I will be attending the 2017 Midwest RepRap Festival (MRRF) with a small team of printer enthusiasts with a goal to fully assemble a Core-XY D-bot onsite during the event. This is our first attempt at building a D-bot and we will be learning things as we go. Our hope is to have the entire machine assembled, wired, and functional (at least to the setup and testing phase) before the end of the show. Please attend and watch us in person or visit our feed channel during/after the event.

Hypothesis - Running CO2 laser tubes at high amperage may shoirten tube life in number of hours, but will be made up for by the increase in actual inches engraved/cut using the higher power. This is a long term experiment, so the build status will remain as "Build in progress" until the experiment has been completed.

A cartesian build with a build dimension of 200x200x750mm. I will be using a dual extruder, heated build plate, and a screw drive for the z axis.

An Openbuilds replacement rail system for the common eBay "K40" C02 Laser Cutter

I have the demand to cut/etch tall pieces of material. For this reason, I have designed a machine with 500mm uprights with adjustable gantry height. This way I can raise/lower the sled and z-axis as needed. I've also chosen to use a linear C-channel assembly for the Z axis with the plate mounted to the gantry instead of the other way around. This will allow for maximum range of the z-axis. The parts list/BOM does not include motors/belts/pulleys or electronics.

4foot by 2 foot, 10W El-Cheapo blue laser

Heavily upgrading my 1200x500 Shapeoko 2... ...er, wait, scratch that... Building an all new machine, roughly the same size, that should be more rigid than a Shapeoko 3!

A copy of the Stainless Ox by Martin Barfoed. Similar design, construction and control.

Acro based 2 watt laser platform

I will write a short buildlog here with mostly pictures. I designed this lasercutter in solidworks(not totally finished) for a good overview and such that the steel tubes could be lasercut by a company, the metal frame is based on the lasercutter the KÄSER, which you can find on cnczone.nl. The mechical parts are designed by myself because I had no mill to my use, so the mechnical parts are lasercut(same company as tube) steelplates welded together.

I ordered the OpenBuilds MiniMill from the OpenBuilds Parts Store http://openbuildspartstore.com/ They were out of Motors and Electronics when I ordered so I had to source these items elsewhere. But it turned out well doing it this way.

Somewhere along the line sometime around February 2017 I got the bug in my head that I needed to build a CNC router. This is where I am today...

Some enhancements of the basic mini-mill

Theoretical Working area: 38" x 24" x 6" Actual Working Area: 31" x 23.6" x 4" Positioning Accuracy: about 0.01mm

I got lucky enough to purchase aluminum extrusions and linear motion components (and nuts/bolts/etc) at scrap metal prices when a bunch of industrial automation equipment was decommissioned. The only problem is that the aluminum extrusions are not metric sizes... they are the 1.5"x3" 80/20 series. It has presented a few challenges but nothing too bad.

Mad plumbers choice what Else can i say?

More stuff here.

Contained within are links to our OpenBuilds sponsored C-beam Machine live build taking place at MRRF 2018 (Midwest Reprap Festival) on March 24 and 25, 2018. There will also be some build images and a few 3D printed STL items that were added.

The Acro Laser Machine Build

Hoping to build a WorkBee 1000 x 1000 (2000) from parts and not a kit, cannot afford the kit in full so going the long way round...

Build Notes: Here are all the parts necessary to re-produce this design. Please note, all of the parts are either sourced through openbuilds or have been selected and printed from thingiverse.

This OpenBuilds C-Beam XLarge X/Y Table is a great display of how easy it is to modify and create awesome configurations with the OpenBuilds system!

This easy to build and effective system can take your builds to the next level! This design is strong and accurate and could be the solution/upgrade that you've been looking for!

Building a CoreXY based 3D printer using primarily parts from China on eBay. Large 500mm frame.

This build is based on the Workbee 1010 CNC. It is not a kit build and is much the same as the original but with some significant changes made here and there as the build progresses.

This was my first foray into CNC. I chose to go with a reliable kit build since my knowledge of GCode, controllers, and steppers was pretty rudimentary.

DIY design and build of a roughing 2' by 3.5' CNC router

This is a lead 1010 build that I wanted to have a little fun with. I purchased the whole Lead 1010 kit, and felt like studying a few shortcomings of the original to see if I can improve it or just have some fun with it.

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.
