DIY Machining center development

Jan Henning — Sun, 29 Jan 2012 02:25:46 +0000

The Arduino board, that we know from many multicopter projects, is used to control this 4th axis. This is a video posted by Steve Simpson on YouTube. This is the same 4th axis I have for the BF20 mill, and it’s very nice to see how Steve continue to expand the possibilities.

“here is the long needed custom 4th axis motor controller. Designed specifically to take full advantage of the unique capabilities of the ‘mini machinign center’; which is a normal mill fitted with one of my 4th axis”

Open Source Multicopter Controllers

Jan Henning — Wed, 13 Jul 2011 00:49:32 +0000

If you search for the latest in affordable flight controllers, there is no way around the community projects. As an open-source project, all source code and hardware plans are freely available for anyone to produce, use, modify, and redistribute in accordance with the GNU GPL License Agreement, which requires only that the open-source nature of the project must be maintained by all who redistribute it. These are the products that will take over the DIY multicopter market for sure.

Today I received the Open Pilot CC board, which is the first commercially availible board from the Open Pilot team. I had the software installed allready, and after hooking up the board everything came to life without a single problem.

The CopterControl platform has been designed to perform the following functions:

a MultiRotor controller with auto-level, including TriCopters, QuadCopters and HexaCopters
a Flybarless Helicopter controller with auto-level
a Fixed Wing UAV controller

The CopterControl hardware has the following features:

Powerful STM32 32-bit microcontroller running at 90MIPs with 128KB Flash and 20KB RAM
3-axis high-performance MEMs gyros and 3-axis high-performance MEMs accelerometer
Tiny 36mmx36mm 4 layer PCB for superior electrical noise reduction and flight performance.
Software support for Windows, Mac and Linux
Direct high speed USB support with no drivers required, a truly plug and play device.
Spektrum satellite receiver support
Futaba S-BUS hardware support
Innovative Flexi-port technology for superior port flexibility
4Mbits on-board EEPROM for configuration storage

A detailed review will follow when the mikro Y6 is ready. This looks very promising!

Development of the Micro Raven 140

Jan Henning — Sat, 18 Jun 2011 20:10:29 +0000

I have always wanted a really small UAS, and since the Raven 740 worked so well, I decided to bring the same airframe down to micro size. It’s still in the early stages of development, but I have gathered most of the parts, and the last piece of the puzzle will be the OpenPilot CC board.

On the hardware side I have been inspired by the great performance of the Shrediquette Bolt, so there is a resemblance in the power system.

OpenPilot CC controller
NMEA complient GPS
Futaba FASST radio system – S-Bus
Robbe and DragonPlate carbon materials in frame
6 Robbe ROXXY BL Outrunner 1815/25
6 10A ESCs
AirAce 3-blade propellers
3 cell 1050 mAH LiPo battery

I wish to set up a 4th axis on my mill, and this build is a perfect excuse for me to finnish that project.

I will also try a version built up from plates (1st picture) with protected propellers.

Preview of the new Y6 design

I have flown the Okto for 1 year now and it is time for an upgrade. There are some nice frames on the market, but in the end, I decided to design my own.

High speed spindle for the BF20L

Jan Henning — Thu, 27 Jan 2011 20:54:27 +0000

Some pictures from last nights project. I have to mill some carbon fibre parts next week, and the 3000 rpm I got on the BF20 is way to slow for the small endmills I plan to use. The Kress 1050-1 has 5000-25000 rpm and I think it will be a valuable addition to my machine. I’m looking forward to explore engraving and some fine detail 3D aluminium work as well.

BF20 Machine Enclosure

Jan Henning — Mon, 10 Jan 2011 18:04:39 +0000

I have finally started to build the enclosure for my BF20L mill. The BF20 is the same mill as the Grizzly G0704. There are some small differences, but they come from the same factory.

I am going to keep the original Optimum base as is, and modify a lathe stand from an old Boxford for the enclosure. Dimensions will be W:150 x D:80 cm and the top will be open.

4th axis for the BF20 Mill

Jan Henning — Wed, 05 Jan 2011 14:50:44 +0000

I have ordered a 4th axis from Steve Simpson. I first became aware of the product when I saw it in a forum post at www.machsupport.com It’s a versatile unit that can be both 4th axis and lathe. Mine is ready in a couple of weeks, and I can’t wait to test it.

The product have gone through several design changes since I first saw it on YouTube. It has been a fun process to follow, and the result of the evolution is amazing. I went for a heavy duty version with 2 step belt reduction and pneumatic brake. Max RPM in lathe mode will be around 3500 with 1:1 ratio in 2nd gear. I have decided to use a Yaskawa 750W AC servo in the Sigma II range. The servo setup seems easy enough, but I have only tested it with the RS232 interface. As a 4th axis it will be controlled with Mach3 and position control with step and direction signals from a computer.

These machines are hand made in batches, so you have to contact Steve for details. His website is: www.thecubestudio.com You can also check out his YouTube channel for more videos.

Expect a follow up when my 4th axis arrives!

Amazing video shot with AP multicopter in Spain

I found this great video on the homepage of Photoship One. Juan Jesus Fernandez of www.helifilm.es has made an amazing video with a mkTR camera gimbal on an Oktokopter. Enjoy!
