My latest project is building a CNC Router for cutting out plywood/MDF/Aluminium and looking at ideas for controlling it.

Has anyone here any experience / views of these standalone compact CNC controllers



I have a Mach3 licence and use that on the Emco Mill and Lathe, these are in the "Clean" garage.. The Router will be shoehorned into the "Dusty" workshop and I'm looking at compact ideas that don't involve a PC , Laptop , Monitor, Mouse etc

The late, great John Stevenson was promoting the DDCSV1.1 in 2016 and hosts documentation for the RMHV2.1 on his website.

I have looked at the possibilities of using the Arduino and /or Raspberry PI [I have a supply of these boards from various "projects" ] but I feel there could be a lot of work and additional time to get a functional working system , compared to the One Box DDCSV approach.

The early versions have a 4.3" screen the latest are 5". The controllers come in 3 and 4 axis versions. 

For info typical costs for a 3 Axis controller start around £170 from China and ~ £220 from an EU based supplier.

Thanks for any input.

If you already have a suitable RaspberryPi then PlanetCNC could work for you.

I use a Windows & PlanetCNC setup and I have no complaints at all with it. I feel it would be a more flexible solution than a DDCSV, but of course you'd still need a monitor & keyboard.

Quick update


I had come across the Madmodders earlier and read 40 pages on the DDSCV  till the early hours !


I've also poured through the Facebook pages for the DDSCV , seems popular in Latin America !!

There is also a useful web site with firmware, manuals and configuration setup info

I have ordered a unit ..., now awaiting delivery from China .

The fun starts in about 2 weeks time. Should have the frame and hardware workable by then

I have had one for the last 3 years or so - they are great in that they are self contained and dedicated unlike the full PC and associated technology required to run Mach3/4.

Downside is that you have no access to wizards or simple CNC operations apart from 'manual CNC' using a handwheel.

My intention is to upgrade to one of the more sophisticated (and expensive!) solutions that include conversational solutions so that e.g. a simple surfacing operation doesn't require a dedicated CAD/CAE exercise.

Benedikt at Pandora does a sterling job, well worth watching his site .
