Dmitry,

I just came across your thread here and noticed that in the pictures of post 6 (I think) you ground the shielding if the control cables from the BoB to the drivers on the cooling plate. This is incorrect. Officially they should be grounded on the BoB site, see this post http://www.mechmate.com/forums/showt...69&postcount=2

great build, I like to pictures, and I wish my rail grinding was that good!

Ries, there is nothing wrong with the way in which Dmitriy is grounding his Bob shields. Do you want to discuss it further in another thread?

Nice building so far.
Good luck!

@Gerald & Dmitry,

I think I did see that the shielding of the control (BoB to Drivers) is attached to the cooling plate of the drivers, I cannot enlarge the picture to confirm. it would be better to ground (put on the 0V side) the shielding on the Bob side.

if you want we can discuss this on a other thread, I am far from a authority though in this subject and haven't been doing electronics design for over 12 years.

Greetings, Ries.

I do not understand, what problems? Try to draw a wiring scheme of it.

Dmitriy,

shielding of signal cables should be done at the signal source, in this case on the BoB (PMDX) side, not on the gecko side.

Shielding the signal cable on the cooling plate of the gecko driver might even introduce more nasty effects (EMI) because usually this ground is what's called dirty.

Since the ground of the power supply is attached there, and the gecko's are connected to the power supply (high current) this might introduce more EMI then not shielding at all.
Also EMI in the ground plate might come from external interferences outside of the box it's not 0V! and might contain any other fluctuations from for example plasma welders, drills, saws etc.. So don't use a dirty ground for shielding signal cables.

Beside, from computer tot BoB is electrically connected, but from BoB to Gecko it's isolated using opto couplers (on the gecko side) . So it's best to keep this circuit as much separated as possible.

Lastly, and this is what gerald also mentioned, reducing EMI in your signal cables can also be archived by:

1) Not lying the signal cables and high power cables (110V, gecko power, stepper cables) close next to eachother in one line, it might look better, but it can introduce a lot of EMI in signal cables. Lay thm as far away from each other as possible, left, rights side of your control box for example and in separate cable ducts to insure separation.


2) If you do need to cross (in space) signal cables then do so in a 90 degree fashion, so
they cables don't 'see' each other. This technique is also frequently used in RF circuits where coils need to be layed out 90degrees from each-other to minimize interference.

Ries, many thanks for a competent substantiation. I think, already soon I can check up it in practice And unnecessary contact pieces to cut off is never late.

Dmitriy, your build is looking real good. Those belt drives are nice and looks like a very polished design.

Charles, I was just about to say the same thing but my shop looked a little like that until I cleaned it out. I'm sure a fresh coat of paint on the wall would make a huge difference.

Hi, Irfan.
One of my trades - the designer. Therefore I professionally own Corel Draw and Adobe Phonoshop. In most cases I use these programs - for me so more conveniently and easier. Also I use AutoCad and many other programs.
