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...

Re: Y-axis Soft Limit Error

Have a look for any stray vectors on your drawing. Go to the 2D view and press F for fill screen view. You could have a vector somewhere in space that may be messing with your toolpath.

Re: array copy toolpath tool change question

Have a look at the video on toolpath templates from Vectric. This is the approach for what you want to achieve. It requires you or your cabinet software to keep your unique processes on defined layers. Apply tool paths templates and calculate. Voom there are your three toolpaths per sheet. Alternati...

Re: No Accel/Decel during ramping

Thanks Gerry. In this case the lack of deceleration sped up the production. I guess Fagor never anticipated ramping around corners at speed.

No Accel/Decel during ramping

Has anyone noticed that V-Carve ignores deceleration during ramps. I am using 8.517
I'm profile cutting with a spiral ramp four passes. All sharp changes in direction happen without the usual slowing until the final non ramping pass which behaves normally.
Could this be a post processor issue?

Re: Vac Table Top Surface

With a 5 x 12 you will need something like 20 hp of vacuum. Typically two 10 hp pumps. If they are regenerative pumps double the hp required. I recommend separating the table into zone with there own valves.

Re: Work holding

You might want to consider five minute epoxy. After machining you can release the glue with a hot air gun or torch. Acetone will remove the rest.
The problem with tape is the adhesive isn't very heat resistant. Unless you are misting the brass temperature may rise to the point of tape failure.

Re: Selecting vectors not to cut?

Can you cut the sheets upside down? Then you could mark each piece with a number and orientation before nesting then engrave and cut out the triangles

Re: having trouble with table beveled edge

Your steps leave quite a bit of sanding. That's not a problem but in future you can make the calculation of more passes for the moulding and less time sanding versus less cnc time and more sanding. There is a sweet spot in there. The moulding function is very useful and will become your friend.

Re: How to mill from the side

You can also do a series of toolpaths, profile out, while varying the machining offset. I would include a lead in at a shallow angle. You can save programming time by making multiple copies of the toolpath then edit each to decrease the machining offset. Just make sure that you check that the offset...
