Opinions sought on cheap desktop PCB milling machine

[John S]

This was done on a KX1 mill as a test for someone who wanted to do roughly the same prototype boards with no lead time.

Not knowing sod all about PCB's, only JCB's, I asked for a file, this was code generated direct from one of the PCB software packages.
On the left is the code as sent but the tool depth was too deep so it was edited and the one on the right run again.
You may recognised the pad layouts but as scale the holes which were in the scrap sample board are 3mm.

A Krees spindle will cut these tracks with no problems, no bearing update needed, I do finer work than this with no problems.
