Production grade CNC router Vs Homebuilt CNC router advice

[davo453]

In a production machine obviously you are paying for the development time and hope that that time was well spent.

If you make your own the key is as said already in the electronics and later on software to drive it, when I built mine I experimented with the mechanics of the thing. First off I built a very cheap mechanical prototype and gradually improved it but good electronics is the key.

I got lucky in many ways, I built my electronics BOB and drivers from kits supplied by Luc Degrande a very cost effective (if not easy) way of doing it and they have proven to be very reliable (touch wood) over what must now be several thousand hours of often 2 hour long runs.

Like many things the more you read the forums the more confusing it can be and in the case of CNC people get quite snobbish about design.

For example mine still uses plywood as a main ingredient but the use of linear rails and bearings has negated that to some extent.

Good Luck
