Testing some rc servos

Posted by | 6 axis CNC / robot prototype | 2 Comments

Just as a quick update to the last post, here are my servos for the prototype… basically dancing at the whim of my computer!

For those interested, I’m running a Mini Maestro servo controller (by Pololu), using the supplied sequencing software. This took about 5 min to program.

Enjoy!

Another project begins…

This one has been in the “still dreaming” phase for about a year, but a few parts are finally starting to arrive, so I thought I’d share a photo.
These parts are going to become a prototype of a 6 axis milling machine/general manufacturing robot which I intend to launch one day as a low cost/open source alternative to the current expensive commercial offerings.
Up next, a video of these being tested – Keep your eyes open!

Update on the mill

During the last 2 weeks I have had the chance to do some work on the mill in my new workshop. With my brothers help I have managed to build a good solid 1200 x 2400 steel workbench, and have started construction of a pedestal and frame for the X3 mill.
All controller components have now arrived, and construction of the controller housing has begun.

First brushless motor test

This motor arrived yesterday for the electric scooter I have been working on for a while.
Hopefully the next video will be more exiting than this one!

[Edit] – I thought I should add some useful information, so here it is!
This motor delivers 1.5kW continuous and 3kW peak at a maximum of 35,000 RPM! It’s rated for 42 volts, but my scooter will be operating at 33v, so I will be limited to about 1.2kW continuous and about 27,000 RPM. Still not bad for 10kg scooter!

CNC bits arrive!

One of my hobbies is making CNC machines (as of today!), so I was excited to receive the box of hardware needed to turn my X3 mill into a 4 axis CNC machine. I have been researching this build for about 10 months, so to finally have the bits in my hands is pretty satisfying.

The hardware kit I went with is from a company called Promica, run by a guy who builds all the kits on a machine he has converted with one of his own kits. Very impressive.

Photos will follow…
