours tops on them.

Thanks Phil I will look at it. I’m waiting on some new belts to come in. But gives me time to finish this.

there is an x controller under there somewhere.



And if it assumes .50" as the bit size for a vBit preset to 60 or 90 degrees, then 0.50 x .01 = .005" step over. :wink:

I will I did a other inspection of the belt last night and there is just not much wear at all on them.
I think I’m going to be upgrading my belts to the 9mm made by gates. We used the gates belts on an industrial piece of equipment that traverses a 300in wide sheet of paper in horrible conditions, but runs like a top belts have been on for over 5 years.


The 1/2" or 1/4" distinction is not made clear in Easel. If you choose the 60 or 90 degree selection they show, there’s nothing denoting a size; only if you select ‘other’ as I did in this screen shot. Does the width specify the shaft diameter or the width of the vBit cutting head?

Very good question! I have been wondering the same. I had been using the cutting head as my width.

A or B? Ive seen some measured like B and some like A when purchasing.

Thanks Bill, Phil is actually starting on my belt holders this weekend.

They don’t really need to since they are selling it from their “tool library”, and there are only 2 options. The other v bit is more for pcb milling/engraving. Maybe they can add all their tools in with pictures? Or allow it to remember presets, WITH KNOWN DEPTHS. I have gone in so deep sometimes as a rookie, I nearly “fixed” the machine.

Thank you!

So after some time I finished installing the new belts and tried again. Much better results.
And the machine was for sure not tuned up properly did some more reasearch and now she purrs like a kitten…thats controlled by a computer…and has a router attached to it…hmmmm…nevermind
!!! But results are better !!!

A is width
B is cutting surface (actually 0.5B x flutes)

A is what you’d use in this case as it’s the limit of surface cutting width
B might be used in some case to calculate max feed rate
