    Default The order has been placed - The beginning of a custom Torus Pro

    Well I finally pulled the trigger and wired the money to Novakon last Friday (the 5th) it shipped yesterday (8th). Now I have 4-6 days of waiting for it to show up.

    As the title leads on, this is the beginning of a customized Torus Pro build. I special ordered my machine without any axis motors or controls in the electrical cabinet. While this may seem crazy to order a turn-key machine to not be turn-key it was the idea thing for me. I just do not have time right now to take on a "from the ground up build" and I could not justify buying a complete turn-key machine only to rip out all the things I wanted to do different. I work as a machine and controls designer by day, a college student by night, and an IT guy by the weekend. So fitting some servo motors, wiring the controls, and setting up the software are going to be the most fun parts for me. I am not sure where things will end up when I am done but in the "big picture" this is the tentative plan.

    1. Get the mill running in a basic form where I can make the parts needed for the next stage
    2. Start the design work for a new headstock to utilize a BT30 automatic tool changing capable spindle and a 3 HP 8000 RPM spindle motor
    3. Design a automatic tool changer for the mill.

    So far I have on order
    -Mill
    -Spindle cartridge
    -Draw bar release cylinder

    On hand I have
    -3 HP continuous 5 HP overload for 15 min, 8000 RPM Yaskawa spindle motor (for later)
    -Hitachi WJ200-055 5.5 KW VFD
    -Most of the relays, fuse holders, misc controls stuff

    I still need
    -Leveling casters
    -CNC controller
    -Servo motors
    -Free Time

    Cool that is almost exactely as i Do. Only different i use European built Mill. My picture is to have a shrinked Bridgeport 4 12 which I right now refurbish on servos ...

    I am interested to see how it goes.
    I find the controls and electronics are a sweet part of my Torus. Nicely done really. That BT spindle should be something to see for sure. Lots of guys are interested in those.

    My beef with the controls is the parallel port based connection. It is a greatly aging interface that is nearly gone. I am going with the KFLOP which has its own processor for better control. I know it is a small detail but it is just what I wanted to do.

    The BT30 spindle is my biggest worry now. I have not heard from the vendor in a week or more. It is supposed to ship any day now but I do not know if it will be.

    That is understandable. I know a move away from PP will be coming and probably sooner than one might think. It is certainly on the way out. I haven't yet decided which way I will go when the need arises. I know the availability and utility of alternatives are getting better every day though, so holding out may be the prudent choice.

    If you mean an add in PCI card, yes that would work to add one to a computer. But that does not change the fact that is it an interface that is being used for something it was not designed for. To use a parallel port you are relying on the PC to be a realtime operating system and keep the timing of all the signals through the parallel port perfect. This is something that the PC and the parallel port were never intended for. Does it work on 100,000's of lower grade setups where a little miss timing is ok, yes. But there is a reason full blown CNC machines do not use a parallel port for running their servos. On an industrial machine the control of the servos is handled by a motion controller, in the form of an expansion card or external box that gets data from the computer. The motion controller takes the move data from some source (PC in this case) and does the processing to coordinate the moves and keep everything perfectly timed.

    In the hobby world we generally have 2 ways to interface a PC/computer/tablet with the CNC machine
    1. The simple "Break Out Board" - The name I assume comes from the fact that the original ones where just that a board with a connector for the parallel port of the computer and a bunch of terminal blocks to connect your drives to that correspond to pins on the parallel port.

    2. Motion Controllers - These have a standalone processor(s) that is feed information from the computer and then it does the processing and generates its own signals for commanding the motor drives. These seem to come in varying levels of sophistication. Some are nothing more then multiple parallel ports without a connection to a computer so signal timings are closer to perfect (USB and ethernet Smoothstepper). Then others can take in many signals, read in encoders and fully close the control loop for a true "closed loop" system. An example of this type of motion controller is the Dynomotion Kflop. I beleive this is the truest form of a true motion controller I have seen for the hobbyist/ amateur market. I am sure there are others but I don't know about them yet. In industrial controls there are many more advanced motion controllers availible but most of these I have seen are in the "thousands of dollars" price range and all they typically add is more processing power and more I/O.

    In my research into this I feel the kflops controller is the best bang for the buck. It can run with mach3, but it also comes with its own (kinda dull looking) CNC controller software for free. Dynomotion also offers several expansion carts, maybe better called adaptation cards. These cards give you added I/O capacity and expanded functionality to the KFLOP card. There is a downside to all this power and flexability, it is not the easiest to setup and it can require some computer programming. Additionally I have not found the documentation to be written for the beginner, I have had to read most of it a couple times and I have been working with industrial controls for many years. But for me I feel this card is a superior way to control my mill vs a parallel port driven "breakout board" and I feel it is worth the time and effort to learn the hardware and software.

    Dan,

    I hope you get your stripped Torus Pro soon. I'm looking forward to following your CNC build.

    Are you on the east or west coast?

    I am looking forward to the call from the freight company very much. I have to assume I will have my mill by Wednesday of next week.

    I am as far away from a "coast" as possible, unless you count Lake Superior. I am in Minneapolis MN.

    Well I got a little surprise tonight, one of the guys at my friends machine shop sent me a text telling me my mill arrived. The surprise is the freight company never called me. I only had enough time to swing in and crack open one crate before we had to leave. Tomorrow morning I will head down and uncrate it all.

    Here is the option we went with to move away from the PP. Simple, easy and it comes with Mach software although in a much cleaner GUI. No learning or programming in C or C++.
    Have a look.Industry Controls
