On the left it says Mardus (Marić Dušan) - Kreutz

Looking for some drives to start off, I found those and discovered that I met Mardus some years ago. A phone call and I was at his house to discover his adventure about learning how to build a powerful stepper drive. Along with Kreutz on cnczone they planned and released schematics for these drives.
These drives were used on my first smaller machine and also on my MechMate for 6 months. when they got replaced with bipolar drives, for cool running and more torque. Recently my friend developed a bipolar MardusKreutz using L6203 chips, its still in testing but will run his mechmate when its finished.

In honor to my friend Mardus I put that on the left side of my MechMate. Of course regular Mechmate decal is on the right

I also made these huge numbers and a small house for a play "Mileva Maric Einstein"

layers were assembled with pegs and LED lights installed inside, foam/plywood so they are light and can be carried around with ease in the show.






Mechmate cutting these numbers

These two years making and working with Mechmate were great, and I hope that with gaining experience I could return a favor to community!

Some nice Vcarving, for me this is the easiest technique of creating artwork. For these I used parts of vector drawings and some of mine elements. As always anyone wanting the artwork, just needs to ask

Yes I use Aspire, but as I mainly do 2D any cam would be sufficient, just got used to aspire. Must say that sometimes with large number of vectors, curves and points its slow on trimming even with a newer computer.

Do you use a vector graphic program to create prior to import files into Aspire ?

Autocad always, for any geometry and designing construction parts from simple "how should it look" drawings. Then import in aspire and join, trim as necessary.
This logo was imported from AI, Adobe Illustrator, very nice feature in aspire to import AI directly.

Also I always use the aspire feature, curve fit vectors, to convert all the curves to Bezier curves

I only get an evaluation version of Aspire two days ago, I don't know all the features.
Aspire looks like a very complete program, production ready with it's excellent "automatic profiles" feature.
Does Asprire replaces(include) all the other Vectric programs (Cut2D/3D, VCarve, PhotoVcarve...)?
I agree importation features on Asprire are great, I'll be able to import 3DSMax or Rhino files too.
I use those programs Since a long time, as Illustrator as well. Great because I'm not as good with Autocad...

Look here for comparison, only Cut3D and PhotoVcarve have features that Aspire has not.

2mm DOC and about 1.8m/min feedrate , nothing special. I had some pretty durable cutters, they refused to break even when some pieces that fell apart hit them.

doing some kitchen fronts, and doors carving... I had to make some sort of a hold down.
This removable table worked like a charm.

I had a couple of issues, Y axis constantly was 1-2mm off after the gcode ends. So I repeatedly zeroed it again, checked for mechanical slop but there was none. Only to find what I have found in the past.
While testing some other motors couple of weeks ago, I set Mach3 kernel speed to 45khz. Last time I forgot to put it back to 25khz I had the same situation with X.
So smack on the head and revert to 25khz, problem solved!

Danilo. I too rarely set a machine in the 45K kernel speed.
For whatever reason - bugs pop up at that speed on some motherboards.

Some more Vcarving, it amazes me how fast it is produced and how nice is the effect.
