CNC611 - 3 Axes CNC Kit

Made during: genuary, 2006
Italiano, grazie!

The kit

Main features

  • Motors are included
  • 3-axes interpulated (coordinated movements)
  • 5 digital inputs for home-switches, feeling cauge, emergency stop, etc.
  • 2 relais outputs for electric tool, vacuum cleaner, etc.
    Relais contacts are accessible by 2 screw terminals. Normally Open contacts are rated 250VAC/5A. Both output have 1 signalling led each.
  • PC Connection by Parallel port. Board is compatible with practically every CNC control software on parallel port. Just to mention some compatible software: KellyCam, TurboCnc, Master5, Cenece, Ninos, Mach1/2/3, etc.
  • Single supply 12V DC. Led signalling power present.
  • All supplied goods are brand new.

What you'll receive

  • Industrial quality Printed Circuit Board (PCB)
    Green Soldermask, White serigraphy, Already drilled
  • First-quality electronic components
  • Hexagonal mountings M3
  • Parallel 25-wires connection cables to PC
  • Connectors to build extension cables to motors
  • 3 identical stepper motors
    12V, 20 ohm/phase, 1,8°/step = 200 step/revolution, Nema 23 standard mounting, maximum torque: 4,5 kgfcm, power consumption: 14W each motor (2 phases on)
  • Mach3: software for CNCing ready configured limited to 1000 rows of ISO/GCode
  • Illustrated User Manual (Only Italian at the moment - Translation coming soon). It explains how to connect the board and teaches basics about Mach3, the software.
  • Illustrade step-by-step guide at assembling components onto the board (Only Italian at the moment - Translation comeing soon)
  • Access to reserved webpages with a growing list of useful contents

What you won't receive

  • Power supply 12V 4A
    You can use an old PC power supply, which you can buy for 3 euros at electronic fears. If you plan to build your power supply from scratch, you don't need to stabilize voltage: a transformer, 4 diodes, a big (4700 uF) electrolitic cap will suffice.
  • No mechanical stuff supplied
    You are free to choose whatever you like

How can I buy this kit?

You can write me an email at: paolo (at) ideegeniali (dot) it

I sell the kit in two different versions: De Luxe (to be soldered) or Chiavi in mano (already assembled and tested).
If you can use an electronic soldering iron, buy De Luxe version: to mount electronic components on an industrial quality PCB with soldermask and serigraphy, following step-by-step illustrated guide, is fun and lets you save some money, and you may tell your friends you built the circuit all alone. If you are more capable in mechanics than electronics or don't have time or skill to solder the board, choose the Chiavi in Mano version, already assembled and tested, ready to use.

Expantions

Room leaved without components in the center part of the board can be usefully used to add more features to the board, by using a doughter board mounted on top of the mother board with hexagonal mountings. Electrical linking between the two boards can be done via a hole on the mother board which will let wires from the other side to contact right pads on soldering side of the mother board. If you impress the right torque to the wires, before soldering them, they remain on position, sticked to the board, without need to fix them with glue or other means which would realize a dirty job, difficult to retouch. All integrated circuits are mounted on sockets, for easy replacement. One of the first modification I successfully tried was to add the 4th axis, which I didn't plan at the beginning. By using the same technique, it is possible to add a 5th axis, or up to 4 more relays (a total of 6 including the 2 basic ones already present on the board). If you don't need relays outputs, it's even possibile to produce a 6 axes version of the board, as the one in the last photo on the right.

How the kit came to life

After building Rumorella (my first CNC machine) I wondered: why can't I rethink the electronic circuit of Rumorella and transform it into a general-purpose CNC control circuit, useful for anyone who wants to build his CNC by scratch or to motorize an already existent machine to trasform it into a CNC one? Target for this proposal is craftsman who knows more about mechanics than electronics, or people who do have skills to build the electonics, but don't have time or don't feel like designing and building the board by themself and would prefer finding it ready-made.

I redesigned the circuit of Rumorella in a more general fashion, I sent plans to a specialized company, who made the industrial quality PCB's. I added to the kit also 3 stepper motors, connection cables to PC, and ready-configured software, so that this offer is very convenient, and you find everything you need in one place, without the risk of buying motors from one supplier, board from another, and connection cable from a third (paying 3 shipment fees), and things don't work together once assembled. Ready-configured software, user manual, email assistance, let you use with full satisfaction the kit from the very first minute.

The kit, together with other circuits of mine, was very appreciated by hobbists and professionals of the area at the Electronic Meeting / Market / Exhibition, which took place in Monopoli (Apulia - South Italy), on february 2006, the 4th and 5th. I was at the exhibition with my little stand. Rumorella (my cnc machine) worked hard, switched on for 8 consecutive hours one day and the day after. Nothing at all got damaged: no tool broken, no circuits broken, no bold got unscrewed, stepper motors never lost a step, no added noise at the end in respect at the beginning, which is a good sign of nothing getting damaged. It was a complete success! It's a different thing, in fact, to build a piece of artwork from time to time at home, and to leave machine switched on for 8 consecutive hours while people look at it willing to find and comment on any problem which may arise.

If you find any mistake in my English, be polite, tell me so that I can correct them! Write to paolo (at) ideegeniali (dot) it
