Mill on ebay

[Hellfire]

The x and y axis aren't as bad, but with no ball screws it's going to need constant attention.
the guy won't help at all, I offered to pay for the ball screws etc and fit them myself if he machined them to suit the mill. No go.
he had it setup so the x axis referenced to the right. (Table move right ) never see that before on any mill.
what the hell is the point in fitting servos with encoders to a standard lead screw lol.
so the guy won't answer my emails or answer the phone, he has them on eBay as a classified listing. So no come back .

Mine dosent reference, he has the switches setup as home and limit. So when it hits the switch the machine goes into fault condition .
did you raise your concerns with him.

I sent a couple emails about accuracy as I was getting .1
And a couple over issues not being able to calibrate backlash etc.
The machines definitely need gas struts on the z had problems returning to z height on a job in the same place.if I can help with settings in anyway let me know .

Yup same machine

[Hellfire]

Was he any help to you?
the settings I can do, the machine cost me £4500 with the fourth axis and delivery. As it is it needs a refit, and I don't have time to do it. So I am at a loss.
he won't answer emails or answer the phone.

Wow I I only paid 3200 if I'm correct with the 4th axis.the 4th is only 150 new.he did reply to one email after I complained about accuracy and loosing steps he suggested getting the encoders setup but unfortunately didn't seem worth it at the time . £4500 does seem more as he sold an identical one for 3800 a couple months ago.

[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
