Please give us an update on the project when you've tried it out OK......

Hi Ray,

Looks like a little China nerd had a pretty good sense when composing my set,  I cant find any reason to make complaints, the set is running damn fine, so this time I didn't go wrong ...... :-)  My set from Long is pretty low noise as well, nice when working near by ......

Regards
Leif

Yes,  I can Se your point about the deflecting drill,  but if yo have a setup that loses a step once in a while, defelection is no problem...... you will soon See new rows of nice little holes here and there.... :-)   the  test with the 2 squared holes  could be OK though , but I really don't experience anything indicating that I have any lost step at all.  edges looks like laser-cuts.

All the best

Well, maybe this test needs a little explanation to be understood.....  the holes where diagonal to the milling table and the mill drilled the same ten small 1 mm. holes 125 times, and all were still perfectly circular after the entire process , I guess that's a pretty good way to look for lost steps.

I tried a test with my Bridgeport....... drilling ten 1 mm holes diagonal on a piece of alumina
and the machine was set to repeat the hole process 125 times,  all holes were totally
perfect, so no lost steps here either, but the geckos are fine .... I tried a set last year on a
mill from Taiwan.

Hi Natefoerg,

I guess the higher voltage and a bit better drives make your setup performing close to the Long set
that I bought on Ebay .....

All the best

Hi,

After a little tweaking, the set has been a nice surprise to me, the speed and precision is more than I ever expected, so I`ll recommend the set to anyone who need a good performance without paying a kingdom......  Make sure you have ball screws on the machine OK, those acme screws need a bit of software compensation almost every time you use your mill.  The Long set I bought is OK for a Bridgeport, that's my opinion on the issue.

All the best

Well  BR549.....lots of good sense in those words, Ill stay with the steppers for now and see how they work and forget about the speed for now.  I know the Hp decides how deep and fast one can cut. but every little movement takes time as you know.. :-)

Thanks for sharing your first-hand experiences Hood  :-)
