Where can I get some quality switches?

THanks

Its as I suspected, just wanted to double check. Thank you!

Im planning to wire for bipolar parallel. I understand that all the wires will be paired up and then you will be left with 4 leads. The question is does do the wires have to be paired up at the...

Hi,

I had not been around to follow this thread. Is the drawing in the first post correct at this moment?

Well I got good news this time. First off, I managed to get the Grex connected again so I could load firware again. It turns out that the problem was in my Internet Protocol (TCP/IP) Properties. Try...

I baught a crossover cable from staples too. I managed to get the firware loaded for Grex100 now I cant get the firware loaded for mach.

Yeah, I get the same result, the CH-1 lights come on (very dim) and then 10 seconds later the it boots up and the run LED turns green.

My problem with the GREX is I cant get the firware loaded...

My screen resolution is 1920x1200. I really have no real clue what the problem was but I dont think the resolution was the problem as I tried every possible resolution. So you cant see any buttons...

I caved in and just reformatted the pc...It works now except im running into other issues not related to the Grex...:mad:

I got the same setup your getting and Im planning to use a spring as a preload. I looked at the preloads for some techno isel ballnuts and they were rated at around 100lb. As for the $35 flange, I...

Hi, I to am unsure about all the electronic stuff. Perhaps the best thing to do is to order some type of packaged deal.

Wow, they look great! I cant wait until I get my machine built.

Your machine and setup look great! Do you by any chance have some more pics of stuff you have cut out with it?

Im not sure if you were asking me. But this is my machine in the "works."

Thanks for the replies. I think I will try doing in on a lathe when the time comes. Im a student so I have access to universtiy machine shop.

What are the easiest ways to cut a hardened steel shaft? From my understanding, larger shafts are generally just case hardened right? You think it could possible be cut on a lathe with the right...

Thanks a lot for the information. It is good to know because I have almost finished designing a machine around them.

Just so understand more clearly, do you mean the play as in the axis of rotation in the pic below? I guess Im hoping it is because 10 degrees of play in any other direction could cause a significant...

I emailed VBX bearings and asked who makes the rails and this is the response I got.

" They were made specially for VXB, unfortunately, we don't carry any CAD files"

Thanks for the link. Do you know who actually makes the rails? If not do you suspect the orgin of these linear slides to be from Nordex?

Yep, the price very attractive for me especially because the rails are supported. I know it is possible to get some brand name linear slide rails off of ebay for an even lower price but then you...

Im actually planning to buy three and cut them to use on all three axis because Im not building a very large maching. Then I would buy some bearings serperately to complete the other axis.

Has anyone ever used or heard anything about the linear rod/rails from VXB bearings? I was looking at the one below to use for a new router.
