mardus kreutz are open source stepper drives

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 :)

Thanks... I found the thread on cnczone. I've done some research on drives, but never heard of this.

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!

Aaaand a bunch of these "I don't know what it is" parts. Cut from 30mm thick PE sheet 1x1m , around 163 parts from that sheet.

Danilo:

Thanks for the update. You have inspired me to get cracking on a number of my own projects.

I would make a very nice marbles labyrinth with them :)

Well they were all gone the next day when I delivered them, next time I will surely make a marble game out of them :)

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 :)

Nice ideas and nice work Danilo, have you still got my e-mail address? :D

Very nice and I think you should have my e-mail handy...thank's

I will get it from you oak`s:D

Hennie, you mean okes, not oaks. It is a shortened version of blokes. :)

Danilo:

Thanks for the photos. Great work. Inspiring.

For all of you interested in files here they are. Aspire 3.5 files and EPS vector export

www.cnc.rs/mechmate/carving.zip

Very nice carving, I love the leafs :)

1200mm central logo , 10mm birch plywood , done with 2mm endmill, some parts of letters are not on the picture. It will be backlit trough 3mm opal acrylic oval 2800 x 2000mm
with a back structure like rays. Will post pictures of it when finished

Looks very nice.
Always with Aspire, I guess ?

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.

Hi Danilo

Your carving backlit with rays coming out of it, we have to see that !

Ross

Hy Danilo !
May I ask you, when time permit, share some of cut settings for this nice work with your 2mm cutter ?
I have not yet tried nor practice some cut with such detail work nor with a 2mm cutter !
I’m quite curious to see what consideration are made !!??
Thks in advance.
Amicalement, Robert ;)

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.

Beautiful stuff Danilo.

Very nice work, Danilo.
I've just purchased aspire 3.5 and spent the weekend watching tutorials.
How long did that huge arch top piece take to carve?

51min , its 1000x500mm

Danilo car si,the best.

Nice work! Inspiring.
Looks like poplar but I know in Europe they use a different name for it.
Pappel in Germany...

Tilia is a genus of about 30 species of trees native throughout most of the temperate Northern Hemisphere. They are generally called lime in Britain and linden or basswood in North America.

Thats the wood. Its very nice for carving but lacks texture like ash or maple.

Danilo - outstanding - can you post the pic from where you have derived the vectors.

would like to practice some beautiful work myself.

And here is the final piece, crown for the top, and a batten which goes below it and on top of the arch piece.
More pics to come when it gets assembled.
