I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?

This is the original C-Beam Sphinx with the 16 wheel X gantry plates. I'm using the Ethernet Smoothstepper, Gecko G540 stepper driver and Mach 4 for motion control.

Wanted a nice project to work and learn on... now have a big CNC to play with A 1500x1000mm Workbee

Started with a Rigidbot Big Added a single flat glass bed Used a Smoothieboard clone driving DRV8825

My build is based on many different builds but pieced together into a unit specifically to suit my needs. The footprint, without motors, is around 500mm x 1000mm with a gantry height of around 250mm. I used a combination of C-Beam, for the linear transmission, and V-Slot for the base and gantry supports. Forged angle connectors were used for attachment and I utilized the C-Beam gantry cart kits with anti-backlash blocks for both Y axes, the X axis, and Z axis.

This is an Openbuilds LEAD 1510, modified to supports a liquid cooled 1.5Kw spindle. The movements are made with lead screw on all three axes.

C-beam machine mods.

Two plus years in the making, I finally have a working ACRO 510 laser engraver system complete with enclosure and air filtration.

This will be my second CNC build but this time a proper CNC not a small desktop model that I played with for a while to learn Gcode, It was great but now its time to start playing with the big boys and girls.

I know this build is a little off category here at OB, but I wanted to share it with the community (as well as other coffee lovers) and show however vast the possibilities are when OB hardware is involved. This is a powered stand intended to operate a manual coffee grinder. It is compact, light, portable and uses simple drive components (B&D Cordless Screwdriver). I will post two version, V-1 (Beginner skill level ) and V-2 (Intermediate skill level). Both accomplish the same results.

A new design of my based on a couple different machines I have seen both on openbuilds and youtube. In the end will have a and X/Y workspace of 1250mm x 1000mm and a Z axis range of about 200mm.

I Like the Sphinx design thought I would attempt my first build. I wanted to build this and use Arduino controller with GRBL to be able to learn and understand my machine.

Build features include a double c-beam gantry (bonded & mechanically fastened), linear x rails, custom gantry end plates, a custom linear rail & ballscrew Z axis, and custom lead screw tensioning plates. The primary goal was to remove twist from the 1500mm gantry & stiffen the Z axis.

Building the OB Lead 1515 was straight forward. The on-line OpenBuilds assembly videos were extremely clear and easy to follow. Initial build of this machine is with OpenBuilds BlackBox which simplified getting the electronics to work the first time. OpenBuilds staff are friendly and helpful.
