I'm stumped, what are the character families you have engraved?

Re: vacuum tables

I have a 7 1/2 hp vacuum pump made by Buusch. It is relatively quiet, less noisy than my dust collection. I wouldn't be without it. I route full sheets often and the pump will hold pieces down to 20 sq. in. in place when cutting on a freshly decked spoilboard. I have made gasketed melamine jigs to h...

Re: Feed rate drops at dogbone

My theory is that the dogbone fillets are of different radii. When the radius of the dogbone is very close to the radius of the cutter then the control software calculates a very small radius arc and the deceleration is large. If you draw the dogbones with a larger radius offset then the arc will be...

Re: I would like your opinion

Slow down the rpms on the spoil board surfacing. I'm running 450 ipm at 6000 rpm and the inserts last for 6 months or more of surfacing. I was blowing through inserts before when spinning faster.

Curious corner cutting

It took me a while to get my head around this. I was cutting a series of nested frames from sheet goods a while back. The toolpath was profile outside of vectors. All right angle corners. What I noticed was the cnc came into some corners and made a slow dwell at the apex and then resumed cutting whi...

Re: sometimes your lucky

May I suggest adding weather strip (brush type) all around the pocket door to keep the dust out of the photography area? It will get in there anyway but every little bit helps. I'm jealous of the new clean and tidy work area. Mine has twenty years of accumulated dust and offcuts.

Re: How can I cut circles without creating projectiles?

I have had good luck with a last pass allowance and the final pass depth of .050" or less. I would try a last pass allowance of .025" or a little more. Ramp in. The allowance will keep the bit away from the center loose piece and the light final depth imparts minimal load on it.

Re: Very basic question about tooling

The line with arrow is the recommended minimum insertion into the collet. I don't know the bonus answer though so I guess I don't get the free toaster.

Re: Odd Oval Shape

The fluting toolpath will be quite complex to setup for this job. The program does one simple thing, for this project it will cut on a vector starting at one depth and plunge steadily to another. To set up fluting paths for this job you would hav an array of parallel lines quite close together repre...

Re: How do I nest faster

I totally ignorant of the workings of the the nesting engine but would the number of nodes in the vectors slow the processing? Have a look at your vectors. Can you reduce their nodes? It might improve the speed.

Re: Dust cnc makes a lot of it

The fine dust from the cnc goes to mechanics and machinists for oil absorbant. The shavings from the planer and jointer etc go to rabbit and chicken farms. I only throw out dust that is contaminated with plastic

Re: Cam question, removing perimeter of circle, for example.

Your final shape is a circular isalnd in the centre of the square workpiece. The not so efficient but easy to draw toolpath would be to draw a series of vectors (circles) around the final profile spaced apart by the pass width desired for your cutter. You then select each circle from the outside inw...

Re: Cam question, removing perimeter of circle, for example.

I don't think that V Carve has that toolpath ability built in although I would like to have that for machining solid wood. If you are not concerned with speed you could draw a series of concentric circles representing each pass and profile toolpath using vector selection order (adding a small lead i...
