RE: cnc head
Yes it does its such a good copy it even has the same shortcomings as the real Esky cnc head. Its just made from lower quality alum is all (still have to retap all the threads to full depth and loctite everything together. Get yourself a 2mm tap and cut it back several threads to make a plug or bottoming tap out of it, and it will do the job. I went to the extent of even replaceing all the screws with longer ones, Start with a screw that is too long and cut it down with a Dremel so it fits all the way in, careful of the threads you do not mess them up cutting it down.
