Wellllll I Guess I Am Going To Cnc My Enco 45 But Slowly

I too had the same problem with the Z axis bleeding down on my one-shot lube system. Instead of using check valves used ball valves. I split the feed line into two circuits with a tee. One side of the tee feeds the X and Y axis and the other side feeds the Z axis. Each of the feed lines has a ball valve so I can close off one of the feed lines and pressurize the other. In essence the ball valves are manual check valves. I no longer have a problem with the Z axis bleeding down. Just another way to solve the problem.

Good input, thanks. What size ball valves did end up using? Bob

They are threaded 1/8" pipe female on each end. I'm headed out of town this morning. Will post a picture of my setup when I get back on Monday.

I cheated on the check valves, I saw a post over on cnczone so I have two smaller manifolds on order and I ordered these check valves to keep from having back flow troubles. the bijur will feed a 6mm Y split which will then feed the check valves and then the manifolds.

That is the way I am setting up mine with 2 manifolds. Thanks I will get them coming.

Well I have gotten most of what I need to start configuring the motors, drivers, mach 3, and break out board set up in my shop with the laptop all cleaned up and spiffy.
Steve the post you made on http://www.hobby-machinist.com/threads/rung-fu-clone-rf-45-zx45-cnc-conversion.8187/page-15 your set up, will mine be the same????
I will take pics of my operations center this evening and see if I have missed anything. Thanks again for all the help.

This is my assembly/ testing area, hope to get the system hooked up and tested soon.

Here's a picture of my setup. The valve on the left feeds the X and Y axis manifold and the right valve feeds the Z axis manifold which has the three feed lines for the two dovetails and the ball nut. Notice that the Z axis feed lines are filled with oil. I pumped up this circuit about a month ago and closed the valve. There is still oil in the lines up to the push-to-connect fittings.

Hope this clarifies my description in my previous post.

That's great...thanks for sharing. Bob

Yes thank you, that looks easy enough to use.

Toms, thanks for the valve photos, clears up a lot. Bob
