That looks wicked cool, Chris!!
Care to elaborate on the mathematically driven pattern??
I'm intrigued.

Thank you Darren.

It's a mesh triangulation algorithm driven by a pseudo-random point spread across a rectangle. Each seed point is the center of a cell. The spread can be as random as one wants, but the algorithm will always generate and even out the cells in such a way as to look connective to one another. I simply offset each cell with a radius at the corners to give it negative space to cut. Then fillet radius on the edges.

The great thing is, the structure is parametric, so once the programming is finished, I can change the density, randomness, size, fillet radius, and offset border size of the pattern by adjusting those variables in real time.

The algorithm is called Voronoi, named after Georgy Feodosevich Voronoy, a Ukrainian Mathematician who studied at Saint Petersburg University, who interestingly was a student of Andrey Markov.

Well I hope I am not the only that has no idea what you were just explaining. Way over my head. But the end product is very cool!

its look very nice. the rounded edges and paint made it look very well finished. By the way I'm using the same Voronoi algorithm to produce custom stippler portraits with good success, it's is a big hit at my art gallery.

Tom, I'm using it the old way with a command line but there are new frontends that make it easy. Take a look at the link: http://www.evilmadscientist.com/2012...in-processing/

Hey,

Anothor project i designed and fabricated on the mechmate. Had a bit of a scare over the past few days. My power supply must have spiked or something taking out my ESS. Lukily had a spare chinese breakout board that I bought for $12 off ebay, saved the day.

All cutting well again. Smoothstepper support, simply outstanding! Greg called me on a Sat and Sun night to help sort it all out and helped me to hook up the other board. What an amazing company, Warp9td. New Board coming tomorrow.

Cheers
Chris

This is Sean, one of my guys.

Thanks, it is going to be a news background.
I'm cutting an acrylic desk and was going to put a bevel on it. The acrylic is 3/4" thick, the bevel is going to be 30 degrees. Hopefully, I can cut the bevel in a few passes ok without chipping.

I just cut these cool headers out of foam core. They turned out nice. The Mechmate ESS is working well again after Greg sent out a replacement board.

I'd always recommend having on hand a spare cheap Chinese BOB. They only cost about $20 off ebay but are susceptible to noise.

Cheers,
Chris

Just squared up my gantry to near perfection. I had no idea that 1 .005" shim could make sure a huge difference. 1/16" of an in, unbelievable.

Big thanks to Greg from Warp9td for all the help he gave me over Christmas while my smooth stepper blew up. He walked me through every possible fix, then helped me hook up a temporary one. I'm eternally grateful for the smooth steppers support. It is unmatched.

Hey Guys,

Just purchased an RS-485 adaptor for hooking up my VFD to modbus and it only has 2 outputs on it. B- and A+ for RS485. How do I get this into Modbus? My VFD has R+T+ R- T- on it. Is that Full duplex RS422?

Any info on the pinout for Modbus using 2 pins would be greatly appreciated.

Thanks,
Chris

Ok, well I managed to get the Spindle running via Analoge, but not through mod bus. The only thing is that I can only get it to run very slow, and it won't go faster. There is no trim pot on the board...

Modbus, I think i need a different USB key, one with English instructions and programming, not Chinese.

What I've been making...

Hiya everyone,

Sorry I've not posted any updates for months. After building the last machine, things got kind of hectic and it was 7 days a week 12 hours a day for a couple months. Now I'm back in NZ about to embark on some NZ scenic stuff with the Auckland mechmate. So I thought I would share some pics of what I've been designing and fabricating with the OC Mechmate which is an indispensable tool to the business.

I'm constantly impressed at how well this machine cuts! These pics are for a couple studios which we designed, lit, and fabricated scenic for. Enjoy.

Talk show set, everything together.

Christ,
Love your work! Particularly the lattice partition.
How did you do the lattice design? By hand or some software generation?

Hey thanks for the compliments guys. Again, really appreciate it. BTW, my name is Christian, so not too far off I'm always impressed by the potential of this machine. I would be reluctant to purchase anything below a Northwood or Felder, or ART machine in lieu of the Mechmate. And those Vextas, man they kick arse! I get such nice cuts, they look like a laser.

I'm really wanting to get a 5 axis head on next... We shall see.

Very useful machine indeed. I'm really glad I know how to build one now.

Cheers,
Chris
