    Default CNC Machines for gear cutting

    I own a Shark CNC router which I use for cutting wooden gears for my clocks. I have had lots of trouble with it
    and am thinking of buying something else. Does anyone know of the OmniCam Industrial Computerised CNC
    Router 2D PLUS sold by Red Dot Machinery ? Can anyone recomend a cnc machine?

    Surprise surprise
    You have problems with your Shark. Very few don't.
    That plastic is absolute rubbish when one wants to cut something with reasonable precision.
    I have just finished remaking mine in 20mm and 10mm aluminium it is now called "The Beast"
    It works great now, I even cut most parts for the Beast on the Shark.
    Slow work but satisfying when finished.

    I am afraid that I am no fan of the Shark either.

    Looks like the one your looking at from RedDot is the same as this ebay item,

    CNC Router Engraver 500x400x90mm 24000rpm Spindle | eBay

    Seems this seller takes a hefty deposit and then imports it from China on your behalf. How does the cost compare with RedDot?

    A very quick cursory look at what is available came up with this one,

    CNC 6090 Router MILL Engraver INC 1 5K Spindle VFD USB Ready | eBay

    Add to this,
    Mach3 $180
    Cut2D $150

    and you have what looks a reasonable router and bigger than the RedDot one.

    Hi,

    Also, if you purchase off ebay, many of these routers have a controller based around the dreaded Toshiba chips. They work OK when they work, but are very fragile.

    You may want to consider striking a deal with the seller to supply the router without the controller but with the VFD. You could then put together a G540 based controller that will be much more robust and reliable.

    I sell a G540 every week or so to someone who is replacing a Toshiba based controller that comes with these routers.

    Cheers,

    Peter

    What's your problem with the controller?
    Maybe I can help.
    The software in the Shark controller is proprietary and parts can only be bought from NextWaveAutomatics in the States.

    Tell me about it.
    I have a Chinese machine I bought over 6 months ago and has never been used.
    It's a long story but the long of the short is that the seller has stopped replying to my messages and, because my 90 days have expired, ebay cannot do a thing for me.
    So much for 12 months warranty
    I have a brand new Gecko 540 and a speed controller (forget what it is called) that I won as a doorprize at the FNQ BBQ from Homann Design
    Problem is I am worried about fitting the parts into the control box I have.
    I know the Shark inside out but am concerned about Mach3.
    I have all the wiring instructions but every time I look at the thing, I lose confidence.
    Call it Old Timers Disease

    Hi MPW,

    Yeah, probably. I don't know great deal about the Shark controller. If you want, send me a PM and I'll see what can be done. It is possible that you could use a G540 along with most of your current contoller components.

    Cheers,

    Peter

    i had my chinese at the BBQ weekend, wasnt a working machine that day, i had a couple of settings issues and didnt bring the water pump for the spindle

    like others, iv ripped out all the electrics from the controller box and cabling then replaced everything from Aussie suppliers, ie Pete & Chris,
    it all looks daunting when you look at the drawings but once you get into it, its not that hard, put it this way if i can do it anyone can

    you have some pretty switched on people in your area, Russell,Dave etc,
    not forgetting members there on the forum

    one other thing, when you do get the machine up and running, get your self a piece of 10mm alum plate and bolt down to the bed then machine it to give yourself a perfectly flat bed, you can bet the orginal wont be flat to the spindle.
    cheers Tony
