Mill on ebay

[Hellfire]

Yup was £4500 with 4th axis, delivery was £250

would the encoders not need to be calibrated only once though, sounds more like backlash to me and wear on the lead screw nut. Any way the machine isn't capabile of 0.01 accuracy as stated in his ad

It might be worth mentioning here the vendor's ebay username, his town might help in case he opens another account in order to lose his history with the current one, he might assist his previous customers if prospective ones start asking all sorts of awkward questions about his wares ;-)

If you paid via paypal and they aren't interested but the transaction was funded with a credit card you can still talk to your bank about fraudulent mis-selling and get them to reverse the credit card payment which will such the money back out of the vendor's paypal account, leaving it negative if he doesn't have a balance.

You should report him on the Mach3 support forum for selling bogus licenses, they take a fairly dim view of this and given the very reasonable licensing cost it does make him look rather unscrupulous.

On the subject of setup Mach3 you can use one switch as limit and home without errors when homing. Mach3 also has backlash and leadscrew mapping compensation settings which would probably at least get you going, adding an automated oiler would keep wear to a minimum.

If you want to take some of the vertical load off the Z screw it's worth considering a cheap and easily set up pulley and weight arrangement, leave a few pounds of load on the screw though.

Thanks for the help bud, I am going to give him one more chance to reply before I put details up. Not looking good though.
i paid by bank transfer, so nothing I can do there.

Ok still no reply from him.
before I post the link to the mill, can I ask a question.
am I being unresonable in expecting this mill to have ball screws. Can a mill be 0.01 accurate on all axis with ordinary lead screws. Is it suitable for production work.
ok three questions

No No and No Clive

From a long time i feel there is a need in this forum to have a WALL OF SHAME. Cause i am tired of reading overexcited stories from newbies. Lets hear the truth about the bad stuff they sell using fancy words out there. In my early learning stage, before a couple of years i also got scammed with my first machine. All were praising it on the Zone and i was like a stupid fish that bit the bait.

Hopefully there is a solution to your problems. I believe as ball screws are quite cheap, best would be to think it well and spend a bit more importing it from China and fixing it yourself. cause obviously the vendor will do nothing.
