Connecting to a CNC machine, pros and cons of USB vs PP vs Ethernet etc.

[JAZZCNC]

Hi,

Jazzcnc, at no point in the discussion did Jess make personal comments about or to you, in the way you have in reply to Jess, please respect other forum members, as rightly pointed out by GEOFFREY, you are a Forum Superstar , we know you for greater things ;-).

You know me Lee I say it the way I see it and he was being a provocative ***REMOVED*** towards me so I said it like it was.! Not often I call someone a Troll on any forum but he showed all the classic signs when he continually argued back against Experience over Theory with a person so experienced when he's only got 20+ posts to his name.!! . . . .(post of them arguing with me.!)
For god sake when things are developed whats the procedure.? First it's theory on paper then it's Tested which is experience. Often the Theory doesn't match the test results I know this all too well building Bespoke machines and several years working in Motor cycle racing R&D.
I help and share what i've learnt thru experience to genuinely help others on forum avoid taking a route I know can or will lead to hassle. It's not to massage my Ego showing off my theory knowledge. Anyone who's dealt with me knows this to be true.!!

The simple matter of fact in this case is that USB motion control devices available for MACH3 are not as stable or reliable compared to there Ethernet brothers for what ever reason.! End of the day it doesn't matter to the end user what the reason is all He and I care about is that the machine is stable and reliable.
Why USB has brain farts is not my concern wounce i've established it's not my work or the setup of the PC or machine. Long ago the USB smooth stepper taught me that chasing Ghosts is time consuming and expensive. In the case of USB smooth stepper it was a design fault BUT. .!! Every USB Motion control device, without exeception, I've used withb Mach3 has at some point dropped out while cutting. No matter the cable quality or length etc. This is not the case with Ethernet.!! . . . Yes occasionally you can have troubles getting it to talk to a device but wounce they are chattering away they keep on and never stop until told to do so.!!

There I'm done and said my piece.

Now Lateatnight if you haven't or can't get to the bottom of this then contact me via PM to stop certain ***REMOVED*** interfering and I'll give you my number. I'll also give a friend a call who I'm sure will know all the tricks the sieg can playup with.!
