Hey Kevin,
I did not mean what you intend to do with the machine, but what the machine suddenly surprisingly intends you to do, thereby preventing that you work with the machine, but stealing your time (and enriching your (possibly unwanted) experiences )
As an example, the stall homing method that the machine offers is considered by many users as not repeatable with sufficient precision so they are required to use a method with the Touch probe and a clamped block instead of it. It is however possible to retrofit inductive proximity sensors as limit switches, the Onefinity CNC supports it, but you would need some 3D-printed parts to attach them to the machine.
Or, if one day you find that your Z-axis moves up and down as it pleases and ruins your workpiece and your wasteboard (the Z plunge issue), you might find that it’s because the curly Z cable is, unlike real drag chain cables, no cable made for permanent motion in a CNC machine and one day starts with internal cable breaks exactly where a strain relief is missing, or you find the second cause, the susceptibility to EMI, because none of the stepper cables are shielded and the router as well the upgrade to a spindle and VFD are a heavy source for EMI, or you find the third possible cause, that connectors can make problems (see also here), which may be caused by the fact that you did not yet retrofit strain relief to your machine, which the machines unfortunately lack. In this case you may want to procure what is needed to make new cables yourself. The same applies if you want custom length cables which would be the case if you want to mount the controller further away, if you suddenly find out that the way you wanted to position machine and controller is impossible with the stock cables. Or better start with drag width chain computation while you’re at it in the first place. Okay, on the Elite, they finally have drag chains. But what if it suddenly does this? Also even if Elite has a spindle option now, the drag chain is only 30 mm wide, so no chance for a water-cooled spindle. They sell additional clamps for the coolant hoses because the drag chain is too small.
So what I meant is, you can find such things out before buying only by taking time to dive into the forum and reading the experiences others had and reported. Otherwise it may be that you must repeat every problem and every issue yourself (which I do not recommend).
