    It is a little heavier duty machine.

    Based on the linear bearings on the Pro machines.

    Default Probotix Nebula vs CNC Router Parts CRP4848

    ***I think I posted my original thread into the wrong sub category. Hope this one is more appropriate for my question.


    I'm ready to pull the trigger on one of these two machines, but cannot make up my mind. I hope some of you can assist me with this decision by sharing some of your experience and knowledge between these machines.

    Little background, I'm a hobby carpenter and will use to machine mostly to make one off parts or .... the more likely option ... make BS parts with no real use.

    I'm looking at the below (2) models with options:

    $4,699 - Probotix Nebula
    $120 - Z-Touch off Puck
    $4,819 = Total


    $2,595 - CNC Router Parts CRP4848
    $1,560 - Plug and Play Nema 23
    $229 - Track Kit
    $130 - Auto Z Corner
    $170 - 80mm Spindle Mount
    $4,685 = Total

    I'm not including the Spindle cost in either one.
    I understand the Probotix also includes a PC, which I think I can put together for about $400 if I were to go with the CNC RP one.

    I would greatly appreciate anyone's input. If there is a better option for under $6k, please let me know.

    The OP specifically asked about the CRP series. We have a CRP series machine that we use to cut the spoil boards and the dust troughs; and there is nothing they can do that our Galaxy series machines cannot. In fact we are constantly having to adjust the cold rolled bearing mechanisms, and the machine is not near as precise as our Galaxy series machines.

    I had to laugh at some things with the probotix. They claim using ACME screws is an advantage over ball screws, because it means they don't need to use a lathe... Buy a lathe guys.
    200ipm rapids is sloow.
    Round rails
    Weak gantry.

    Not worth it

    The OP specifically asked about the CRP series
    He also asked about alternatives for under $6000.
    The CNCRP Pro machines is far superior to your machine and the standard CNCRP machine.

    Might be a little bit higher than your budget, but the FLA Saturn 4x4 would worth a look.

    This is a MUCH better machine than the other 2 you're considering OP. It will be orders of magnitude more rigid and capable of running without adjustment for quite some time. They also currently have a 25% off sale on this machine with free shipping. I don't think you're going to find anything that competes with it, short of looking at the used industrial market and waiting for the right machine to come along. The CNCRP PRO line is also very nice, but the FLA Saturn is likely considerably more rigid, as it has a welded steel frame.

    With all due respect, sir... "superior" is not a technical term that can be quantified. If its not more rigid (its not) or more precise (its less, actually because of the rack-n-pinion), or more reliable (nothing is more reliable than LinuxCNC and American made controls), then its not superior in any way that means anything to the user. On top of that, the Galaxy series machines are precisely assembled before they are shipped, which could make the biggest difference if you are one of the many who don't have the time, skills, or maybe tools to assemble such a machine in a precise manner.

    The Galaxy series machines are not for everyone, perhaps not even you. But they are a very high quality product that fills a specific need in the market. Writing them off as inferior "because I said so" is not accurate, nor helpful to anyone.
