Advice on New Robocutters X4

[JAZZCNC]

Ok well on looking again it's actually much worse because I missed you said X4 when I was actually talking about the Rhino CNC version.
The X4 is Total rubbish and I've just been reminded that when asked same question some time back I replyed " It's only fit for Icing cakes" and nothings changed since then. . .Lol

Regards your questions about rigidity/accurecy then both are subjective to use. ie For Icing cakes you don't need much of either.!

But for most other work then it's a sliding scale and balance of both along with another unmnetioned but very important area.? Repeatabilty.

Wood's and plastics don't need the accurecy of watch making but they do need certain amount of ridgidty. Machine strength and ridgidity have big affect on the finish of work and the feeds you can cut that work at. It also affects other less thought about areas like tool wear and machine wear.
Repeatabilty is also important in some cases, wood working however doesn't need micron level repeatabilty, but it still needs to be factored in and moderately repeatable.

So for woods then in general accurecy of 0.01mm is more than enough. Ridgidity is hard to quantify but in general you need relatively strong machine to handle the higher cutting feeds wood requires. If the machine is weak then you'll get resonance which affects several key areas. Quality of finish is poor, tool life is shortened, machine component life is shorten and in some cases machine performance is affected badly.

CNC reliabilty mostly depends on the quality of the components used. Esp the electronic components. This is the Single most troubles some area of a CNC machine that is fitted with cheap poor quality electronics. Unfortunately for poor unsuspecting buyers it's also the area where profit greedy builders cut corners and fit rubbish.

In general if the machine is fitted with decent quality Components and built strong enough. Is fitted with quality electronics and correctly wired then you won't have any reliabilty issues.

Where to buy for between £1-3K for machine 1500 x 3000 from a company then it's not possible. Not for one that's any good anyway.
To do correctly then It would only just be about do-able if you built it your self. And I'm only talking about machine suitable for wood,plastics etc use.!

Edit: Also picking up on the software side. You fail to mention CAM. Cad skills is only one half the process and it's not a case of creating a 3D model and sending to machine.!
It's often made mistake to think that a 3D model is required when infact for many things you only need 2d Vector lines/arcs. Even when a 3D model is used the CAM software just uses the 2d edge geometery for anything but cutting true 3D surfaces.
So factor into the equation/learning curve CAM software.
