Wobbly: my first 3-axis router

[Sodster68]

Hi guys

My goal with this machine is to be able to make parts in thin plywood and composites. First project is a gyro stabilised camera gimbal mount for my quadrocopter.

Detailed design is finished. Parts are beginning to arrive. I understand using ground axles for linear motion increase the risk of resonance. So I came up with the name 'Wobbly'!

Drive is through M12 threaded rods with anti-backlash nuts. In an attempt to unload motor axles I intend to use thrust bearings and lock nuts to support the rods in the frame.

Dimensions comes from using available cheap(er) parts like axles of a given length et cetera. Frame parts are MDF.

It is a prototype and the idea is to make all the electronics and logic work in a simple machine before moving to larger sizes and better linear motion.

Hope to start cutting MDF parts in a week or two. As usual, build start slipped a couple of weeks since parts are a little late...

What do you think?

Cheers
Patrik
