Hi Sam,

Happy to help. If I get a chance I'll try and do a high level schematic, it is fairly straight forward. I suppose the most complex part was the Emergency stop system. I was not happy with the idea of just using the e.stop on the controller pendant - which is basically a software halt. I've added added Full E.stop system in that kills the power to the motor drivers and spindle, and it also sticks the controller into e.stop as well.

90% of the parts came from Amazon or Ebay. The spindle and motor drives are the cheap clones, I always planned to upgrade these later if required however they have been as good as gold so far.

The DDCS controller is basic bit does exactly what I need. I didn't want the hassle of PC's and dust etc in the workshop so opted for a dedicated controller. I use Fusion 360 to do my design work, there are post processors for the DDCS controller you can download and install, they work well for me.

One modification I'd recommend was to the X-axis gantry rail. If you look the only support the Z axis carriage has is the linear rail itself. I got a piece of angle iron and bolted it to the back of the linear rail and to the two side supports. This stiffened up the X axis massively, and I now get a lot less chatter, and deeper cuts! It's a £5 mod!

I can cut plastic, plywood, MDF and Aluminium (slowly!),

I'm going to fit a larger spindle in the new year, I'll post some updates when it's done.
