I had bought a 'cheap' cnc controller from Ebay and had nothing but trouble with it :s
after recieving the controller the chip burned up after 10min's of use..
-> recieved a second one and burned this one too!
-> recieved a 3rd one and this one lasted for one hour but guess what .... burned too!
after reading some reviews it seemed these controllers were just not designed right and therefore being sold on ebay for a 'good' price.
... so one tip for all you other builders: never buy a TB6560 on Ebay!!
now i've ordered a more expensice one (got my money back from the previous controller) and hope this one will work as it should.
i should get it tomorrow so i can begin testing it :)
