I'd say yes -- it looks like he's replaced threaded rod and drawer slides with wheels and channels, similar to what is used for the Z- and Y-axes on 3D printers.

Hello
Yes I moved to Vslot guides and wheels.
They are smooth and cheap. Not as cheap as drawers but they work really nice.
The problem is long ledad screws. They tend to oscillate and they introduce waves on surfaces, expecially with drawers.
Now I am planning to substitute screws with belts.

I have 15" working length on my side rails with screws and wheels without any waves in the wings. But whatever works, works.

A rectangular hole ? ...

I have seen programs being able to melt out a servo wire channel, or a joiner tube recess, or a spar recess, but can they be used to remove a rectangular section well within the edges of the profile ? Please see the attached pic for my current process, which I would like to replicate on a slightly larger winged project.

Cheers, Steve.

Certainly! As pieri70, I use DevWing Foam for design. Attached is a screen grab from the 3D visualizer of that program with a rectangular section. You can determine in the software whether you want the cut to enter from the top or bottom

Just playing around a while ago, I had it make the unusual wing cutouts in the photo below.

An extremely versatile program.

I think it's advised to add some sort of sub-rib to tie the spar into the top and bottom -- for my Shrike pitcheron wing tubes I always use at least a 1-2" partial sub-rib to anchor it.

Hello everybody
Nice to see this old thread of mine still alive!

After a long trip into 3D printers world here is my update to my original project.
Lot of custom 3d printed pieces.

Max Build volume 1500x1000x500mm, I can modify length to adapt to different wing panels.
New wire circuit with DC current and a current regulator to get constant current to the different wire lengths (hope it will work..)
Movement with gt2 timing belts and pulley decouplers
ramps 1.4 controller with DevCNC Foam By Devcad

Work in progress











A friend of mine as reference (thanks Diego you're famous now )

Hi everybody,

Quick question for the forum. Getting Theremino board is proving to be problematic, due to the Virus, Chinese New year etc. I can't even get a reply to my email from Store-ino (the sole source). I am less than happy.

My question is: will the CNC Shield V3 work with the Arduino Mega 2560.

Many thanks in advance and if the Theremino Developers in Italy can direct me to an other source. I would be grateful to say the least.

Warm Regards

With Arduino Mega 2560 the right shield is Ramp 1.4
