Why no Mach 3 support for 64-bit system?

[sgalway]

Newbie here just trying to figure out all the ropes. I realize this question might be a little vague. Exactly what software do I need for my CNC conversion?

As I currently understand it I need the following:

1.) Some form of 3-D modeler (I currently use Rhino and would like to continue)
2.) Some form of G-Code converter (I understand Mach 3 is a good choice)
3.) Drivers for Windows?

Can I develop the G-Code and control the mill from within Rhino?
Is there some software in which I can model and control in the same package?

From what I can gather, Mach 3 is the preferred choice for drive software for a benchtop CNC mill. I noticed they don't support 64-bit OS's. This is a problem for me since I ditched 32-bit years ago for the memory availability. Any thoughts?

Any and all help is appreciated.

THanks,
Shannon

1) depending on what you want to do, you may be able to use a 2D CAD program.

2) Mach3 is a machine control program. It does come with a free, basic CAM program (LazyCAM) that works with 2D drawings only.

For 3D models, you need a 3D CAM program. There are at least 2 that work inside Rhino. RhinoCAM and MadCAM.

3) Assuming you're talking about about a machine control program?

Mach3 will run on a 64 bit system, but you can't use the parallel port. When using Mach3 on a 64 bit system, you need to use an external motion controller, such as the Smoothstepper. Warp9 Tech. Design - Home of the SmoothStepper - Home

Gerry,
Thanks for the reply. I checked out the link you posted and am more confused than ever... Can you explain the chain of equipment I need? Ex. computer --> smoothstepper --> motor control --> motor, etc. Does this smoothstepper serve as the breakout board?

To be clear on the software, I am going to use some CAM software (RhinoCAM or similar) to transfer 3D solid models to Mach3. Mach3 will then create the tool paths? So Mach3 is actually the software which controls the machine. How much user interaction is required in Mach3?

I realize these questions are basic, but I am just starting to get my feet wet and cant seem to find an FAQ on the software/hardware interface. If you know of one I would be happy to get my answers there. Thanks for the help!

Computer = Machine controller but if using a SS then the SS does the motion control

The SS does not serve as a break out board

Rhino draws the part, you then create a toolpath using the CAM, Mach3 produces part from Gcode generated from CAM

I suggest you use a breakout board as they make wiring easier and can have built in relays for controlling spindles etc and safety devices like charge pumps

So to be clear, my chain will be computer --(USB)> motion controller --> breakout board --> motor control --> motor?

I am clear on the software. I will use Rhino to build the 3d model, RhinoCAM to develop the tool paths, Mach3 to send the toolpath via USB to the machine.

I am so darn confused with all this I just wish I could find somebody that will hand this to me in a box and say, plug this here, plug that there. I guess that's half the battle of learning...

Thanks for the help.

You can have it like what you want,(Plug & Play) But it just costs a lot more

Any recommendations for suppliers? I see a bunch on eBay, but that always makes we queasy dropping $400+ trusting somebody in China will deliver. I do a lot of work in China (shipyards) visiting several times a year and know one thing for sure, you stand a 50/50 chance of getting ripped off on any transaction you make over there.

Do more research before spending your money, or you stand a better than 50% chance of buying things twice.

I agree I would not by any of the Ebay machines going by the different post on Zone, most have a lot of trouble with them, you do get a lot for the money, but is it worth the rebuild to make it work?

How big a machine do you want & what do you want to cut with it

[sgalway]

I have a Rong Fu 31 and plan to use it for cutting aluminum, plastics, wood, mild steel.

From what I understand I need some motors in the 350 - 450 oz-in range and supporting electronics. Its the electronics that are confusing me to death.
