Howdy from Montana,
My name is Allan and I've been interested in cnc routers for quite sometime now and am finally getting serious about buying one.
I just recently came across the probotix line and am really interested in the Nebula series. I'll try to ask my questions in the appropriate sections.
A little about myself. I live and work on a large ranch in Montana and absolutely love it. I have a basic woodshop, plus own a portable bandsaw mill. I've slowly worked my way from firewood to buy a mill, sold lumber and then the mill to buy a bigger mill and any more I mostly only saw box elder and box elder burls. This is possibly the next step for me as my retirement plan. I'm still plenty young at 50, but a guy has to keep the options open. :D
Thanks for having me on your site,

I will attempt to answer your question.
The machine comes with LinuxCNC control software loaded on an included computer. This computer and software are dedicated to the operation of
the CNC router.
You will need an additional computer for your design and toolpath generation work and to create machine code from the toolpaths(postprocess).
You need software to create the design and then software to create toolpaths from the design and software to postprocess the toolpaths.
This can be a single softtware package or it can be one software program for design, a different software program to create the toolpaths and a third software package to create the machine code. Usually the software that creates the toolpaths will also postprocess the toolpaths to create the machine code to drive the CNC machine.
As you mentioned, V-carve Pro by is a single software package that will allow you to create 2D designs, 2D toolpaths and postprocess the toolpaths into a machine code to drive the CNC router.
If you want to do 3D carving, I would recommend Vectric's ASPIRE software package.
It includes all of the V-carve Pro capability plus the additional capability to create 3D models (designs), 3D toolpaths and postprocess the toolpaths into machine code. Aspire also includes over 100 models (3D models) ready for you to carve or use in creating a project which incorporates 3D images (models).
I used V-Carve Pro for a couple of years and then upgraded to Aspire and have been very satisfied with Aspire.

Hannah024, thanks for the info, but now I'm a bit lost. This machine comes with a computer pre-loaded with the control software, yet I need an additional computer for the Vectric cut2D software that does everything that I need in 2D, correct? Although I have an extra computer sitting unused already, I don't understand why I can't put everything on one, is the pc that comes with it not big enough for everything or is it a different issue? Can you please set me straight on this?
Please know that everything I say is meant very respectfully, I just talk rather bluntly.
Thank you for your time.

The computer that comes with the machine has Linux software on it the other program needs Windows to run.

Thanks Pete. I found a good video on their set-up and running a comet, I believe it was, and now understand. If that's the worst stumbling stone I trip on I'll be simply amazed. :lol:

Those are not stumbling stones!
They are learning opportunities.
Yes, there will be Many, Many Learning opportunities.

Plus, I've heard it said that you do NOT want to be doing things on your CNC computer while it is running. And often I have found that sometimes a tool-path has to be tweaked once in a while while others are being carried out by the CNC.

And you don't want you CNC computer hooked up to the internet. Been a few stories of machines trying to up date themselves and screwing up the CNC programming.

I have my Aspire set up on my laptop and I can "play" with it anywhere I happen to be. Then any file you have, any changes you make, you just throw it on a memory stick and load it on the CNC.

It will all start making sense when you get into it!! Biggest thing is, don't hesitate to ask! Lots of knowledge around here - not me - but others!!

Thanks KLWestfall, you make some good points and I now understand, it was just the ornery side of me saying "WHY". I hadn't even considered how the internet would affect things, but agree that I'd be worried.
I like your use of the word "play". I use it often describing jobs that I've had and folks try to call me on it. I generally tell them if they don't play at their job then possibly they're at the wrong job.

Hi Justin and welcome to the forum!

Thanks Keith and Mr. Hannah for your very helpful posts.

If you ever have a problem or question no matter how small please post here our customers and our team are great at sharing knowledge. If you cannot get an answer here you can always email or call us direct.

And Keith is correct - we do NOT recommend you hook up your computer to the internet. You are welcome to put it on a network if you are comfortable with file sharing on a hybrid network however if Ubuntu does any kind of update (which is easy to accidentally do)_ it will break the real time kernel that LinuxCNC runs on and you will have to reinstall the entire operating system/LinuxCNC compilation. Not a huge task but annoying. Also we have done extensive testing on this exact version on our machines and have found it to be the best, any new versions or GUI's you install limits the support we can provide and you can be pretty sure there is a reason (ie issue we found) as to why we are not using that version. The most common way to put your G-Code files on the machine is exporting from your CAM software on your windows box to a thumb drive and moving the thumb drive to the LinuxCNC box.

Thank you, Probotixmissy.
Initially the idea of using 2 PCs baffled me, plus me being hard headed didn't help.
Thanks for the help.
