So I just ordered a Chinese cnc router - a 6090 heavy variant - 60120 from acctek with vacuum table and rotary option. I requested that they video it running through some tests before shipment.
I'd like to ask the forum for some suggestions as to what those tests might be from you guys who have been around these machines for a while.
I assume it would be good to see how level the spindle is cutting with the table so I'm thinking of having them cut a max size rectangle. Also a large circle to see how it closes.
I'm not sure what to ask for showing ball screw calibration and other fine tuning.
Any suggestions would be greatly appreciated!
If these is any interest I would be happy to submit a machine review when I get it.
there is a great youtube channel, at-man. he bought a used fadal and made an eight video series of how to calibrate a machine. he goes in depth into all problems, a great tutorial. it is long to watch but the information is invaluable.
