It's a lot of pennies Budman68 and after what I did to her breadboard I am not sure she will even let me buy it.

One of Vectric VCarve pro's test examples cut in MDF.

Quite scary to watch this cutting as the depth of cut and loading on the spindle is very high. The finished work however, is a pleasure to look at and a credit to VCarve pro.

I had bit of a go at the Cheese Board back in February ( http://www.machsupport.com/forum/index.php/topic,4314.0.html ) and not really having learn't my lesson I have now had a go at the Bread Board.

Now, will she think that the mystic symbols have improved it or not ?.

Hi Budman68,

Now that I have had more time to trial 'Cut2D' and to be fair to Vectric - I conclude that the excessive time to pocket the 'Rocket plaque' is mainly due to the feed rates and 'ramp plunge' rates set in the example as I am pretty sure that it was intended to be made in metal not MDF. Secondary is the high number of closed loop tool paths caused by Vectric's pocketing algorithm. I just increased the Mach3 feed rate to 200% and started cutting.

I would be very interested to hear what times others have for machining these examples.

Tweakie.

Hi Budman68,

Size of MDF is 290 mm x 100 mm, size of 'Rocket' pocket is approx. 170 mm x 60 mm.
Cutter used was 3.5 mm diameter.
Total time taken for Rocket and Wheel approx. 2 .5 Hours. ( I use a low speed spindle ).

Some more of the Vectric Cut2D samples, cut in MDF.

This is one of the sample tool paths from the 'Vectric Cut2D'. It makes a very nice job but there are so many unnecessary and time consuming Z moves on such a simple plaque that I really wonder how well it will cope with a complicated design.

Another plaque for Art's stairwell perhaps ?. Neptune and Gemme / Gemme and Neptune, well maybe not.

This plaque is approx 150 mm x 190 mm and was cut in teak to 7 mm maximum depth. The cutter was a 3 mm diameter ball nose running at 3000 rpm and with a feed rate of F300 it took approx. 3 hours to complete. (The finished plaque has been gloss varnished and it was difficult to get a reasonable picture because of the reflections.)

The image is called 'Gemme', and this can be downloaded from Martin De Roode's website at http://engraving.majosoft.com/html/perfect_pictures.html.

I have posted my G-Code for this project if anyone is interested in cutting this plaque themselves. (If you use a high speed spindle then the feed rates can be increased considerably but to avoid overloading the cutter, reduce the feed rate by 50% or so for the first cut then reset to the full rate for the remainder. The X and Y zero is dead centre of the blank and Z zero is with the cutter just touching the work).

Happy routing.

Brilliant work.
