The machine is all up and running. I can do anything up to Aluminum at the moment but am going to look at cutting steel in the future.

I am looking at selling CNC parts so feel free to PM me if you want something made and I will let you know the cost. Or if you require something from shapeways I can 3d design the part for you.

I am also looking at buying some of these Parker solenoid valves, but I need to buy them in bulk to save on the postage, would anyone be interested in one of these valves if I bought them?

An old anticipation support from HDPE:

I might have another valve if you're going to order a few, did you get through to Parker?

Hi Andy,

I'd probably take one of those off your hands. What's the cost?

Hi Rhys

I am looking at selling them for £25 each, plus a little bit to post them as they are so light.

They take the same size tube as the robart equipment available from technobots. However for a lighter ram and better flip a lego ram could be modified to take the smaller pipe.

Its been a while since I last posted, I have been building a full pressure flipper using my milling machine. I will post pics when I have more done. However here is the 4th axis upgraded and turning:

Also this is the machine cutting some HDPE like butter

Look for some new silly robots in the next year.

New CNC project!

This is going to be good!

Awesome. Will be interesting.

Will be watching this with interest

I have been working on this mill until I have some new ideas for robots. It is now up and running although there is a bit to much backlash on the X and Z axis, Y currently has 0.035mm 8)

It took about two weeks to make the parts to mount the ballscrews and bearing blocks (Ebay). I also had to modify the base to have 2 more screws hold in the Y fixed end support and had to drill out the top of the column to hold the motor supports.

X Axis:
Fixed end support
Floating end support
2 stand offs
Motor Support
Ballnut adaptor


Y Axis:
Fixed end support
2 stand offs
Motor Support
Ballnut adaptor


Z Axis
2 stand offs
Motor Support
Ballnut adaptor (although I had to make a thick shim as I measured this wrong)


I mounted the drivers (motioncontrolproducts) and power supply (cnc4you) into the PC I was running on the old mill and put this on a shelf to keep the swarf off.

I got the vice today, 4" wide and opens to 4" so billet antweights are possible The problem with the X axis was flex in the ball nut support so I made a new piece out of Aluminium to see how the new machine compares. I was cutting twice the depth, double the spindle speed and almost tripple the feed rate so six times faster to make this part than it would have done on the old one.



Defiantly gets a shiny award



I took a video of it going but its not very interesting to watch. I will have to try some steel over the weekend.
